#pico2 — Public Fediverse posts

Adding those male headers on the #breadboard next to my #pico2, greatly facilitated probe access to the pins for my #oscilloscope measurements!

Published my first product on
@Gumroad: A Pico 2 #USB Streaming Guide - achieve 5.1 Mbps USB throughput from a #pico2 with #tinyusb to a python application on a windows host.

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

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

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.

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

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!

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.

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

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.

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.

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: https://embeddedjourneys.com/blog/rpi-pico-debugging-multi-core-arm-risc-v/

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

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

The #MZ700 emulation for the #Pico MZ is nearly finished! Documentation to write and update, plus testing on #RC2014 cards and #Pico2 hardware left to do. Hoping to have version 3.0.0 released by the end of the month. #RetroComputing

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
