* Another possible use is for centralized threads memory management, * terminating threads can pulse an event source and an event handler * can perform a scansion of the registry in order to recover the * memory. * @pre In order to use the threads registry the @p CH_USE_REGISTRY option * must be enabled in @p chconf.h. * @{ */ #include "ch.h" #if CH_USE_REGISTRY || defined(__DOXYGEN__) /** * @brief Returns the first thread in the system. * @details Returns the most ancient thread in the system, usually this is * the main thread unless it terminated.

# 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
