ELRSController — Debug logging

This project uses a compile-time debug flag to enable Serial debug output.

How to enable debug logging with PlatformIO

Add the following to the environment you build for in platformio.ini:

Note: Replace your_env with the actual environment name you use in your platformio.ini file (e.g., [env:leonardo]).

[env:your_env]
build_flags = -DDEBUG_LOG

When DEBUG_LOG is defined the code will initialize Serial and DEBUG_PRINT/DEBUG_PRINTLN macros will output to Serial. When DEBUG_LOG is not defined the macros compile to no-ops and there will be no Serial output.

Caution

Some boards (especially those that emulate USB HID like a joystick) have conflicts between the Serial USB interface and HID. Only enable debug Serial during testing.
