The Great Search - 1.1V Mini Regulator

For our RP2350 Bones boards, we might not use the built-in DC/DC converter on some variants—and it's not required! We could use an external 1.1V regulator, if it can source 200mA. This affects low-power usage, but that might not be important in some cases. If we can source a tiny regulator, this could shave a bit of space off.

Desk of Ladyada – RP2350 Bones Day

New RP2350 chips are here, and we're building fresh "Bones" boards—starting with the Adalogger RP2350. We also fixed Sparkle Motion's power issue and designed a Stick version. Plus, we're exploring tiny 1.1V regulators to optimize future boards.

EYE ON NPI - Infineon Technologies PSOC Control C3 Microcontroller Line

This week's EYE ON NPI is Pretty Sweet Of Course! It's the Infineon Technologies PSOC Control C3 Microcontroller Line (https://www.digikey.com/short/8cw3wpp8) a souped-up microcontroller that is a perfect choice for engineers who need to do some motor control while also managing buttons, LEDs, displays, and other product requirements all on one chip. With a the high-speed ADCs on board, you can manage your BLDC motors and handle the feedback loop in firmware for dynamic tuning without the expense of a specialized co-processor. The PSOC Control C3 series comes in two flavors, the Entry and Main line chips (https://www.infineon.com/cms/en/product/microcontroller/32-bit-psoc-arm-cortex-microcontroller/32-bit-psoc-control-arm-cortex-m33-mcu/psoc-control-c3m/). Both are based on the Arm Cortex M33 which means you know that your CMSIS-based code will be an easy compile and you can use existing pre-compiled libraries. The M33 line is an upgrade to the M3 and M4, giving you the same or better clock speeds and FPU/DSP commands you get with the M4 plus TrustZone and better power efficiency. The Entry line runs at 100MHz, with max 256k Flash 64K SRAM, 10-bit DAC, a 6 MSPS 12-bit ADC, 16 x 16-bit + 4 x 32-bit TCPWMs and a "CORDIC math coprocessor". The Main line can run at 180MHz, same Flash/SRAM and TCPWMs, and has a 12 MSPS ADC plus 4-channel HRPWM with less than 100ps resolution. Both come in 48 and 64 pin TQFP/QFN varieties, the Main line also has an 80-pin version. (There will also apparently be a Performance line, so far un-announced, which may offer more memory / higher frequency). Both have FPU/DSP support, so you'll be able to process the 6 or 12-MSPS ADC data quickly. And the CORDIC processor (https://en.wikipedia.org/wiki/CORDIC) optimizes trig functions like sin/cos/tan/ln so you don't need lookup tables for performing these floating point calculations. These are particularly useful when handling motor motion calculations since they are often sinusoidal and we need to convert to-and-from the ADC measurements to the precision PWM timers. There's a huge selection of Arm processors out there, but the PSOC Control C3 has the best peripherals for motor control: it's rare to see 12MSPS 12-Bit ADC plus so many 16-bit and 32-bit timers with high-speed PWM. The CORDIC co-processor especially will make managing BLDC or Stepper motors a breeze. Plus you still get all the peripherals you would expect of a microcontroller: I2C, UART, SPI, CAN bus, DAC, IRQs, and lots of GPIO. That means you can handle all the other stuff your product has to do while also managing the motor in the background, saving you lots of space and money in BOM costs and fewer integration woes when trying to communicate between a main processor and a motor-control co-processor. The KITPSC3M5EVK eval board (https://www.digikey.com/en/products/detail/infineon-technologies/KITPSC3M5EVK/25880112) is in stock right now if you want a ready-to-go kit at a good price. It comes with 'Arduino shield compatible" pinouts plus a USB / debug interface, and MikroBus connector for expansion. You can also pick up just the bare chip - for example the PSC3M5FDS2ACQ1AQSA1 (https://www.digikey.com/short/8cw3wpp8) is a fancy version with 256K of flash, the 12 Msps ADC, and hall encoder in a TQFP-64 package. It's in stock now at DigiKey for immediate shipment! Order today and you can have a powerful microcontroller with excellent motor feedback control in your hands by tomorrow morning.

Desk of Ladyada - Slow Sunday Pokes

This week was slow for hardware development—we were getting over being under the weather. But we did poke a little at a PCM5122 breakout board (https://www.digikey.com/short/fnf9t0b1). This chip can do software or hardware control of I2S signals and is preferred by folks who want something a little nicer than the PCM5102 (https://www.adafruit.com/product/6250). We also wrapped up our design for the 8x solenoid driver board—the biggest update is adding indicator LEDs. Lastly, we got our prototypes for the "USB CC Fixer" adapter, which we mostly made so we could charge a really annoying baby monitor, but probably other folks will want to buy it, too. ----------------------------------------- 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/ -----------------------------------------

The Great Search - 5W+ Class D I2S Amp

We've been putting a lot of I2S DACs in the shop, like the PCM5102 (https://www.digikey.com/short/fnf9t0b1) and TLV320DAC3100 (https://www.digikey.com/short/wj2d8w2h), and working on more like the PCM5122 (https://www.digikey.com/short/fnf9t0b1). What we'd really like is an I2S speaker amplifier that is preferably stereo and can do more than 5W—e.g., a cross between the MAX98357 (https://www.adafruit.com/product/3006) and MAX9744 (https://www.adafruit.com/product/1752).

EYE ON NPI - EYE ON NPI - Raspberry Pi RP2350A and RP2350B Microcontrollers

For this week's EYE ON NPI, we'll Hazard a guess that you'll be excited to see the Raspberry Pi RP2350 chip available for purchase at Digi-Key for integration into your next design. We've been working with this chip for a few months and it's quickly becoming our favorite Arm Cortex chip, with fun peripherals and a well-supported toolchain. It also is one of the first mass-produced RISC-V chips: one that you can buy and start using for trying out RISC-V development without the 'risc' of worrying you may have picked the wrong core. Available in two chip sizes and with a boost in performance and peripherals, the RP2350 (https://www.digikey.com/short/mzpjhptm) represents a big upgrade to the RP2040 (https://www.digikey.com/en/products/detail/raspberry-pi/SC0914-13/14306010) that you've seen take over the microcontroller world over the last 4 years. Raspberry Pi is famous for their single board computers (https://www.digikey.com/en/products/filter/single-board-computers-sbcs/933) so much so that they created a full market for sub-$100 all-in-one PCs. The big disruption we feel they brought to the market was the creation of a hackable and open-source ecosystem with good main-line OS and driver support. With well-written documentation and up-to-date Linux software, purchasing a Pi meant you got to join in with a community that was having fun, not struggling with compiling out-of-tree kernel modules and closed-source firmware. So in 2021 when they announced the RP2040, folks were interested: could a SBC maker design low power silicon? Turns out, yes! The RP2040 was a fun dual-core 133 MHz Cortex-M0+ processor, with 264K of SRAM, with a satisfying collection of peripherals: USB, ADC, UART/SPI/I2C, PWM, DMA and timers plus the nifty PIO state machine (https://www.raspberrypi.com/news/what-is-pio/). The killer feature, though, was the price: at $1 a chip, and tons of availability with an on-going chip shortage, the RP2040 won our hearts and soldering stations! Three years later, Raspberry Pi is back with a sequel: The RP2350A (https://www.digikey.com/en/products/filter/microcontrollers/685?s=N4IgTCBcDaIE4AcwGYCsAGAgiAugXyA) and RP2350B (https://www.digikey.com/en/products/filter/microcontrollers/685?s=N4IgTCBcDaIE4AcwGYCsAGAQiAugXyA) two variants of an upgrade chip that keeps what was great about the '2040 but with some boosts. First up, the core was upgraded from dual Cortex-M0's to the M33: this means you get an FPU and better low-power performance, plus TrustZone security. The core is spec'd for 150MHz but we've overclocked it to 264MHz without too much complaint. You also have the option to get dual RISC-V cores (https://riscv.org/) instead. SRAM was also bumped: from 264K to 520KB. This is great for running interpreted languages like MicroPython (https://micropython.org/) or CircuitPython (https://circuitpython.org/). Like the original, the RP2350 does not have any built in FLASH memory. Instead, you will need to wire it to a QSPI flash memory chip (https://www.digikey.com/short/80t4zt5t). This way you can pick from 1 MBytes to 16 MBytes whatever your code size needs. This new chip adds the ability to wire in PSRAM (https://www.digikey.com/short/d8033bfw) to the same QSPI bus plus an extra chip select. This is not going to be nearly as fast as on-chip SRAM, but it's great when you want large working memory that the chip will manage for you: by configuring it in the CMakefile, you 'magically' get a huge area you can malloc. Another improvement is in the number of PIO blocks: the original had 2, the RP2350 has 3. The two biggest new features we found are the new HSTX peripheral and the 80-QFN RP2350B (https://www.digikey.com/en/products/filter/microcontrollers/685?s=N4IgTCBcDaIE4AcwGYCsAGAQiAugXyA) variant. HSTX stands for High Speed Transmission and its a high-speed peripheral that can drive 8 output lines - note that it's output only! There's a few possible use cases, but the core reasoning is that this lets you control a DVI display directly from the chip using just the DMA and internal memory without requiring overclocking, PIO, or an extra core. Note that the built in SRAM limits the size of the display if you want to have a video buffer: you can do 320x240 @16bpp or 640x480 @8bpp but, still! Second, if you found the original QFN-60 a bit constraining in terms of GPIO, the QFN-80 'B' version has 20 extra GPIO available for just 10 cents more. If you've been doing grabby-hands in hopes of getting a reel of RP2350 chips into your next design: today is your lucky day! Digi-Key has these chips in stock RIGHT NOW for immediate shipment. You can get a reel of either A or B type chips, with cut tape individual components coming shortly. Both types are great, but recently we've been having a lot of fun with the roomy B type (https://www.digikey.com/short/mzpjhptm), with the extra GPIO. Order today and you can start integrating the tren

