Function Documentation

void encoder_init

(

void

)

Encoder init routine.

Definition at line 77 of file encoder.c.

int16_t encoder_read

(

)

Returns actual value in the counter.

Definition at line 47 of file encoder.c.

void encoder_reset

(

)

Resets encoder counter to 0. Mandatory to run this after calibration, so it counts from 0.
