# QSPLIT
## Rev1
I want a split keyboard like quefrency but with encoder and oled just like satisfaction75
## Rev2
Left using teensy++ 2.0 right using pro micro. I want a lot of feature but the pro micro firmware max size is limitting me from adding aditional feature. So I think of mixing different board. And it works. I almost never using the macro key on the left side and I want a dedicated encoder instead of changing layer encoder. And changing layout to make it easier for me to search for keycaps set. build log and the firmware coming soon.

This is my first time building custom handwired keyboard, even though someone else guide me to build this keeb. some mistakes were made, buying wrong part, buying unnecesery part to reach the minimum free shipping terms. buying to many part because the seller only sell in pack and so on. the cost not include the shipping cost, some part get free shipping some part don't. the cost not including the tool to build this keeb, like solder, soldering iron, caliper, multimeter and etc.
## Features
### Rotary encoder
the encoder have layers, you can change it to media layer, scrolling layer, backlit layer and brightness layer. To change encoder layer,simply press `fn1+encoder`. to change base layer like qwerty and so on use `fn2+encoder`.
#### Media layer
in media layer when you press the encoder it is a toogle button play pause `KC_MPLY`. when you turn the encoder clockwise and cc, it is acting as volume up and down (`KC_VOLU`,`KC_VOLD`). but when you turn the encoder while holding fn1 or fn2 it is acting as next and previous/fast forward and rewind button. my idea is awesome right? haha. explaining it in my non native lang is hard, just see my code.
```c
void handle_encoder_switch(void){
if(ENCODER_MODE == media){
tap_code(KC_MPLY);
}
...
}
void handle_encoder_media(bool clockwise, bool fn1, bool fn2){
if(clockwise){
if(fn1){
tap_code(KC_MNXT);
}else if(fn2){
tap_code(KC_MFFD);
}else{
tap_code(KC_VOLU);
}
}else {
if(fn1){
tap_code(KC_MPRV);
}else if(fn2){
tap_code(KC_MRWD);
}else{
tap_code(KC_VOLD);
}
}
}
```
#### Backlit layer
the idea is the same as media layer, when in this layer, the encoder button will act as ... just see my code
```c
void handle_encoder_switch(void){
...
else if(ENCODER_MODE == backlit) {
rgblight_step();
}
...
}
void handle_encoder_backlit(bool clockwise, bool fn1, bool fn2){
if(clockwise){
if(fn1){
rgblight_increase_hue();
}else if(fn2){
rgblight_increase_sat();
}else{
rgblight_increase_val();
}
}else {
if(fn1){
rgblight_decrease_hue();
}else if(fn2){
rgblight_decrease_sat();
}else{
rgblight_decrease_val();
}
}
}
```
#### Brightness layer
it is just brighness nothing else
### Scroll layer
```c
void handle_encoder_scroll(bool clockwise, bool fn1, bool fn2){
if(clockwise){
if(fn1){
tap_code(KC_WH_R);
}else if(fn2){
tap_code(KC_WH_R);
}else{
tap_code(KC_WH_D);
}
}else {
if(fn1){
tap_code(KC_WH_L);
}else if(fn2){
tap_code(KC_WH_L);
}else{
tap_code(KC_WH_U);
}
}
}
```
### 128x32 Oled display
I want the same firmware as satisfaction75 the oled display is awesome, but I can't. So I use font image
edit font using https://helixfonteditor.netlify.app/
### 22 WS2812 RGB lightning (11 each halves)
nothing awesome about this
### Base layer
The base layer is just switching between qwerty mac and qwerty windows by pressing `fn2+encoder`, I can add another like dvorak colemak and etc but I don't want to learn them.

## Finished Build

## Wiring
communication protocol is serial using D3 pin, the LED Din pin use B5 pin, the right halve encoder connected to the i2c pin D1 and D0 so I have to disable the oled driver on the right halve to use encoder, and I can't use the Oled display if the right side is the master, always use left as master.
there is only 1 pin left, B5. I intend to use it for buzzer but the maximum size of pro micro firmware not allow me to add this feature :'(.
## Build Log
This is my first custom keyboard and it is a handwired. I am too excited to finish this keeb ASAP so I don't document my build. but here are some pictures of my build without timestamp.
### Acrylic case arrive
trying the switch on the double layer plate acrylic (1.5mm+3mm). It is fit and click without adding some glue. the doubleplate acrylic idea by @dayatz
### Starting build
at first it looks good
adding the pro micro, trrs, led and etc. Disgusting wiring.
this is suppose to be underglow
I trust my ability so no need to test it on breadboard.
## The end
I am learning so much by building this keyboard, at first it confusing, but once you understand how it works, you can build it faster.
I am not satisfied yet with this keyboard, I will upgrade the mcu and other part. just wait for rev2. forgive my typo and bad grammar,I try my best.
