This week's EYE ON NPI is in a class of its own, it's Richtek's RT9120S Series Class-D Audio Amplifier with DRC Control,(https://www.digikey.com/en/product-highlight/r/richtek/rt9120s-class-d-audio-amplifier) a powerful amplifier with a wide operating voltage range, high efficiency, high wattage and many supported input formats We love I2S audio amplifiers here, they're a huge step up from PWM + analog amplifiers (https://en.wikipedia.org/wiki/Pulse-width_modulation) in that you will get much higher audio quality due to having true analog output and the DAC being tuned for 16, 24 or 32-bit audio. Most simple PWM is maybe 8 or 10 bits! As long as your microcontroller or microcomputer has I2S output support, you can use 3 or 4 pins to generate a bitstream of audio. For example, our Stereo Bonnet (https://www.digikey.com/en/products/detail/adafruit-industries-llc/3346/6573323) adds two single-channel I2S amplifiers to the Raspberry Pi so that it can drive 3 Watt speakers. But what if you need more MOAR power? This is where this I2S amp will shine: it can handle up to 30W per channel, stereo, and best of all it does not require an MCLK input signal (https://en.wikipedia.org/wiki/I%C2%B2S) so it will work great on Raspberry Pi computers of any size - although of course it will work on other microcontrollers and microcomputers as well. Let's take a look and some of the features we like in this chip. First thing to note is that there are a few options in the RT9120 family (https://www.richtek.com/~/media/AN%20PDF/SG017_2022.pdf): the RT9120 is the original, the RT9120S is an upgrade - it can now support 30W instead of 20W thanks to an RDS(on) as low as 90 mΩ and has 94% efficiency over 92%. It does seem to be pin compatible, so if you're using the non-S version this ought to be pin-compatible for an upgrade. This amp is Class D, which means if you're used to class AB amps that require massive heat-sinking, you'll be please to know you can likely get away without requiring a heat-sink - although you'll probably want a big back ground plane and 2 oz copper to help dissipate via the thermal-package ground pad. The trade off is you will need some passive components on the output of the amplifier, because it generates a high frequency - up to 1.5MHz - PWM signal that needs to be filtered down to 10-20KHz. It looks like this amp can use simple ferrite bead + capacitor outputs, but for the best EMI filtering and sound, a 10uH + 0.47uF capacitor is needed for each 'leg' of output. As this is a powerful amp, and since people will want to play it loud, and you'll want to avoid nasty clipping, the RT9120 also features Dynamic Range Compression (https://en.wikipedia.org/wiki/Dynamic_range_compression) which will slowly turn down the gain as the signal gets louder, so that you don't get square wave distortion. Lastly, you will need to control the chip over I2C, it isn't free-running. However, this means you can enable filters, change the Class D frequency, adjust the gain digitally instead of reducing the signal depth, and get an error output report to know if there's a short or open on the speakers, or missing I2S signal lines. However, if you're using a Linux-based system there's already a Richtek-authored kernel driver you can use.(https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/sound/soc/codecs/rt9120.c) Sounds good? I think so! And the fact that the Richtek RT9120S Series Class-D Audio Amplifier with DRC Control is in stock right now at DigiKey for immediate shipment at a very nice price (https://www.digikey.com/short/wqddcrqj) is music to my ears. You can also pick up an eval board for a very reasonable price (https://www.digikey.com/en/products/detail/richtek-usa-inc/EVB-RT9120SGQV/19914630) which will get you started quickly, particularly if you need to implement an I2C driver. Order today and DigiKey will ship your order instantly, you will be able to start adding booming quality sound to your design by tomorrow afternoon.

