RP 2040 - PIO programming in Arduino IDE on linux
I've got a few Picos, I'd like to try programming PIO. Quick search shows mostly micropython tutorial (which are useless to me), or 1-3 years old tutorial for windows workflow.
Can anyone point me to a good tutorial for programming PIOs on linux within Arduino IDE preferably, or explain how to get started?

ok, I'll try to figure it out later... Right now I'm tired.
It's mor or less dead any ways last post was last month..
Doubt anything good will come of it.

I finally got it working... Here's the process:
- Add
https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json to preferences/board manager URLs
- Go to board manager, and search for Raspberry Pi Pico/RP2040 by Earle F. Philhower, III and install it.
- Find the location of your arduino packages, mine is at: ~/.arduino15/packages
- Copy "pioasm" executable from: packages/rp2040/tools/pqt-pioasm/4.1.0-1aec55e -> your project folder, right beside your .pio file. (beware that "4.1.0-1aec55e" directory name may change upon update...)
- To generate the header file, run: ./pioasm FileName.pio FileName.pio.h from within your project folder.
I could write data to the state machine, and returned it flipped, but I could not get the LED to blink yet...
not sure why, but maybe I'm just too noob when it comes to assembly...Also here are some resources for good measure:
