Text mode HSTX DVI output on the Fruit Jam 🔡🖥️🍓

Jepler has been working round the clock to get HSTX DVI (https://github.com/adafruit/Adafruit_dvhstx/blob/main/examples/02texttest/02texttest.ino) output support for the Fruit Jam (https://www.adafruit.com/product/6200) working - this mode is neat because its 'text only' - you get 3-bit color text, it does that by creating a 'resolution' of 91 x 30 characters, you can only set the color and glyph. However, the monitor output is a non-buffered 1280x720, with each scanline generated 'on the fly', so you don't need any SRAM. This could be great for something like a Z-machine emulator (https://en.wikipedia.org/wiki/Z-machine) or other text-mode-only computation.

HSTX DVI output on Fruit Jam! 🎨🖥️🎶🚀🔌

Woo! This xscreensaver-like demo shows random lines and colors displaying on a mini 7-inch HDMI monitor (https://www.adafruit.com/product/1667): it's a 320x240 'pixel doubled' display that is running from the Fruit Jam, an RP2350-based mini computer board (https://www.adafruit.com/product/6200). But what's cool is that we're now using the HSTX interface rather than PIO+core bit-banging. That means we now have plenty of extra resources for running the USB host... which is still being worked on.

TLV320DAC3100 first bops 🔊🎶💃🕺

OK, after many hours spent with Claude on writing a driver for the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/TLV320DAC3100IRHBR/2260591), we finally have it configured using our driver, and playing an MP3 stream on this ESP32. This I2S DAC has a particularly complex PLL and audio-routing system, so it's not one where you can just pipe in I2S data and have it magically play. One nice thing we got working on is the MCLK, which is generated from the BCLK, so it'll work great with anything from an Arduino-compatible to a single-board computer like Raspberry Pi. We're hoping to get the headphone detection working next so that we can turn off the amp when the headphone is plugged in. Also, it should be able to control the volume from the headset buttons. Also, we want to get the internal beep generator going so we can make tones separate from the audio stream for UI notifications.

Steamboat Stand: 3D Print Add-Ons for IKEA Coat Stand

You can 3D print your own custom add-ons for this coat stand from IKEA. 3D Files: https://learn.adafruit.com/ikea-coat-stand These playful 3D printed add-ons are inspired by an early 20th-century public domain cartoon. We think it's a fun blend of practical and whimsical product design that you can make yourself. The “Alganas” hat and coat stand from IKEA features a simple design that stands up-right and doesn't have to be affixed to the wall. The powder-coated metal hooks are perfect for press fitting 3D printed parts which actually offer additional space for extra items. We designed four add-ons that are inspired by elements from that iconic 20th-century public domain cartoon Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

A Compact Pi Compute Module Backpack 🍓🥧📸🎒

We used to stock a PiCam Module (https://www.adafruit.com/product/5247) that would plug into a Pi CM4 or CM5 - recently we went to restock it, but the vendor hasn't replied to our emails for many months. So, it could be a good time for us to design something that works similarly but with more capabilities. So we tasked Timon (https://github.com/timonsku) with designing something for us - we just said, "Make the best thing ya can," and he delivered! Check this board out that plugs onto the compute module and provides many great accessories: USB connection for bootloading/USB gadget, USB 3.0 host type A for CM5, micro HDMI, micro SD card for data storage on 'Lite modules, camera connection, and mount, two DSI connectors, fan connect, Stemma QT / Qwiic connection, and RTC battery. There's one shutdown button for CM5 and two GPIO buttons plus one LED. Timon's gonna try to add an EYESPI connector for our next rendering so we can get some I2C/SPI/PWM outputs easily. What do you think? We wanted to keep it compact and not too pricey (aiming for under $30 cost. We'll see if we can get it there) but were able to craft fairly complex projects in a small space.

PCM5102 and PCM5100 I2S DAC breakouts 🔊🎶

We're starting to stock a lot of chips that can do digital I2S out, which makes for great-quality audio playback. That's great when you have enough processing power to decode WAVs or MP3s in real-time. However, we could really use some better DACs in the shop. We like the UDA1334A (https://www.adafruit.com/product/3678), but that's technically discontinued - it's great because it doesn't require an MCLK that some boards like the Raspberry Pi don't have and doesn't need I2C configuration either. The PCM510x is a good family, too; it ranges from the inexpensive PCM5100 (https://www.digikey.com/short/z50cnp0h) to the PCM5102 (https://www.digikey.com/short/80z2nh3h) which has high quality output at a higher cost. This breakout could use any of the family chips & gives you all the GPIO needed with a 3.5mm headphone jack for line-level output. We're testing it out with some cool tunes from the adafruit soundcloud, check it out! (https://soundcloud.com/adafruit).

