## Current Limit
You can adjust I_MOT_MAX/I_DC_MAX parameters in config.h file to decrease/increase current limit(Amps). I_DC_MAX should be equal to I_MOT_MAX + 2A.
## Speed Limit
You can adjust N_MOT_MAX in config.h file to decrease/increase the speed limit(RPMs).<br>
Be aware that the firmware has a hard limit of 2000 RPMs to prevent overflows.<br>
The speed can overshoot the limit, this is a know [issue](https://github.com/EFeru/hoverboard-firmware-hack-FOC/issues/132).<br>
## Setting up the Current and Speed limits on the go
This feature let's you change the Max Current(I_MOT_MAX) and Max Speed(N_MOT_MAX) on the go without having to modify [config.h](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/blob/master/Inc/config.h) and flash the board
* press the power button for more than 5 sec and immediately after the beep sound press one more time shortly
* move and hold the pots to a desired limit position for Max Current(INPUT1) and Max Speed(INPUT2), maximum being the values you have put in config.h
* press the power button to confirm or wait for the 10 sec timeout
⚠The settings will be stored in flash memory and will be erased only 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. It will be only erased from flash memory if you fully delete memory before flashing.<br>
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).
