RP2040 Trackball Firmware Utilities

Some utilities to help with this project.

Frame Capture and Visualization

The PMW3360 mouse sensor can do full captures of the raw 2D image seen by the chip. These can be grabbed from the firmware by opening the debug USB serial port and running the pmwf command. The output should be pasted into a textfile and can then be visualized using the included visualize_frame.py script.

Data Capture and Visualization

The firmware can also grab a number of data samples from the sensor, by running the pmwd command. The output can then be visualized with visualize_data.py.