When you see a round display, do you think... pizza? planet? beachball? no? how about a Stargate animation! there's three parts to getting these funky displays working with raspberry pi over the DSI port: the SPI configuration of the screen, the I2C configuration of the ICN6211 converter and the DTO device tree overlay on the pi itself. all must be perfect for an image to appear! to make it less complex, we're going to only do one part at a time and celebrate the successes. we got the SPI config working with blinking the display on and off, and the ICN config was proven when we displayed a colorbar test pattern. finally we load a DTO up which will tell the pi to look for a 720x720 display off the dsi0 port (https://github.com/timonsku/display-overlays/blob/main/panels/HD40015C40/HD40015C40.dts) and voila! a 60Hz display with full color... we can even play any video off the desktop with VLC and it looks great.

we love a colorbar, oh oh oh oh! red, orange, yellow, green, blue... we love a rainbow when it appears on our TFT display! there's three parts to getting these funky displays working with raspberry pi over the DSI port: the SPI configuration of the screen, the I2C configuration of the ICN6211 converter and the DTO device tree overlay on the pi itself. all must be perfect for an image to appear! to make it less complex, we're going to only do one part at a time and celebrate the successes. we already got the SPI config working - blinking all the pixels on and off - now we look at the ICN configuration (https://github.com/timonsku/Adafruit_CircuitPython_ICN6211) - to make sure the PLL and resolution and sync's are correct (https://github.com/timonsku/display-overlays/blob/main/panels/HD40015C40/HD40015C40.py)! in order to separate it from the raspi MIPI DSI interface config, we turn on BIST test mode and have it display a colorbar (https://github.com/timonsku/display-overlays/blob/main/panels/HD40015C40/HD40015C40.py#L28). if the colors are in the right order we know that we have 2 out of 3 working, and we can move onto the next stage...Device Tree Overlay config!

yesterday we had the square 4" 720x720 TFT display (https://www.adafruit.com/product/5794) working with our Raspberry Pi DTO + ICN6211 configuration. now we want to move onto a round screen. one thing that was kinda nice about that screen is it does not require an SPI init code - it pops up immediately into RGB TTL mode. all our other screens require configuration. which means now we have a lot of variables: the DTO and kernel driver that writes DSI data, the ICN6211 configuration that sets the TTL resolution and sync, and the SPI config. that's a lot of variables! we're going to back up and just make sure the SPI init is good - to do that we use the ST7701 datasheet to find the 'all pixels on' command. by sending this at the end of the init string and seeing all white display we know that at least that part of the configuration is working, then we can work back and get the ICN6211 test colorbars and finally work all the way back to the DTO setting. display work is really hard but this is something we've done many many times so we are used to juggling so many configs. what really helps a ton is having a known good setup using the ESP32-S3 Qualia (https://www.adafruit.com/product/5800), so we are really glad we got that working first 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/ -----------------------------------------

This week's EYE ON NPI is so hot, yet so cool: it's the BeagleV-Fire from BeagleBoard.org (https://www.digikey.com/en/product-highlight/b/beagleboard/beaglev-fire) featuring the Microchip PolarFire MPFS025T-FCVG484E (https://www.digikey.com/short/ddw7fmww), a powerful Processor+FPGA combo SoC that has 4x 64-bit RV64GC Application cores, as well as a 23K logic element FPGA. The BeagleV-Fire outfits this chip with a tidy number of wired up peripherals so that you can quickly get started with complex computational requirements without having to spin up a custom PCB. Historically, the BeagleBoard folks have used ARM-core chips: their famous BeagleBone Black (https://www.beagleboard.org/boards/beaglebone-black) contained a TI-built ARM Cortex A8. But recently they've been experimenting more with RISC-V. RISC-V is an 'Open ISA' - which means that you get a well defined, high speed core, that adheres the the RISC-V ISA Specifications (https://riscv.org/technical/specifications/) and use implementations thereof, without having to pay ARM a licensing fee. And recently ARM has looked to raise those fees (https://www.xda-developers.com/arm-increasing-royalty-fees/) - which has a lot more chip makers looking seriously at RISC-V as an alternative core. Now, to be honest, RISC-V is not as mature as ARM, and you're not going to have as much language and peripheral support for it. But...it's hard to argue with free! (https://en.wikipedia.org/wiki/Disruptive_innovation) We've seen RISC-V show up in two spots: mostly in smaller, low-power microcontroller cores like the ESP-C6 (https://www.espressif.com/en/products/socs/esp32-c6), but more recently, in larger boards like this one. One nice thing about having the RISC-V cores be powerful enough to run protected software like Linux is that you don't have to worry as much about compiler or learning the peripheral management because you can just run Python or use the Kernel Ioctl interfaces for hardware - the hard work has been done for you! And for this board you get a ready-to-boot Ubuntu installation. Which is awesome because sometimes you get really odd distro's for SBCs that end up eating all your time and energy to get them into a modern state. Now that you have Linux running, you can use the FPGA to make custom hardware interfaces. To do that you'll need to use Libero (https://www.microchip.com/en-us/products/fpgas-and-plds/fpga-and-soc-design-tools/fpga/libero-software-later-versions) as an FPGA IDE, and use the MAC address of the BeagleV for the floating license. But it does look like you can run libero natively on the BeagleV - there's apparently 'gateware' examples that will be published, for the M.2, SYZYGY, MIPI-CSI and Cape/GPIO hardware interface. So those design blocks can be built upon or tweaked to fit your end-needs. Like other BeagleBoards, the files for the hardware are all published so you can look at the exact schematics and layout files (https://git.beagleboard.org/beaglev-fire/beaglev-fire), there's a Linux kernel fork (https://git.beagleboard.org/beagleboard/linux), Forums (https://forum.beagleboard.org/tags/c/beaglev/15/fire), and Discord chat! (https://bbb.io/discord) If you're burning with excitement to get your hands on one of the new BeagleV-Fire SBC's from BeagleBoard.org (https://www.digikey.com/short/fz434q52), you're in luck because they are in stock right now at DigiKey for immediate shipment! Order today and they'll ship immediately so that you can get started designing your very own RISC-V-based super computation device by tomorrow afternoon.

