# Cradio keyboards
|
|
|
|
|
|
|
|
Cradio are minimalist 34-key split-keyboards designed with no diodes, using direct micro-controller pin wiring.
|
|
|
|
## Keyboard Info
|
|
|
|
* Keyboard Maintainer: [David Barr](https://github.com/davidphilipbarr)
|
|
* Hardware Supported:
|
|
* [Cradio](https://github.com/davidphilipbarr/36keys/tree/master/34Keys)
|
|
* [Sweep](https://github.com/davidphilipbarr/Sweep)
|
|
* [Hypergolic](https://github.com/davidphilipbarr/hypergolic)
|
|
* Variants of the same 34-key direct pin PCB
|
|
* Hardware Availability: order PCBs using gerber files from the repository
|
|
|
|
Make example for this keyboard (after setting up your build environment):
|
|
|
|
make cradio:default
|
|
|
|
See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).

## Setting Handedness
|
|
|
|
Firmware uses [handedness by EEPROM](https://docs.qmk.fm/#/feature_split_keyboard?id=handedness-by-eeprom) as default and it must be *configured once* on each side. The make commands are:
|
|
|
|
make cradio:default:dfu-split-left
|
|
make cradio:default:dfu-split-right
|
|
|
|
[QMK Toolbox](http://qmk.fm/toolbox) can also be used to set EEPROM handedness. Place the controller in bootloader mode and select menu option Tools -> EEPROM -> Set Left/Right Hand
|
|
|
|
## Bootloader
|
|
|
|
Enter the bootloader in 3 ways:
|
|
|
|
* **Bootmagic reset**: Hold down the top left key on the left half (or the top right right key on the right half) and plug in the controller on that side.
|
|
* **Physical reset button**: Briefly press the reset button soldered on the PCB.
|
|
* **Keycode in layout**: Press the key mapped to `RESET` if it is configured.
|
|
|
|
## Swapped Pins
|
|
|
|
If you have one of the PCB variant with swapped letters `Q` and `B` / `P` and `N`, add the following code to your keymap's `config.h` to swap pins `E6` and `D7` in the firmware:
|
|
```c
|
|
#undef DIRECT_PINS
|
|
#define DIRECT_PINS { \
|
|
{ D7, F7, F6, F5, F4 }, \
|
|
{ B1, B3, B2, B6, D3 }, \
|
|
{ D1, D0, D4, C6, E6 }, \
|
|
{ B4, B5, NO_PIN, NO_PIN, NO_PIN } \
|
|
}
|
|
#undef DIRECT_PINS_RIGHT
|
|
#define DIRECT_PINS_RIGHT { \
|
|
{ F4, F5, F6, F7, D7 }, \
|
|
{ D3, B6, B2, B3, B1 }, \
|
|
{ E6, C6, D4, D0, D1 }, \
|
|
{ B5, B4, NO_PIN, NO_PIN, NO_PIN } \
|
|
}
|
|
```
