我制作了一个版本,主要做了以下改进:
1、睡眠、休眠正常(除蓝牙崩溃),牺牲打开盖子唤醒功能(通过电源键唤醒)
2、触控板走SMBus
3、显示正常,外接支持4K30

1、蓝牙睡眠唤醒后有崩溃问题,需要用blueutil 重启蓝牙。
2、按 option command insert 组合键会直接重启
等有空传Github分享出来。

## 특징
1) I2C 회로도 구성
**동기식**
- 마스터에서 클럭보내고 해당 신호에 맞게 슬레이브가 맞춤
7비트 통신주소 -> 128개인데 왜 112개만 가능한건가요? (16개는 이미 예약되어있다거나? 못쓴다거나?)
- 아래에 마스터 최대 갯수 무한대, 슬레이브 최대 갯수 1008개로 되어있는데 얘랑은 또 다른건가요?