we took october off from working on this project, but we're back baby! a PR was submitted to allow DTO-level configuration of display timings , rather than having a specialized driver for each display config (https://github.com/raspberrypi/linux/pull/5640) which, if merged in by the raspi folks, will mean we don't need to do specialized kernel compilation or module work. at the same time im working on setting up the onboard attiny chip which will be used to configure the ICN6211 over I2C, the TFT over SPI, and manage the backlight. in order to make it possible to 'hot swap' displays without bustin' out a UPDI adapter, we'll store the configuration code in an EEPROM that is exposed over the Pi's DSI I2C port. or at least, that's the idea! we'll see if it works soon :) 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/ -----------------------------------------

if you got a Pi 5 (https://www.adafruit.com/product/5812) and you want to log in or debug without ssh'ing or using a monitor and keyboard - there's now a super fast and easy way to get into the UART console - thanks to the new JST SH 3-pin 'UART' port nestled between the HDMI connectors. Use your Pico Probe (https://www.adafruit.com/product/5699) and connect the 3-pin cable to the 'U' port - the probe board will appear as a COM/serial port, and you can open it up with any terminal program. we love using it for kernel debugging because the connection stays open between reboots and you'll get all messages directly printed, plus the early boot messages...even ones before the firmware is loaded or the display comes up.

for more than a year we've been slowly revising just about every product we make to account for changes in transistors, regulators, diodes, boosters...lots of churn! we're finally up to revision #500 and we're happy to finally get to a product that had to have nearly every component changed: the 3.5" TFT FeatherWing (https://www.adafruit.com/product/3651), the touch driver went from STMPE811 to TSC2007 (https://www.digikey.com/short/v2mf43q9), the screen supplier changed, the boost converter went from FAN5331 to TPS61169 (https://www.digikey.com/short/4zf0d1n2), and we've added a QT port. This demo tests all the hardware functionality - we load a BMP from the SD card, display it on the TFT, then 'draw' on the image with the touchscreen. all is good - we're ready to order the final PCBs!

Our cute 2.1" round 480x480 TFT display (https://www.adafruit.com/product/5792) has a CST826 capacitive touchscreen overlay - different than the other screens that all have Focaltech FT6336U or similar. Thanks to MakerMelissa we now have support in both Arduino (https://github.com/adafruit/Adafruit_CST8XX_Library) and CircuitPython (https://github.com/adafruit/Adafruit_CircuitPython_CST8XX)! We also got a version of our 4" 720x720 display (https://www.adafruit.com/product/5793) with capacitive touch. Unfortunately this one doesn't have the same 'integrated' style where the CTP pads go through the 40-pin connector, bot rather they're on a separate 6-pin 0.5mm pitch tail. Still, it's worth the effort, so we'll make a lil breakout for the touch connector so you can plug it into the QT port.