EYE on NPI - ST ST25R200 NFC/HF RFID Reader IC

This week's EYE ON NPI is neither-here-nor-there - it's STMicroelectronics' ST25R200 NFC/HF RFID Reader IC (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/st25r200-nfc-hf-rfid-reader-ic) a simple but powerful NFC/RFID reader and writer chip that will let you add a contactless interface to your next design. Thanks to the high power RF stage and dual antenna support, you can avoid the frustration of "where do I tap??" by giving you plenty of surface area for successful transactions. We're big fans of intuitive RFID/NFC interfaces using tags, they come in all sorts of sizes and shapes (https://www.adafruit.com/product/365) from standard business cards to microtags that can fit in a manicure (https://www.adafruit.com/product/2800). They don't require a battery, and can store up to a few KB of data, including encrypted/secured data sections so as to make the tag 'trustworthy'. They're often used for small-money transactions like copy shops, laundromats and public transport, where speed is important and we can store value on the card. Or for identification like access cards. With proper design, they'll work up to 4 inches away from a reader, don't suffer from corrosion or contact wear or affected by water/humidity. Reading and writing RFID/NFC tags, which use 13.56MHz as a carrier frequency, requires a proper chip that can handle the requirements of blasting enough RF signal to 'power' the tag, then transmit a command and receive the response before the quiescent power runs out. If you have a big antenna, this isn't too hard - but the real challenge is to manage it with a small antenna. That's the nice thing about the ST25R200 (https://www.digikey.com/short/5ttf9ptj) - it has powerful output drivers so even mini wearable-sized antennas work well. You can configure the outputs to be one differential or two single-ended antenna coils. If you want to design your PCB antenna, we recommend ST's website for NFC inductance calculations (https://eds.st.com/antenna/#/) it will let you determine the inductance based on width, height, copper thickness and trace width so you get maximum power transfer. The ST25R200's connection to the controller is over standard 4-pin SPI, so you can use any microcontroller or microcomputer with 4 pins available. An IRQ line is also handy to 'wake on card detect'. Other than that, the interface is fairly low level: registers are used to configure the RF section and encoding but otherwise, data is transmitted or received via two FIFO buffers. This makes the chip easy to adapt to the various sub-protocols and standards (https://nfc-forum.org/build/specifications) designed by competing RFID companies: ISFO14443A/NFC-A, ISO14443B/NFC-B, ISO15693/NFC-V, NFC Forum T1T, T2T, T4T, and T5T tag types, and proprietary protocols, such as Kovio, CTS, and B’. In order to make your life easier when it comes to implementation, ST has released RFAL an RF/NFC abstraction layer (https://www.st.com/en/embedded-software/stsw-st25rfal004.html) that is written in pure C so that it can be ported to any platform or compiler. To get started quickly we recommend the STEVAL-25R200SA evaluation board (https://www.digikey.com/en/products/detail/stmicroelectronics/STEVAL-25R200SA/25701817) which comes with a USB debug STLink interface, SMTable module, 4 pluggable antenna options including one flex PCB printed antenna, and two micro-tags for testing. If you want to integrate RFID/NFC 'touchless' support to your next design, the ST ST25R200 NFC/HF RFID Reader IC (https://www.digikey.com/short/5ttf9ptj) is small, inexpensive, and fast to get started with minimal external components, and ready-to-go drivers. And best of all the chips are in stock right now at DigiKey for immediate shipment. Order the ST25R200 (https://www.digikey.com/short/5ttf9ptj) and an eval board today and you can tap your way to contactless communication by tomorrow afternoon!

