NOTE:

At this time my pull request into the main sigrok repo has not been accepted.

Thus mainline releases of sigrok cli and pulseview do not support this repo (or any other way to communiate to a PICO).

The pull request is https://github.com/sigrokproject/libsigrok/pull/181 . I have no ETA when it may be pulled.

So far three other people have managed to combine my pull request into a libsigrok build. If you are on linux it's probably a practical experiment to try. Windows may be much more difficult (my attempts to do so cross compiles have failed). 4GB of RAM is recommended for pulseview builds to avoid disk swap issues. See SigrokBuildNotes.md

I don't have the necessary expertise to build and release sigrok-cli or pulseview executables.

sigrok-pico

Use a raspberry pi pico (rp2040) as a logic analyzer and oscilloscope with sigrok. This implementation uses the pico SDK CDC serial library to communicate with sigrok-cli/pulseview through a sigrok driver.

Directories:

pico_pgen is a simple digital function generator useful for creating patterns to test.

pico_sdk_sigrok is the pico sdk C code for the PICO RP2040 device.

The latest libsigrok code exists as a fork at https://github.com/pico-coder/libsigrok
