EYE ON NPI - EYE ON NPI - Raspberry Pi RP2350A and RP2350B Microcontrollers 10:18

1 day önce10:18

10:18

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 trendiest new silicon into your new PCB assembly by tomorrow afternoon.…

Glowing Hair Flowers with Adafruit n00ds: Flexible LED Filament Project 4:20

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 6:29

4 gün önce6:29

6:29

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!

The Great Search: 8 Ohm PC Pin Mount Speaker 8:14

8:14

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. Let's see what we can find at DigiKey!

Testing Dark Castle with audio on the RP2350 Fruit Jam 🕹️🏰 2:14

5 gün önce2:14

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…

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.…

Browsing HyperCard stacks on our RP2350-based Fruit Jam 🍏📂 With a little more tweaking, we've got a nice big 12MB disk image loading into our Pico-Mac port https://github.com/jepler/pico-mac/tree/rp2350-fruitjam to the Fruit Jam https://www.adafruit.com/product/6200 — that 16MB of internal flash is coming in super useful now! That means not only can we run System 6 but also install some nice software like HyperCard https://en.wikipedia.org/wiki/HyperCard ! As kids, we loved playing and making HyperCard stacks, so it's neat to see that we can still navigate the classics on an RP2350. Many stacks have music or sound effects, so we'll revisit these once we get audio playback working.
