Acheron Apollo QMK firmware

The Apollo is Acheron Project's family of open-source, freely available tenkeyless (TKL) keyboard Printed Circuit Boards (PCB) which main feature is the per-key RGB lighting.

• Keyboard Maintainer: Gondolindrim
• Hardware Supported: open-source PCB using the Joker template. First units were manufactured using STM32F401 microcontroller;
• Hardware Availability: these PCBs are open-source so you can manufacture them yourself or order them from a factory. See the project's documentation for more information.

As of april 7, 2022, Apollo comes in three different layouts:

• 87H (default ANSI)
• 87H-T-SC (ANSI with tsangan bottom row and stepped caps);
• 88H-T-SC (ANSI with F13, tsangan bottom row and stepped caps);

See each variant's README for more information on flashing.

Flashing instructions

Step 1: enter bootloader

The DFU state in the bootloader can be accessed in 3 ways:

• Bootmagic reset: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
• Physical reset button: press the physical button on the back of the PCB for at least five seconds
• Keycode in layout: Press the key mapped to QK_BOOT if it is available (ESC key at layer 1 in the default layout)

Step 2: compile firmware

After accessing the DFU state in your PCB, build the default layout using:

make acheron/apollo/87h/gamma:default # For 87H revision Gamma
make acheron/apollo/87h/delta:default # For 87H revision Delta
make acheron/apollo/87htsc:default # For 87H-T-SC (only a single revision as of may 2022)
make acheron/apollo/88htsc:default # For 88H-T-SC (only a single revision as of may 2022)

Step 3: flashing

You can use a flashing tool like dfu-util or QMK Toolbox to download the resulting *.bin file into your PCB.

(Alternative) Compile and flash

After accessing the DFU state in your PCB, you can compile-and-flash automatically using dfu-util through

make acheron/apollo/<variant>:default:flash

VIA firmware

When compiling, just substitute default for via.