EYE ON NPI - Analog Devices MAX96714 Deserializer

This week on EYE ON NPI we're eatin' our Wheaties (https://www.youtube.com/watch?v=QvyInWTLM8s) - it's the Analog Devices MAX96714 Single GMSL2/GMSL1 to CSI-2 Deserializer (https://www.digikey.com/en/products/base-product/analog-devices-inc-maxim-integrated/175/MAX96714/737256) a way to send high resolution digital video over a co-ax wire without losing quality. These advanced serial-deserial sets - we'll call them SerDes for short - let you minimize cabling, for reduced weight and complexity when passing high speed video from cameras or to displays over single flexible RG coax. It's easier than ever these days to add high quality video or camera sensing to your products: boards like the Raspberry Pi can do dual 4K HDMI and up to two DSI / CSI ports on the Compute Modules (https://www.digikey.com/en/products/filter/single-board-computers-sbcs/933?s=N4IgTCBcDaIMYHsC2AHArgFwKYAIkIBM0AbLEAXQF8g) but the cables that they come with tend to be short, maxing out at 500mm long. (https://www.digikey.com/en/products/detail/raspberry-pi/SC1130/21658263) That's because the MIPI protocol used for data transfer is designed for ultra high speeds over low cost flex PCBs, from say a laptop motherboard to the laptop monitor or webcam. Now, we do sell looooong cables (https://www.adafruit.com/product/2144) that are 2 meters long but with the caveat that they are well outside the expected spec. They do work! But we wouldn't put it in a product that goes to customers. So what do you do if you have a car, where the seats and dashboard have monitors but the main processor is probably in the back of the car, far from the hot engine? That's where Analog Devices got inspired from the Cable TV of our youth (https://en.wikipedia.org/wiki/Cable_television) that would let kids of the 90's watch dozens of channels using...only one cable! The cable, in this case, is a coaxial cable: one copper wire surrounded by a plastic dielectric, then a braided metal ground return. Coax cables are flexible but rugged, and DigiKey stocks thousands of different types (https://www.digikey.com/en/products/filter/coaxial-cables-rf/475) by the foot or reel. So they make an excellent physical transport layer for video in aggressive environments because they are shielded yet flexible. With GMSL you need two chips: a serializer like the MAX96717 (https://www.digikey.com/short/3pcv09pn) and a de-serializer like the MAX96714 (https://www.digikey.com/short/3jqw8tj8). Between the two, connect said coax, then configure both sides for the data format you want and boom, you have a transparent video link! The serializer will take the digital data, then turn it into a serialized-packetized-data-packet on a single wire. That thin wire can fit into spaces that would normally be a challenge such as cars / aerospace where weight is at a premium, robotics where the shielding will protect the signal integrity, and medical where high rez cameras have to fit in tiny spaces. GMSL even supports 'power over coax' where a DC signal can be used as a carrier for the high frequency data - so you really can have one thin cable for everything. Depending on which generation of GMSL you choose, you will get either 3 Gbps or 6. A small portion of that is 'upstream' communication, thats used for IRQs, video/camera control and extra I2C or GPIO. If you need stereo or quad camera/video , you can use a quad deserializer: you will still get 4 coax cables in but it'll be smaller and perhaps better synchronized than having four separate deserializers. To get started, we recommend picking up the MAX96714-BAK-EVK eval board (https://www.digikey.com/short/nh82vrbc), which is not inexpensive but does have everything you need to get started with the MAX96714 (https://www.digikey.com/short/3jqw8tj8). Note you'll also need the serializer! One thing that's nice is that if you want to get set up with a Raspberry Pi to start, you can order the Pi Cam Eval board (https://wiki.analog.com/resources/eval/user-guides/ad-gmslcamrpi-adp) which is an adapter for the eval to use off-the-shelf Pi camera modules, pick up at DigiKey (https://www.digikey.com/en/products/detail/analog-devices-inc/AD-GMSLCAMRPI-ADP/21678785). Then to set up the configuration you can use the Linux driver to have automatic setup (https://github.com/torvalds/linux/blob/master/drivers/media/i2c/max96714.c) without a separate configuration program. If you'd like to try out GSML for your next long-distance video product, you can pick up the Analog Devices MAX96714 Single GMSL2/GMSL1 to CSI-2 Deserializer (https://www.digikey.com/en/products/base-product/analog-devices-inc-maxim-integrated/175/MAX96714/737256) today from DigiKey because it's in stock for immediate shipment! Book now and you can be zipping along MIPI CSI data at 6Gbps by tomorrow afternoon.

The Great Search: I2S DAC with Stereo Headphone + Speaker Out

We'd like high-quality I2S digital audio generation for our Fruit Jam board, and both 16-ohm headphone/line level out and a mono 8-ohm speaker driver. Ideally, we wouldn't need two or three chips to achieve this: the DAC would have headphone drivers and a class D speaker driver. We'll need I2C control, 3.3V logic, and up to 5V for speaker power. When you need a very specific setup for audio converters, sometimes it's easiest to go to the semiconductor website and search for the exact setup. (https://www.ti.com/audio-ic/converters/dac/overview.html) .Then you can book your order from DigiKey.

