Quick start

To install the raspberry pi pico support and sigrok decoders do:

pip install pysigrok-hardware-raspberrypi-pico

Once installed you can list supported hardware, formats and decoders with:

$ pysigrok-cli -L

Supported hardware drivers:
  raspberrypi-pico      RaspberryPI PICO

Supported input formats:
  srzip srzip session file format data

Supported output formats:
  bits  ASCII rendering with 0/1

You'll need to install the sigrok-pico code onto your RP2040. The source is on Github and the uf2 to install is as well.

To find the CDC device for the RP2040:

$ pysigrok-cli --list-serial

Available serial ports:
  /dev/ttyUSB0 - CP2102N USB to UART Bridge Controller
  /dev/ttyACM2 - Pico - Board CDC
  /dev/ttyACM1 - nRF52 Connectivity
  /dev/ttyACM0 - Feather M0 Express - CircuitPython CDC control

To capture to a sigrok .sr file:

pysigrok-cli -d raspberrypi-pico:conn=/dev/ttyACM2 -C D16,D17,D18,D19 --samples 10 -c samplerate=10000000 -o test.sr

Open test.sr in PulseView.
