based boards. based boards.
## First Time Setup
Download or clone the whole firmware and navigate to the keyboards/lets_split directory. Once your dev env is setup, you'll be able to generate the default .hex using:
```
$ make rev2
```
You will see a lot of output and if everything worked correctly you will see the built hex files:
```
lets_split_rev2_serial.hex
lets_split_rev2_i2c.hex
```
If you would like to use one of the alternative keymaps, or create your own, copy one of the existing [keymaps](keymaps/) and run make like so:
```
$ make rev2-YOUR_KEYMAP_NAME
```
If everything worked correctly you will see a file:
```
lets_split_rev2_YOUR_KEYMAP_NAME.hex
```
For more information on customizing keymaps, take a look at the primary documentation for [Customizing Your Keymap](/readme.md##customizing-your-keymap) in the main readme.md.
### Let's split 1.0
If you have a first generation Let's Split you will need to use the revision 1 code. To do so, use `rev1` in all your commands instead.

Flashing Flashing
-------
From the keymap directory run `make SUBPROJECT-KEYMAP-avrdude` for automatic serial port resolution and flashing.
Example: `make rev2-serial-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.
From the keymap directory run `make SUBPROJECT-KEYMAP-avrdude` for automatic serial port resolution and flashing. 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.
Example: `make rev2-serial-avrdude` 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 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 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 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 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 versions of the firmware to each half. To flash the EEPROM file for the left
half run: half run:
``` ```
make eeprom-left avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-lefthand.eep
// or the equivalent in dfu-programmer
``` ```
and similarly for right half and similarly for right half
``` ```
make eeprom-right avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-righhand.eep
// or the equivalent in dfu-programmer
``` ```
After you have flashed the EEPROM for the first time, you then need to program NOTE: replace `$(COM_PORT)` with the port of your device (e.g. `/dev/ttyACM0`)
the flash memory:
``` After you have flashed the EEPROM, you then need to set `EE_HANDS` in your config.h, rebuild the hex files and reflash.
make program
```
Note that you need to program both halves, but you have the option of using 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 different keymaps for each half. You could program the left half with a QWERTY
