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. -``` |
