- [read_keys.py](read_keys.py) Initialize the keyboard MCU and poll key code
|
||||
- [read_keys_SH3.py](read_keys_SH3.py) Scan key matrix and return key name
|
||||
- [read_keys_SH3.py](read_keys_SH3.py) Scan key matrix and return key name(deprecated)
|
||||
- [read_keys_SH3.c](read_keys_SH3.c) Scan key matrix and return key name rewritten with C. nice performance
