Pixycam startup program

Hello i would like to edit built in pixy program pan/tilt demo to move 2 servos (left/right wheels) instead of pan/tilt platform.
Is that possible? Which file in ‘src/device/main_m4/src/’ is doing pan/tilt demo thing in PixyMon?

Hello Dawid,
Sure, it should be possible The file is ptprog.cpp, but this demo is running as part of the Pixy firmware. It’s probably difficult to modify the Pixy firmware (requires a special compiler, etc.) There is another way to run a pan/tilt demo through an Arduino, by running the Arduino pan/tilt demo. The advantage of this demo is that it’s easier to change, compile, etc. It would be a good start. Here is the source:
