trace-xyyx

Simple C Tracing example, for x86 and raspberry pi pico.

Steps to build it:

1. export PICO_SDK_FETCH_FROM_GIT=true or export PICO_SDK_PATH = <path>
2. mkdir build
3. cd build
4. cmake ..
5. make -j 8
6. then copy trace-xyyx.uf2 to your pico-pi for fun!

To add a trace point, edit the metadata file. Then run xxd -i metadata > metadata.h to override the metadata.h file.

This needs more work, it is still non-functional.

To test on x86, run gcc ctf.c xyyx.c -o xyyx.c
