# 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](https://github.com/Gondolindrim)
|
|
* Hardware Supported: open-source PCB using the [Joker template](https://acheronproject.com/joker_mcus/joker/). 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](https://acheronproject.com/pcbs/apollo/apollo/) 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 `RESET` 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`.
