As of 28 Sept 2023 this pull request has been merged into mainline sigrok (sigrokproject/libsigrok#181) It is highly recommended to install from https://sigrok.org/wiki/Downloads
Please start with the Getting Started page : https://github.com/pico-coder/sigrok-pico/blob/main/GettingStarted.md ///////////////////////////////////////////////////////////////// Building this repo: Bbuilding is not recommended, but some people insist on trying.....)
I once did a cross compile of PulseView for windows. The instructions and installer are left in place for historical reference, they are likely out of date. Instructions to download my build are here https://github.com/pico-coder/sigrok-pico/blob/main/pulseview/Readme.md Again, please use the main sigrok installer.
For linux, many 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. 4GB of RAM is recommended for pulseview builds to avoid disk swap issues. See SigrokBuildNotes.md
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.
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
