⚠ Current and speed limits will be stored in flash memory if you set them up on the go or if you do the auto-calibration, so changing it in config.h file won't have any effect anymore. It will be only erased from flash memory if you fully delete memory before flashing.<br> ⚠ Current and speed limits will be stored in flash memory if you set them up on the go or if you do the auto-calibration, so changing it in config.h file won't have any effect anymore.

An alternative to bypass those settings is to change **FLASH_WRITE_KEY** in [config.h](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/blob/master/Inc/config.h).

## Debug Protocol
Another way to change those settings without flashing the board is the [debug protocol](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Debug-Serial#debug-protocol). You will be able to change the settings via commands through the serial port.
