This variant can be used with potentiometers or hall sensors.
This variant can be used with analog inputs like potentiometers, joysticks or throttle/brake handles, even if using hall sensors.
## Configuration/Parameters
* ADC_ALTERNATE_CONNECT : to swap the inputs, in case you cannot do it physically
* ADC_PROTECT_THRESH : to adjust the threshold below/above the MIN/MAX ADC values that will trigger ADC protection
* ADC_PROTECT_TIMEOUT : number of wrong / missing input commands before safety state is taken
## Wiring:
* Connect blue wire (ADC1) to steering and green wire (ADC2) to speed on left sensor board cable
* If you dont need steering, set input1_type to 0 in order to disable the input or go through the auto-calibration procedure
* 100k Pull down resistors connected to ground are recommended to prevent issues when inputs are floating (wire is cut or disconnected)
* 100k Pull down resistors connected to ground are recommended to prevent issues when inputs are floating (wire is cut or disconnected) triggering ADC protection
⚠ Red wire from sensor cable delivers 15v !!!
Use 3.3v from programming port or a voltage regulator.
## Calibration:
Proceed with [calibration](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Input-Calibration) for better control.

## Troubleshooting:
If wheels are not spinning or the board is [beeping](https://github.com/EmanuelFeru/hoverboard-firmware-hack-FOC/wiki/Diagnostics)), make sure you have done proper calibration.
