If the board is [beeping](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Diagnostics)
* Make sure you are using the sensor cable(left=CONTROL_PWM_lEFT or right=CONTROL_PWM_RIGHT) selected in config.h
* You might have a defective input, because of a fried resistor or MCU pin (e.g. [issue](https://github.com/EFeru/hoverboard-firmware-hack-FOC/issues/244)), you can configure the firmware to work on the other cable

PWM is highly prone to noise : keep cables short, use 100nf capacitors, use shielded cable, use ferrites, stabilize voltage.
