RPi Pico Probe

This firmware implements an CMSIS-DAP v1 and v2 compatible probe on the RPi Pico.

It's currently using a bit-banged driver, so expect max speeds around 2 MHz.

Current pinout

You can change this to whatever you want in setup.rs.

PinDescription
GPIO13nRESET
GPIO14SWDIO
GPIO15SWCLK

Building

You can build the project and generate a .uf2 file as follows:

# Install elf2uf2-rs
cargo install elf2uf2-rs

# Build the ELF without logging
DEFMT_LOG=off cargo build --release --bin pico-probe 

# Generate .uf2 file
elf2uf2-rs target/thumbv6m-none-eabi/release/pico-probe pico-probe

Start the Pico in bootloader mode and drop the pico-probe.uf2 file to it, done!
