-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:
-
-![serial wiring](https://i.imgur.com/C3D1GAQ.png)
-
-The wiring for i2c:
-
-![i2c wiring](https://i.imgur.com/Hbzhc6E.png)
-
-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.
-```
