This page documents a handy automated process for converting keyboards, as well as documenting the manual process if you'd like to make use of Proton C features that aren't available on Pro Micros. - -## Automatic Conversion - -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: - -```c -#ifdef CONVERT_TO_PROTON_C - // Proton C code -#else - // Pro Micro code -#endif -``` - -If you get errors about `PORTB/DDRB`, etc not being defined, so you'll need to convert the keyboard's code to use the [GPIO Controls](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. - -| Feature | Notes | -|-------------------------------------|------------------------------------------------------------------------------------------------------------------| -| [Audio](feature_audio.md) | Enabled | -| [RGB Lighting](feature_rgblight.md) | Disabled | -| [Backlight](feature_backlight.md) | Forces [task driven PWM](feature_backlight.md#software-pwm-driver) until ARM can provide automatic configuration | -| USB Host (e.g. USB-USB converter) | Not supported (USB host code is AVR specific and is not currently supported on ARM) | -| [Split keyboards](feature_split_keyboard.md) | Partial - heavily dependent on enabled features | - -## Manual Conversion - -To use the Proton C natively, without having to specify `CTPC=yes`, you need to change the `MCU` line in `rules.mk`: - -``` -MCU = STM32F303 -BOARD = QMK_PROTON_C -``` - -Remove these variables if they exist: - -* `BOOTLOADER` -* `EXTRA_FLAGS` - -Finally convert all pin assignments in `config.h` to the stm32 equivalents. - -| Pro Micro Left | Proton C Left | | Proton C Right | Pro Micro Right | -|-----------|----------|-|----------|-----------| -| `D3` | `A9` | | 5v | RAW (5v) | -| `D2` | `A10` | | GND | GND | -| GND | GND | | FLASH | RESET | -| GND | GND | | 3.3v | VCC <sup>1</sup> | -| `D1` | `B7` | | `A2` | `F4` | -| `D0` | `B6` | | `A1` | `F5` | -| `D4` | `B5` | | `A0` | `F6` | -| `C6` | `B4` | | `B8` | `F7` | -| `D7` | `B3` | | `B13` | `B1` | -| `E6` | `B2` | | `B14` | `B3` | -| `B4` | `B1` | | `B15` | `B2` | -| `B5` | `B0` | | `B9` | `B6` | -| `B0` (RX LED) | `C13` <sup>2</sup> | | `C13` <sup>2</sup> | `D5` (TX LED) | - -You can also make use of several new pins on the extended portion of the Proton C: - -| Left | | Right | -|------|-|-------| -| `A4`<sup>3</sup> | | `B10` | -| `A5`<sup>4</sup> | | `B11` | -| `A6` | | `B12` | -| `A7` | | `A14`<sup>5</sup> (SWCLK) | -| `A8` | | `A13`<sup>5</sup> (SWDIO) | -| `A15` | | RESET<sup>6</sup> | - -Notes: - -1. On a Pro Micro VCC can be 3.3v or 5v. -2. A Proton C only has one onboard LED, not two like a Pro Micro. The Pro Micro has an RX LED on `D5` and a TX LED on `B0`. -3. `A4` is shared with the speaker. -4. `A5` is shared with the speaker. -5. `A13` and `A14` are used for hardware debugging (SWD). You can also use them for GPIO, but should use them last. -6. Short RESET to 3.3v (pull high) to reboot the MCU. This does not enter bootloader mode like a Pro Micro, it only resets the MCU. |