EYE on NPI - TMC5272 Dual-Axis Stepper Motor Controller and Driver IC

This week's EYE ON NPI is a Texas-two-steppin' motion controller that takes your 2-axis motion control to the next level: it's ADI/Maxim/Trinamic's TMC5272 Dual-Axis Stepper Motor Controller and Driver IC. We've been checking out many of Trinamic's great stepper motor driver chips lately and this one is the latest generation, with 2 drivers, plus motion control, for advanced usage even on boards that don't need real-time GPIO toggling for steps. Trinamic is definitely not a group that 'rests on their laurels': every year they are coming out with even more improvements to their awesome stepper motor drivers. This chip has 250 pages of datasheet and each page details yet another improvement or setting that will make your mechatronics fast, silent, and efficient. What sets the TMC5272 (https://www.digikey.com/short/0mq250r7) apart? Well, the first big thing is you get double the fun with two full stepper drivers for X and Y axis support. The voltage range is 2-20V, so good for low to medium voltage motors. The tradeoff is you can only get 1.5A max peak current, 1.1A sine wave, but for most users that don't have massive steppers that is perfectly fine. There's also a lot more 'smarts' in this stepper than the ones even from a couple years ago: 8-point motion control, no-loss/no-sense-resistor current management, 2D trajectory management over two axes, encoder or reference switch inputs, sensorless standstill motion detection. Of course all the fixin's you expect from the previous generations are there: silent stepping, UART and SPI and step/dir interface, stallguard, 1 to 256 microstepping, and diagnostic output But, it's in a 3x3mm WLCSP package: this means you'll need at least a 4 layer board and plugged vias. It also means heat dissipation might be more challenging than the drivers with the big ground pads. However, a nice tradeoff is that there is internal 'lossless' current sensing, so no chunky resistors are required. The upside of a WLCSP is that we have lots more pins for tons of interfaces. Each driver can run one bipolar stepper motor, and has multiple interfaces for control. As usual there's the STEP/DIR interface. This is great for usage with older designs that expect to toggle GPIO on each step. However, the S/D pins are shared with some of the cool sensors/encoders/switches. Plus all the really cool things the chip can do are too complex to adjust with just a few GPIO, so to really get the most use you'll need to use one of the packetized interfaces: UART or SPI. UART is great if you happen to only have USB for your computer: you can always just use a USB-serial converter, and the controller can be daisy-chained for multiple drivers per UART. If you have extra GPIO and/or a dedicated SPI port, we would recommend that since it's much faster and you can easily add more chips with one chip-select per. Some of the cool things you can do via the interface include a 8-point ramp controller: instead of stepping each motor and dynamically adjusting the micro-steps for speed/precision, the TMC5272 can do it all on its own. It can also handle knowing 'where' it is on an axis bar, by using the built in homing support. Homing can be done either by using the sensorless 'StallGuard' (https://www.analog.com/en/lp/001/building-better-stepper-motor-system.html) or with reference switches. You can wire the switches directly to the TMC5272 - good if you want to have slow motion homing since you don't have to whack into the end of the axis - and then let the chip manage where it is. Then you can tell it you want to move and when you want to get there, and the TMC will take care of the rest. For ultra-accurate motion control, you can connect an external optical or magnetic encoder to the motor shaft that will tell you exactly when a step has occurred. There's also a neat back-EMF sensor that can tell when the motor has moved while 'disabled' - good to know when you will need to do another homing step after re-enabling the motor. There's also an TMC5272-EVAL-KIT eval board that you can plug-n-play for instant stepper motor usage (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/TMC5272-EVAL-KIT/22107596), it works instantly with the TMCL IDE for trying out the various programmable settings (https://www.analog.com/en/resources/evaluation-hardware-and-software/motor-motion-control-software/tmcl-ide.html) and turn the motor via the TMCL IDE which sends UART/SPI commands over their USB driver board, so it's perfect for verifying the performance with your desired motors. If you want double the pleasure, double the fun of double-motor driving, you can pick up the ADI/Maxim/Trinamic's TMC5272 Dual-Axis Stepper Motor Controller and Driver IC (https://www.digikey.com/short/0mq250r7) from DigiKey today - it's in stock & ready to ship immediately!