We saw this call for help over on X, asking for a DigiKey part number for "graphite based thermal pads" (https://twitter.com/ghost_motley/status/1709160119852765465) . These are used to cool down chips on CPUs or GPUs when performing heavy computation. Normally folks use thermal paste but there's also thermal pads that can be used. These are less messy and are more forgiving of gaps or rough spots between the chip and heatsink. One thing to watch for is a lot of 'marketing heavy' modding parts don't publish specs! So while we were not able to find an exact match for 'KryoSheet' - because they purposefully don't say what the thermal resistivity is, we did find some good matches on DigiKey if you want to use graphite thermal pads in your next product.

This week's EYE ON NPI is PIC GmbH's LP Series Reed Switch Chains (https://www.digikey.com/en/product-highlight/p/pic/lp-series-reed-switch-chains), a range of a new kind of liquid level sensor. Not surprisingly, this sensor uses a chain of reed switches and a magnetic float to detect the liquid level in a bucket or tank - we've never heard of this kind of sensor, so we picked one up to check it out! Using a single reed switch for determining liquid level is not new - it's a common way to have a isolatable sensor for food-safe or caustic fluids. Compared to some other liquid level sensors like eTape (https://www.digikey.com/en/products/detail/adafruit-industries-llc/464/8558263) which needs to be 'squeezed' by the liquid to give a continuous resistive reading, or sonar (https://www.digikey.com/en/products/detail/maxbotix-inc/MB7092-100/7896780) which needs to be able to bounce air off, or ToF sensors (https://www.digikey.com/en/products/detail/adafruit-industries-llc/3967/17039169) which can be affected by surface reflectivity/absorption, a reed relay is fully electrically and mechanically isolated. The whole thing can be covered in inert materials and easily cleaned or sanitized. For more details on selecting fluid level sensors check out this DigiKey article (https://www.digikey.com/en/articles/selecting-a-fluid-level-sensor-what-you-need-to-know) The PIC LP Series Reed Switch Chain is made of a thick PCB that is routed down the middle and has tightly packed reed switches (https://en.wikipedia.org/wiki/Reed_switch) soldered one after the other with 1K resistors between each one. A each reed switch closes, the two contacts will measure a resistance that contains all the 'lower' 1K resistors in series. So, say if the first reed switch is triggered the resistance will be 0 ohms, if the next reed is closed the resistance is 1K ohms, all the way up to (n-1)*1K ohms where n is the number of reed switches installed. In order to have the reed switches activate with the liquid level, you'll also need a donut/toroid-shaped magnet float (https://www.pic-gmbh.com/en/level-sensors) which is stocked over at PIC or a generic one can be used if you need particular material. The PCB comes bare and you'll need to put it in a tube that matches your material handling requirements. Also, if you need a longer chain, you can abut them end-to-end and solder them - some mechanical stabilization may also be required. Even though this is designed for liquid float sensing, it could also be adapted to be used as a sliding-platform locator: just watch out that you don't exceed the switch activation lifetime limit - it's a few million but these will be hard to replace if they get damaged. Another nifty side-effect of using reed switches is that they can withstand higher voltages, and since they are not powered, can be wired directly into circuitry that is not ground-referenced and don't care about noise, EMI, static or other common annoyances of industrial automation. There's also some other cool items from PIC to check out at DigiKey (https://www.digikey.com/en/supplier-centers/pic-gmbh), such as SMT reed switches (https://www.digikey.com/en/products/detail/pic-gmbh/PMC-1001TS1015/9687557) which we didn't know existed, and individual reed floats (https://www.digikey.com/en/product-highlight/p/pic/level-sensors) if you don't need continuous level detection. If you want to have a fully mechanically isolated level or position detector that is simple, inexpensive and doesn't require external power, this could work very nicely! And best of all, PIC GmbH's LP Series Reed Switch Chains (https://www.digikey.com/en/product-highlight/p/pic/lp-series-reed-switch-chains) are in stock and available right now for purchase at DigiKey in a range of sizes. Order today and you'll be floating on air... er... liquid, by tomorrow afternoon when DigiKey packs and ships your order immediately.

