- [ ] support I/O expander (MCP23018)
- [ ] support MCU & I/O expander (MCP23018) mixture like ErgoDox
## Current performance
| MCU | delay type | execution time <br> of <br> `matrix_scan()` | matrix scan rate |
|-------------------|---------------|------------|-----------------|
| Pro Micro (16MHz) | fast adaptive | 75.6us | 8090 scans/sec |
| Proton C (72MHz) | fast adaptive | 49.8us | 15100 scans/sec |
## Configuration
This matrix.c requires a different configuration than quantum/matrix.c.