Toddler Timer

Build a countdown clock to help teach toddlers how to visualize time. Guide: https://learn.adafruit.com/toddler-timer This project uses NeoPixel LEDs to represent blocks of time that can be setup to countdown any number of minutes. It features an OLED display to show the time remaining and a rotary encoder to set up the intervals and to start and stop the countdown. You can customize the blocks of time in the code and easily cycle between them with the rotary encoder. We think it's a unique way to show the passage of time with NeoPixel LEDs. This uses the Adafruit QT PY RP2040 dev board to drive the NeoPixels and the rotary encoder. CircuitPython makes it easy to change up the code so you can make adjustments or adapt to your roll your own countdown timer. You can customize the code to have different blocks of time or change the colors of the NeoPixel LEDs.

Fancy M4 Eyes on new hardware - a round display! 👀🧿👁️

Folks may be familiar with our HalloWing M4 (https://www.adafruit.com/product/4300) fancy eyeballs demo code - it's very dependent on the wired-up hardware. But of course, with our new round displays (https://www.adafruit.com/product/6178), we wanted to try wiring one up to see how it looks. That ended up being 2 days of hacking, but at least it's done now - we've refactored the code to support any SAMD51 board and any SPITFT display. It's not ready for publication yet; We juuuuuust got this working like 3 minutes ago... We want to abstract out the SAMD51-dependant parts so it could be run on chips like the ESP32 or RP2350 (https://www.adafruit.com/product/6055)!

Fruit Jam RP2350B credit-card mini computer with all the fixin's 🍓🍇💾

Coming soon! We were catching up on a recent Hackaday hackchat with Eben Upton (https://hackaday.io/event/202122-raspberry-pi-hack-chat-with-eben-upton) and learned some fun facts: such as the DVI hack for the RP2040 was inspired by a device called the IchigoJam (https://www.hackster.io/news/ichigojam-combines-strawberry-and-raspberry-to-deliver-a-raspberry-pi-pico-powered-educational-micro-66aa5d2f6eec). We remember reading about this back when it was an LPC1114, now it uses an RP2040. Well, we're wrapping up the Metro RP2350 (https://www.adafruit.com/product/6003), and lately, we've been joking around that with DVI output and USB Host support via bit-banged PIO, you could sorta build a little stand-alone computer. Well, one pear-green-tea-fueled-afternoon later we tried our hand at designing a 'credit card sized' computer - that's 3.375" x 2.125", about the same size as a business card (https://hackaday.com/2024/05/07/the-2024-business-card-challenge-starts-now/) and turns out there's even a standard named for it: ISO/IEC 7810 ID-1 (https://www.iso.org/standard/70483.html). Anyhow, with the extra pins of the QFN-80 RP2350B, we're able to jam a ridonkulous amount of hardware into this shape: RP2350B dual 150MHz Cortex M33 w/ PicoProbe debug port, 16 MB Flash + 8 MB PSRAM, USB type C for bootloading/USB client, Micro SD card with SPI or SDIO, DVI output on the HSTX port, I2S stereo headphone + mono speaker via the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/tlv320dac3100irhbt/2353656), 2-port USB type A hub for both keyboard and mouse or game controllers, chunky on-off switch, Stemma QT I2C + Stemma classic JST 3-pin, EYESPI for TFT displays, 5x NeoPixels, 3x tactile switches, and a 16-pin socket header with 10 A/D GPIO + 5V/3V/GND power pins. The PSRAM will help when we want to do things like run emulations that we need to store in fast RAM access, and it will also let us use the main SRAM as the DVI video buffer. When we get the PCBs back and assembled, what should we try running on this hardware? We're pretty sure it can run DOOM. Should that be first? :) We also need a name. Right now, we're just calling it Fruit Jam since it's inspired by the IchigoJam project.

The Great Search: 12V Lead Acid Battery for Bumper Kart

While debugging a non-working bumper car toy for BabyAda, we determined that the vendor, for some reason, provided a 24V DC power adapter when the battery is 12V and should be charged only up to 15V max! Uh-oh, it's time to fix it up. Let's head over to DigiKey to get a new 12V lead-acid battery that is the same size and shape so we can swap it in and recycle the old one. See the chosen part on DigiKey https://www.digikey.com/short/hhbnn97m ----------------------------------------- Visit the Adafruit shop online - http://www.adafruit.com LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/