This week's Great Search is on clicky dome switches! We saw a thread on X (https://twitter.com/RueNahcMohr/status/1716162430265602509) showing off the Snaptron (https://www.digikey.com/en/supplier-centers/snaptron) starter kit - you can pick up a sample box kit for free from (https://www.snaptron.com/free-samples/sample-box/) if you want to try these too. We first saw these on the Pocket CHIP (https://shop.pocketchip.co/collections/frontpage/products/pocket-c-h-i-p-new) as a low cost way to create a key array. One new type we saw is the BL series (https://www.snaptron.com/products/standard-domes/bl-series/) which allows having an LED behind the dome - you'll need a reverse mount LED so it doesn't get crushed. And the DT series which allows two level of actuation (https://go.snaptron.com/DT-Series-White-Paper_V2.0). See the chosen part on DigiKey https://www.digikey.com/short/fvdtp82j

Autumn Lights Festival in Oakland, CA is a long-running and beloved Oakland tradition. It takes place at the Gardens at Lake Merritt every October. This event is a fundraiser for the garden, which is a peaceful sanctuary from the hustle and bustle of the city, right on the shore of the lake. Around 100 LED light artists bring their creations out to Autumn Lights every year. This year, we caught up with Yvette Schindler, who created a giant Connect 4 game using laser-etched acrylic, NeoPixels and arcade buttons. It's a fully functioning game where players can face off with each other by standing on either side of the board and pressing buttons to drop a "piece" wherever they'd like. This was a really popular installation -- people were lined up to play all night long. The game also functions as an art piece, with gorgeous colorful animations that run while no one is playing. It is one of the most beautiful and intuitively interactive use of pixels and Arduino we've seen.

This week's EYE ON NPI will have you doing cartwheels and somersaults, it's the E-Switch RT3301 Series Reverse Tactile Switch (https://www.digikey.com/en/product-highlight/e/e-switch/rt3301-reverse-tactile-switch), a spin on the common 6x6 tactile switch, with reverse mounting for easy assembly and clean design. E-Switch manufactures thousands of different tactile switches that are stocked at DigiKey (https://www.digikey.com/en/products/filter/tactile-switches/197?s=N4IgjCBcoLQdIDGUBmBDANgZwKYBoQB7KAbXABYIBdAXzqA) of various sizes, actuator heights, and mounting styles. In addition to the classic 6x6mm tactile switch, (https://www.digikey.com/short/z0m4fjpp) there's also the SMT 6mm tactile (https://www.digikey.com/short/m7440d0f) that can be pick-and-placed. These buttons have built-in round actuators but they're intended to be used with moulded buttons that have a nub to do the actual pressing: the actuator is just for height. Which explains how the through-hole reverse mount 6mm tactile switch is expected to work (https://www.digikey.com/en/products/detail/e-switch/RT1105AF260Q/15221150) - you're going to definitely need an actuator button since otherwise your fingers will bump into the solder pads! The most curious of these is the reverse-mount SMT tactile switch, which was recently featured by DigiKey (https://www.digikey.com/en/product-highlight/e/e-switch/rt3301-reverse-tactile-switch) in their new products section...and with great timing because just a few weeks ago we published a cool Lisp-powered badge project with a built-in keyboard on the blog (https://blog.adafruit.com/2023/10/10/the-lisp-badge-le-lisp-basdgelife-technoblogy/). To make the key labels nice and large, the author used similar switches with an angled layout for tight packing. The result is a nice clean look on the front, without needing to purchase separate key caps. We'll note that the RT3301's actuator is not as long, so using it with a half-thickness board will get buttons that are flush with the PCB surface. That means it's best for use with separate key caps or overlay...but we're also pretty sure that E-Switch will come out with another version that has longer actuator - just like they have a variety of actuator lengths on the non-reverse 6mm tactile switches. If you want to try the E-Switch's RT3301 Series Reverse Tactile Switches (https://www.digikey.com/short/f71n7z29), they're available right now and in stock at DigiKey for immediate shipment! Order today and you'll have reels or cut tape in hand tomorrow afternoon, a great solution to your complex UI panel design problems.