Glowing Hair Flowers with Adafruit n00ds: Flexible LED Filament Project

Full tutorial: https://learn.adafruit.com/glowing-hair-flowers-with-n00ds/overview Light up your hair with these beautiful iridescent glowing hair flowers. The magical light comes from Adafruit n00ds: a fun, flexible noodle-like LED filament. These little noodles are jam-packed with LEDs and look a bit like EL wire, but with no need for an inverter. They are available in a variety of colors and lengths so you'll be able to find just the right n00d for your project. This is a fun beginner project that requires a little bit of tricky soldering but no coding or software. Just connect the n00ds to a coin cell battery breakout and they will light up and glow. Adafruit n00ds come in a variety of colors and lengths. We also have them in single-ended or double-ended variety. The double-ended variety are a bit easier to solder to: solder a wire to each end. The single-ended variety have both leads on one end, which is perfect for some projects where you don't want to have to double back to the battery, but these are wicked hard to solder to. For these hair flowers I used the 300mm single-ended n00ds in red, blue, and warm white. https://www.adafruit.com/product/6150 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/ -----------------------------------------

The Great Search - Extra-Tall 6mm Tactile Switches

For our next design of the Fruit Jam board, we want to design a top plate that will let the header strip and switch poke out. This means we also have to choose buttons that will be able to poke out, so that they can be pressed when the plate is in place. Measuring the header height, it's 8.5mm tall, so we want 6mm x 6mm SMT tactile switches with more than 8.5mm actuator height from PCB (but no more than 11mm). Let’s see what is available at Digi-Key!

For our next revision of Fruit Jam (https://www.adafruit.com/product/6200), we want to add an onboard speaker to provide some sound beeps and boops. The amplifier we're using can drive 4 or 8-ohm speakers, up to a couple watts—but we're not expecting hi-fi sound here. Most important is something that is solderable into the PCB so that it is an "all-in-one" setup. It also has to be less than 0.8" in diameter to fit into the unpopulated area left over on our design.

Testing Dark Castle with audio on the RP2350 Fruit Jam 🕹️🏰

Jepler spent a bunch of time this week working on getting audio working on the pico-umac port https://github.com/jepler/pico-mac/tree/rp2350-fruitjam to Fruit Jam https://www.adafruit.com/product/6200 . Audio on the hardware we're emulating is pretty straightforward: every scanline of the video generator also pops out one byte of PWM data. We have 370 horizontal lines—352 visible and 18 during the vsync—and a 60.15 Hz refresh rate for 22.255 KHz audio approximately. That data is written to $1FD00 http://www.mac.linux-m68k.org/devel/plushw.php . That data is being piped over I2S to the MAX98357 https://www.adafruit.com/product/3006 and to a speaker for now. So, of course, the first thing we have to try out is Dark Castle https://archive.org/details/mac_DarkCastle_1_2 : famous for great audio and being a surprisingly hard game to play! The audio sounds really good though :) 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/ ----------------------------------------- #marchintosh #apple #diy

