## Choosing which board to plug the USB cable into (choosing Master)
|
||||||
Example: `make minidox/rev1:default:avrdude`
|
|
||||||
|
|
||||||
Choosing which board to plug the USB cable into (choosing Master)
|
Because the two boards are identical, the firmware has logic to differentiate the left and right board. It uses two strategies to figure things out, [EE_HANDS](https://docs.qmk.fm/#/feature_split_keyboard?id=handedness-by-eeprom) or [by define](https://docs.qmk.fm/#/feature_split_keyboard?id=handedness-by-define). See [setting-handedness](https://docs.qmk.fm/#/config_options?id=setting-handedness) for more information.
|
||||||
--------
|
|
||||||
Because the two boards are identical, the firmware has logic to differentiate the left and right board.
|
|
||||||
|
|
||||||
It uses two strategies to figure things out: look at the EEPROM (memory on the chip) or looks if the current board has the usb cable.
|
|
||||||
|
|
||||||
The EEPROM approach requires additional setup (flashing the eeeprom) but allows you to swap the usb cable to either side.
|
|
||||||
|
|
||||||
The USB cable approach is easier to setup and if you just want the usb cable on the left board, you do not need to do anything extra.
|
|
||||||
|
|
||||||
### Setting the left hand as master
|
|
||||||
If you always plug the usb cable into the left board, nothing extra is needed as this is the default. Comment out `EE_HANDS` and comment out `I2C_MASTER_RIGHT` or `MASTER_RIGHT` if for some reason it was set.
|
|
||||||
|
|
||||||
### Setting the right hand as master
|
|
||||||
If you always plug the usb cable into the right board, add an extra flag to your `config.h`
|
|
||||||
```
|
|
||||||
#define MASTER_RIGHT
|
|
||||||
```
|
|
||||||
|
|
||||||
### Setting EE_hands to use either hands as master
|
|
||||||
If you define `EE_HANDS` in your `config.h`, you will need to set the
|
|
||||||
EEPROM for the left and right halves.
|
|
||||||
|
|
||||||
The EEPROM is used to store whether the
|
|
||||||
half is left handed or right handed. This makes it so that the same firmware
|
|
||||||
file will run on both hands instead of having to flash left and right handed
|
|
||||||
versions of the firmware to each half. To flash the EEPROM file for the left
|
|
||||||
half run:
|
|
||||||
```
|
|
||||||
avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:"./quantum/split_common/eeprom-lefthand.eep"
|
|
||||||
// or the equivalent in dfu-programmer
|
|
||||||
|
|
||||||
```
|
|
||||||
and similarly for right half
|
|
||||||
```
|
|
||||||
avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:"./quantum/split_common/eeprom-righthand.eep"
|
|
||||||
// or the equivalent in dfu-programmer
|
|
||||||
```
|
|
||||||
|
|
||||||
NOTE: replace `$(COM_PORT)` with the port of your device (e.g. `/dev/ttyACM0`)
|
|
||||||
|
|
||||||
After you have flashed the EEPROM, you then need to set `EE_HANDS` in your config.h, rebuild the hex files and reflash.
|
|
||||||
|
|
||||||
Note that you need to program both halves, but you have the option of using
|
|
||||||
different keymaps for each half. You could program the left half with a QWERTY
|
|
||||||
layout and the right half with a Colemak layout using bootmagic's default layout option.
|
|
||||||
Then if you connect the left half to a computer by USB the keyboard will use QWERTY and Colemak when the
|
|
||||||
right half is connected.
