My cmake files for use the gcc-arm-embedded toolchain (gcc/g++) and the mbed libraries together.

Everything is tested on Mac OS X at the moment only with the LPC1768 mbed devices. As soon as i get other devices, i will integrate the other processors and vendors too. If you like too have additional targets added you can either send:

  • a pull request with the needed addition
  • a board, i will add support as soon as possible
