Let's Split
|
||||
======
|
||||
|
||||
This readme and most of the code are from https://github.com/ahtn/tmk_keyboard/
|
||||
|
||||
Split keyboard firmware for Arduino Pro Micro or other ATmega32u4
|
||||
based boards.
|
||||
|
||||
**Hardware files for the Let's Split are now stored at http://qmk.fm/lets_split/**
|
||||
**Hardware files for the sockets version can be found at https://github.com/dumle29/let-s-Split-v2/tree/socket-reverseable**
|
||||
|
||||
## Build Guide
|
||||
|
||||
A build guide for putting together the Let's Split v2 can be found here: [An Overly Verbose Guide to Building a Let's Split Keyboard](https://github.com/nicinabox/lets-split-guide)
|
||||
|
||||
There is additional information there about flashing and adding RGB underglow.
|
||||
|
||||
A build guide for putting together the sockets version can be found here: *Guide will be made and linked here when the PCBs have been received and tested*
|
||||
|
||||
## First Time Setup
|
||||
|
||||
Download or clone the `qmk_firmware` repo and navigate to its top level directory. Once your build environment is setup, you'll be able to generate the default .hex using:
|
||||
|
||||
```
|
||||
$ make lets_split/rev2:default
|
||||
```
|
||||
|
||||
You will see a lot of output and if everything worked correctly you will see the built hex file:
|
||||
|
||||
```
|
||||
lets_split_rev2_default.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 lets_split/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](/docs/faq_keymap.md) 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.
|
||||
|
||||
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.
|
||||
* You only need 3 wires to connect the two halves. Two for VCC and GND and one
|
||||
for serial communication.
|
||||
* Optional support for I2C connection between the two halves if for some
|
||||
reason you require a faster connection between the two halves. Note this
|
||||
requires an extra wire between halves and pull-up resistors on the data lines.
|
||||
|
||||
Required Hardware
|
||||
-----------------
|
||||
|
||||
Apart from diodes and key switches for the keyboard matrix in each half, you
|
||||
will need:
|
||||
|
||||
* 2 Arduino Pro Micros. You can find these on AliExpress for ≈3.50USD each.
|
||||
* 2 TRRS sockets and 1 TRRS cable, or 2 TRS sockets and 1 TRS cable
|
||||
|
||||
Alternatively, you can use any sort of cable and socket that has at least 3
|
||||
wires. If you want to use I2C to communicate between halves, you will need a
|
||||
cable with at least 4 wires and 2x 4.7kΩ pull-up resistors
|
||||
|
||||
Optional Hardware
|
||||
-----------------
|
||||
|
||||
A speaker can be hooked-up to either side to the `5` (`C6`) pin and `GND`, and turned on via `AUDIO_ENABLE`.
|
||||
|
||||
Wiring
|
||||
------
|
||||
|
||||
The 3 wires of the TRS/TRRS cable need to connect GND, VCC, and digital pin 3 (i.e.
|
||||
PD0 on the ATmega32u4) between the two Pro Micros.
|
||||
|
||||
Next, wire your key matrix to any of the remaining 17 IO pins of the pro micro
|
||||
and modify the `matrix.c` accordingly.
|
||||
|
||||
The wiring for serial:
|
||||
|
||||
|
||||
|
||||
The wiring for i2c:
|
||||
|
||||
|
||||
|
||||
The pull-up resistors may be placed on either half. It is also possible
|
||||
to use 4 resistors and have the pull-ups in both halves, but this is
|
||||
unnecessary in simple use cases.
|
||||
|
||||
You can change your configuration between serial and i2c by modifying your `config.h` file.
|
||||
|
||||
Notes on Software Configuration
|
||||
-------------------------------
|
||||
|
||||
Configuring the firmware is similar to any other QMK project. One thing
|
||||
to note is that `MATRIX_ROWS` in `config.h` is the total number of rows between
|
||||
the two halves, i.e. if your split keyboard has 4 rows in each half, then use
|
||||
`MATRIX_ROWS=8`.
|
||||
|
||||
Also, the current implementation assumes a maximum of 8 columns, but it would
|
||||
not be very difficult to adapt it to support more if required.
|
||||
|
||||
Flashing
|
||||
-------
|
||||
From the top level `qmk_firmware` directory run `make KEYBOARD:KEYMAP:avrdude` for automatic serial port resolution and flashing.
|
||||
Example: `make lets_split/rev2: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: looking at the EEPROM (memory on the chip) or looking if the current board has the usb cable.
|
||||
|
||||
The EEPROM approach requires additional setup (flashing the eeprom) 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.
|
||||
```