EYE ON NPI - Boréas Technologies' BOS1931 High-Efficiency Piezo Driver

This week's EYE ON NPI is trendy and buzzy, it's Boréas Technologies' BOS1931 High-Efficiency Piezo Driver (https://www.digikey.com/en/product-highlight/b/boreas/bos1931-high-efficiency-piezo-driver). This chip is a compact way to add powerful high-voltage piezo drive to any product, combining three chips: power supply, waveform generator and driver. With a complete I2C/I3C interface that you can connect to any microcontroller/processor it's the most advanced all-in-one piezo driver we've seen! Piezo (https://en.wikipedia.org/wiki/Piezoelectricity) discs are multi-use devices that convert mechanical movement to electrical signal, and vice-versa. They're most often seen as electrical-to-mechanical converters such as piezo beepers (https://en.wikipedia.org/wiki/Piezoelectric_speaker) where an AC signal, usually 3 to 6V peak-to-peak square wave, is applied across the disk. The frequency of the wave is translated into a sound frequency. It doesn't have the same fidelity as a magnetic speaker but its much thinner, less expensive for the component and driving circuitry, and for 2 to 4 KHz beeps it's just fine. Piezos can also be used the opposite way, where mechanical stress on the crystal is translated into an electrical signal. In this way it can be used as a switch or force sensor (https://en.wikipedia.org/wiki/Piezoelectric_sensor), again usually a few microamperes' worth of current is generated. For these basic uses, your standard microcontroller pin, or at best an H-Bridge will work just fine: you can drive piezo's differentially to get more Vpp across the disc but essentially we're still talking about only a few Volts. There are some times when you want to make a piezo really 'loud' - that is, putting 100+ Volts across the crystal to generate a big mechanical response. This is often not for audible use cases, after all if you wanted to do that you'd just use a magnetic speaker (https://www.adafruit.com/product/1732) that can get to many many Watts of output efficiently. FYI there's two variants of the chip: the BOS1931 (https://www.digikey.com/short/w9tz9tbj) and the BOS1921 (https://www.digikey.com/short/nnb0r29r). The '31 can only do piezo driving. The '21 can do sensing as well as driving, so it can be used for force-feedback products. In this particular EYE ON NPI we'll just be chatting about the driving capabilities of both. So, while we can do basic sensing/beeping with a few Volts - when we want to have significant motion for blasting sonar or moving fluid around we can only increase the movement by increasing the peak-to-peak voltage. Each piezo you buy will have a voltage rating - and you will need a boost converter to generate that peak-to-peak. For the BOS19 series of chips, you can get +-95V so 190Vpp max, which will drive any piezo you find, and you only need 3~5V input thanks to a built-in DC/DC boost converter. Boréas didn't stop there. Not only do you get a booster, but also a full waveform manager with I2C/I3C control. You can can fill up a FIFO buffer with waveform bytes to generate different shapes. There's a sine generator you can control with an envelope creator. Or, you can piece together waveform shapes for different pump/haptic behavior, giving you the customizability of a byte-wise waveform generator with the simplicity of a sine generator. They even have a Haptics Studio' to help you craft the waveform you want (https://www.boreas.ca/pages/haptic-studio). The BOS1931 (https://www.digikey.com/short/w9tz9tbj) and the BOS1921 (https://www.digikey.com/short/nnb0r29r) come in two packages: an easy-to-layout-and-solder QFN and a tiny-and-advanced BGA. Both have the same core so just pick whether you need simplicity or small size. Since its a pretty serious boost converter and driver - the piezo connects directly to the output pins - you'll need to watch your layout. Check the datasheet for their recommended setup to make sure you don't have excessive power loss or EMI. IF you want to get started quickly, the BOS1921-KIT-B01 (https://www.digikey.com/short/v9hn8mcd) evaluation board will let you use their configuration software to quickly determine how your piezo actuator or sensor response to the waveform generator and booster before you start laying out the components on a prototype PCB. If you have some serious piezo-ing you need to get moving, the Boréas Technologies' BOS1931 High-Efficiency Piezo Driver (https://www.digikey.com/short/w9tz9tbj) can do everything from voltage generation, waveform shaping, and differential driving. And best of all it's in stock right now at Digi-Key for immediate shipment! Order today and DigiKey will pick and pack your order in an instant so that you can be vibin' with your fancy new piezo controller by tomorrow afternoon.
