# bluepill splittest
|
||||
|
||||
This is the splittest example for the bluepill MCU.
|
||||
To trigger keypress, short together pins _B10_ and _B1_.
|
||||
|
||||
## Keyboard Configuration
|
||||
|
||||
The type of communication (bitbang, serial (half/full duplex)) is set by the keymap `config.h` file with variables with `SPLIT_` prefix.
|
||||
So this example uses:
|
||||
|
||||
- `config.h` to set which SDI to use for serial. Either define `USE_SDI1_ON_STANDARD_ROLE_PINS`, `USE_SDI1_ON_ALTERNATE_ROLE_PINS` or `USE_SDI2` before the `#ifdef` that configures the default case when none of these variable is defined.
|
||||
- `post_config.h` for defining the communication pins between the halves once the keymap is configured.
|
||||
|
||||
On your keyboard, you most likely will only use `config.h` because you'd have already chosen your communication scheme: serial type, SDI, pins.
|
||||
|
||||
## Wiring
|
||||
|
||||
### Switches
|
||||
|
||||
- Add switches to both Bluepills across B10 and B1 pins
|
||||
|
||||
### Handedness
|
||||
|
||||
Have a look at the [handedness documentation](https://docs.qmk.fm/#/feature_split_keyboard?id=setting-handedness)
|
||||
|
||||
- Add pull-up resistor to left side between VCC and A7
|
||||
- Add pull-down resistors to right side between GND and A7
|
||||
|
||||
### Send power to the other half
|
||||
|
||||
- Connect the following pins on both sides together: GND, VCC
|
||||
|
||||
### Halves data connection
|
||||
|
||||
Choose one of the connection type
|
||||
|
||||
#### serial - bitbang
|
||||
|
||||
- Connect the B8 pins on both sides together
|
||||
|
||||
#### serial - usart half duplex
|
||||
|
||||
Check the [documentation](https://docs.qmk.fm/#/serial_driver?id=usart-half-duplex) to determine the pull-up resistor.
|
||||
|
||||
- To use the default usart (USART1) with the standard role pins,
|
||||
- Connect the A9 pins on both sides together and to add a pull-up resistor on one of these pins
|
||||
- Define USE_SDI1_ON_STANDARD_ROLE_PINS in config.h
|
||||
- To use the default usart (USART1) with the alternate role pins,
|
||||
- Connect the B6 pins on both sides together and to add a pull-up resistor on one of these pins
|
||||
- Define USE_SDI1_ON_ALTERNATE_ROLE_PINS in config.h
|
||||
- To use the usart2 (USART2) pins,
|
||||
- Connect the A2 pins on both sides together and to add a pull-up resistor on one of these pins
|
||||
- Define USE_SDI2 in config.h
|
||||
|
||||
#### serial - usart full duplex
|
||||
|
||||
- To use the default usart (USART1) with the standard role pins,
|
||||
- Connect the mpins on A9, A10 one to the other on each side
|
||||
- Define USE_SDI1_ON_STANDARD_ROLE_PINS in config.h
|
||||
- To use the default usart (USART1) with the alternate role pins,
|
||||
- Connect the pins B6, B7 one to the other on each side
|
||||
- Define USE_SDI1_ON_ALTERNATE_ROLE_PINS in config.h
|
||||
- To use the usart2 (USART2) pins,
|
||||
- Connect the pins A2, A3 one to the other on each side
|
||||
- Define USE_SDI2 in config.h
