1.10.17.1 QEIx_VelocityGet Function

C

/* x = QEI instance number */

uint32_t QEIx_VelocityGet ( void )

Reads the velocity counter from the quadrature encoder.

This function reads the velocity counter. The contents of the counter represent the distance traveled during the time between samples.

QEIx_Initialize function must have been called first for the given channel.

None.

uint32_t - number of samples since the last read

uint32_t velocity;

QEI1_Initialize();
QEI1_Start();
velocity = QEI1_VelocityGet();

The velocity counter is automatically cleared after every processor read of the velocity counter.
