| # Converting a board to use the Proton C
 | |
| 
 | |
| If a board currently supported in QMK uses a Pro Micro (or compatible board) and you want to use the Proton C, you can generate the firmware by appending `CONVERT_TO_PROTON_C=yes` (or `CTPC=yes`) to your make argument, like this:
 | |
| 
 | |
|     make 40percentclub/mf68:default CTPC=yes
 | |
| 
 | |
| You can add the same argument to your keymap's `rules.mk`, which will accomplish the same thing.
 | |
| 
 | |
| This exposes the `CONVERT_TO_PROTON_C` flag that you can use in your code with `#ifdef`s, like this:
 | |
| 
 | |
|     #ifdef CONVERT_TO_PROTON_C
 | |
|         // Proton C code
 | |
|     #else
 | |
|         // Pro Micro code
 | |
|     #endif
 | |
| 
 | |
| Before being able to compile, you may get some errors about `PORTB/DDRB`, etc not being defined, so you'll need to convert the keyboard's code to use the [GPIO Controls](internals_gpio_control.md) that will work for both ARM and AVR. This shouldn't affect the AVR builds at all.
 | |
| 
 | |
| The Proton C only has one on-board LED (C13), and by default, the TXLED (D5) is mapped to it. If you want the RXLED (B0) mapped to it instead, add this like to your `config.h`:
 | |
| 
 | |
|     #define CONVERT_TO_PROTON_C_RXLED
 | |
|

| ## Feature Conversion

| 
 | |
| These are defaults based on what has been implemented for ARM boards.
