Variant ADC

This variant can be used with analog inputs like potentiometers, joysticks or throttle/brake handles, even if using hall sensors. Here is a video walking you through how to setup the firmare to use it with a joystick.

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 don’t 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) triggering ADC protection

⚠ Red wire from sensor cable delivers 15v !!! Use 3.3v from programming port or a voltage regulator.

Calibration:

Proceed with calibration for better control and proper ADC protection.

Troubleshooting:

If wheels are not spinning or the board is beeping, make sure you have done proper calibration.
