Detailed Description

Pedal library.

Enumeration Type Documentation

Stores the possible pedal states that the pedal could be in.

This struct also has a NUM_PEDAL_STATES enum which stores how many possible pedal states there are

StatusCode pedal_calib_sample	(	PedalCalibrationStorage *	calib_storage,
		PedalCalibrationData *	data,
		PedalState	state,
		GpioAddress *	address
	)

Reads data from ADC and calculates appropriate pedal calibration values.

Parameters

calib_storage	- A struct for storing the max and min reading while looping through adc reading for a given number of samples
data	- A struct that stores the final calculated values for the upper and lower values for the pedal
state	- An enum that describes the current state that he pedal is in when calling the function
address	- The GPIO address for the adc of the pedal
