DeltaSplit75
|
||||
======
|
||||
|
||||
This readme and most of the code are from https://github.com/ahtn/tmk_keyboard/ and https://github.com/qmk/qmk_firmware/tree/master/keyboards/lets_split
|
||||
Credit to ahtn and wootpatoot for work on the split keyboard firmware
|
||||
|
||||
Split keyboard firmware for Arduino Pro Micro or other ATmega32u4
|
||||
based boards.
|
||||
|
||||
|
||||
## First Time Setup
|
||||
|
||||
Download or clone the whole firmware and navigate to the keyboards/DeltaSplit75 directory. Once your dev env is setup, you'll be able to generate the default .hex using:
|
||||
|
||||
```
|
||||
$ make V2
|
||||
or
|
||||
$ make ProtoSplit (if you have one of the prototype PCBs)
|
||||
```
|
||||
|
||||
You will see a lot of output and if everything worked correctly you will see the built hex files:
|
||||
|
||||
```
|
||||
DeltaSplit75_ProtoSplit_Default
|
||||
or
|
||||
DeltaSplit75_V2_Default.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.
|
||||
|
||||
### DeltaSplit75 V2
|
||||
The PCBs available in groupbuy are all v2, if you've bought one of my prototype PCBs (it says DeltaSplit65 on the silkscreen instead of 75), use the code $make ProtoSplit instead
|
||||
|
||||
Features
|
||||
--------
|
||||
|
||||
For the full Quantum Mechanical Keyboard feature list, see [the parent readme.md](/readme.md).
|
||||
|
||||
Some features supported by the firmware:
|
||||
|
||||
* Either half can connect to the computer via USB, or both halves can be used
|
||||
independently.
|
||||
* 75% formfactor
|
||||
* Support for multiple Bottom Rows
|
||||
* RGB underglow support
|
||||
* Split Backspace and ISO support
|
||||
|
||||
|
||||
Flashing
|
||||
-------
|
||||
I personally use xLoader to upload my hex files to the keyboard, though any other working software is fine too
|
||||
|
||||
|
||||
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: 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:eeprom-lefthand.eep
|
||||
// or the equivalent in dfu-programmer
|
||||
|
||||
```
|
||||
and similarly for right half
|
||||
```
|
||||
avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-righhand.eep
|
||||
// or the equivalent in dfu-programmer
|
||||
```
|
||||
|
||||
NOTE: replace `$(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.
|
||||
|
||||
|
||||
Notes on Using Pro Micro 3.3V
|
||||
-----------------------------
|
||||
|
||||
Do update the `F_CPU` parameter in `rules.mk` to `8000000` which reflects
|
||||
the frequency on the 3.3V board.
|
||||
|
||||
Also, if the slave board is producing weird characters in certain columns,
|
||||
update the following line in `matrix.c` to the following:
|
||||
|
||||
```
|
||||
// _delay_us(30); // without this wait read unstable value.
|
||||
_delay_us(300); // without this wait read unstable value.
|
||||
```
