Is this project intended to be built under "PlatformIO" - or in Arduino?

@maxgerhardt :

I'm still a bit confused wrt "PlatformIO", and I was just getting started with Arduino - so you are moving a bit fast for me to keep up... please bear with me.

I gather from comments you've made that the code in this repo. supersedes the code you posted here - or perhaps it's more correct to say that code was not intended to be built in the Arduino environment? ... Have I got that correct so far?

Also, I gather the code here in this repo is intended to be used in the "PlatformIO" environment... is that correct?

I'll just pause a moment here to say I'm willing to try anything, but my first preference would be to have something I can use in the Arduino-Pico environment. You made some comments here that suggest I may be able to do this in the Arduino-Pico environment:

It should work the same in the Arduino IDE if you open the main.cpp as main.ino in it, and set the USB stack to "None". I uploaded using a Debugprobe on Pico (CMSIS-DAP) and measure the VBUS line with my Nordic PPK2's Ammeter, which was fed externally by the Debugprobe's VBUS.

• I've no idea what CMSIS-DAP is.
• I do have a Debug Probe.
• I do not have a PPK2 ammeter, and will forego making current measurements for the time being... I just want to see some working code!

All that said, can you walk me through what I need to do to get your code working and uploaded to the Pico from Arduino-Pico using the standard USB connection?

You can flash another Pico with the https://github.com/raspberrypi/debugprobe/releases firmware and it will become a CMSIS-DAP device, which is a standardized debugging adapter. It can flash another Pico via its SWD pins, as explained in.

A "Debug Probe" is running the debug probe firmware, and thus is a CMSIS-DAP.

You can upload the firmware via the standard USB connection. Just note that the firmware itself does not open a USB serial port, so it will not print anything, it will just go to sleep when its being sent a UART character. So, to be able to test anything, you would very much need a device which can send that UART data; which is what a debug probe can also do. (it's a dual USB device: one CMSIS-DAP interface, one USB-to-serial adapter)

Lots of this is documented in https://arduino-pico.readthedocs.io/en/latest/platformio.html and the therein linked docs.

You do not need PlatformIO for this. You can copy paste all needed source files into one directory, rename main.cpp to main.inoand open that in the Arduino IDE and flash it. However, the files in this project are meant as a PlatformIO project.

Thanks @maxgerhardt - I'll try this asap :)
