  1. Achieving ~5.4Mbit/s USB throughput from my #pico2 device (Full Speed) to python host on windows. Not sure if I'll be able to get more out of it with this setup... #USB #data #throughput #raspberry

  3. While probing a GPIO pin on my oscilloscope, I noticed it toggled between 2.4V and 3.3V. Using another reference pin, toggling at exactly the same time swinged correctly between 0V and 3.3V

    I think I might have damaged a pin on my #rp2350 :( #debugging #signals #embedded #pico2

  5. Looking to turn my #Pico2 in a rudimentary #oscilloscope. Have been checking the ADC's samplerate and tried measuring an ultrasonic distance sensor's echo pulse. Not quite there yet, USB throughput is still a limiting factor.

  6. Little job this lunchtime, flashing #micropython to a load of #RPI #pico2 for the kids creative code club I'm running tomorrow. #raspberrypi

  7. I made "Greggs Roulette", an app to decide what tasty treat to eat from Greggs!
    I used the new Tufty 2350 from Pimoroni, it has a lovely bright screen, great case and a powerful #RaspberryPi #RP2350 SoC (the same as the #Pico2) with Wi-Fi and onboard LiPo power!

  8. Stepper up and running. Set to default 1/8 microstepping, with the MCU sending a step every 100_000 ns.

    Was having trouble with lower step delay--my quick review indicates the typical step low and step high time can be as small as 100 ns. I need to review the datasheet more in depth. Maybe I don't understand the possible interaction with microstepping or some other functionality.

  10. Correct result came a bit faster then expected! Step response measured through RP2350 ADC from 3V3 to Ground. The transition in between is due to the ADC pin being floating for a brief moment in time #pico2 #embedded

  11. ADC readouts on the #pico2 are coming together. Plot below for the visualization of MSB of the adc output (4 bits). Switching input from 3V3 to GND.

  12. Spent some time getting a usb bulk data stream working on a Raspberry Pico 2W using TinyUSB.

    Biggest hurdles were device/configuration descriptor and realizing tud_task() needs to be called frequently.

  13. Debugging the RP2350’s ARM + RISC-V cores was… an adventure
    - GDB refusing to launch
    - Too many breakpoints on RISC-V
    - Switching architecture not as seamless as I thaught for debugging

    You can read about it here: embeddedjourneys.com/blog/rpi-

  14. Good to know as well that I only have 4 breakpoints available on my pico 2 with RISC-V, while I seem to have a lot more available when using the ARM architecture. #pico2 #RPIDebugProbe #debugging

  15. Took some time to figure out how to switch between ARM and RISC-V architectures on my RPI Pico 2 and to keep my Raspberry Pi Debug Probe functional! Finally! Blog post incoming! #arm #riscv #pico2 #rp2350

  28. Anyone else have a back log of micro-controller projects that are waiting on tariffs to clear up? #ESP32 #Pico2 #TrumpTariffs

  29. Very nice new gadget, the #PicoCalc by #ClockworkPi! 🤩 Got mine a few days ago and am currently learning a lot about how it works. Documentation is a bit sparse, currently. You have to study many forum posts on forum.clockworkpi.com, there's currently no "gettings started" guide. – A bit disappointing: No Python (neither Micro-, nor Circuit-) out of the box. But folks (not ClockworkPi) are working on it. – If you're into Forth: it's already there. #RaspberryPi #Pico #Pico2 #MMBasic

  30. Мурмулируем Mac 128K

    Есть у меня хобби: портирование всякого-разного под Мурмулятор , и попалась мне на глаза реализация одного из самых древних "маков" - Macintosh 128K: github.com/evansm7/pico-mac . - Это же почти готовая прошивка под Мурмулятор, - подумал я. Основное отличие - другая распиновка VGA, да и реализация периферии немного отличается. После того, как в профильном чате ТГ канала этот эмулятор тоже упомянули пару раз, как кандидата на портирование, взялся за него и я.

  34. This is a curse of compromises but at least I now have options. Using PSRAM , I converted my bouncing balls simulation to run at the full screen resolution of 480x480 with my anti-aliasing code. Graphics look beautiful, but screen refresh rate dropped to 10 fps due to the time taken to copy the drawing buffer in PSRAM to the screen buffer in the main RAM. Compare this to using a 240 x 480 resolution for buffers all in main RAM where I get 56 fps.

  36. has anyone coaxed the into using PSRAM with embassy-rs? I couldn't find an obvious example in my searches this morning. I did find some arduino startup code that I can probably translate and adapt, but if someone has already done the heavy lifting, that would save me some effort!

  38. @rpimag I did a bit more work on my UART booting Flashless Picos. On the end of each "pico" there's an I2C port for the I/O expander (used to reset/setup the RP2350A to boot from UART) and a UART port to send the bin file/communicate after boot. The Pico2 in the PicoUART6 is running CircuitPython using Adafruit_CircuitPython_PIO_UART for the non-hardware UARTs.

  39. Many people wanted a RESET button on their Pico but I decided to make one without buttons 🤣 .

    It currently has no FLASH/PSRAM and boots over UART (3-pin at the bottom) or you can upload a UF2 over USB. The I2C expander towards the bottom (4-pin STEMMA QT) can twiddle the BOOTSEL, SD1 and RUN pins.
