int32_t encoders_microb_get_value

(

void *

number

)

Extract encoder value.

Parameters:

data

: a (void *) that is casted in (uint8_t) containing the number of the encoder to be read.

Extract encoder value.

Parameters:

number

: a (void *) that is casted in (int) containing the number of the encoder to be read.

void encoders_microb_manage

(

void *

dummy

)

Update encoders values, need to be done quite often (Fmax_encoders/64). First, encoders 0 2 4 6 are read, and at next call encoders 1 3 5 7.

Parameters:

dummy

: a (void *) pointer that is not used. It is here according to the encoders interface.
