Revision as of 15:27, 1 July 2014

It is fairly easy to include µGFX into your ChibiOS/RT project as ChibiOS/RT uses Makefiles internally as well. The ChibiOS/RT Makefile has to be modified as the following:

  1. Include the µGFX top-level Makefile
  2. Include the driver or board Makefiles that match your hardware
  3. Add GFXSRC to the CSRC variable
  4. Add GFXINC to the INCDIR' variable


Example

The following Makefile is just an example showing how an existing Makefile has to be modified following the steps above. Please DO NOT copy the entire Makfile. The relevant parts have been highlighted.
