1.5.16.4 PDECx_QDECPositionGet Function

C

uint16_t PDECx_QDECPositionGet ( void ) // x is instance of the peripheral and it is applicable only for devices having multiple instances of the peripheral.

Summary

Reads the angular position from the quadrature encoder.

Description

This function reads the position from the quadrature encoder by reading as tracked by the channel counter.

Precondition

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

Parameters

None.

Returns

Returns Position of the encoder. This consists of the angular position and revolution counter.

Example

int16_t position;

PDEC_QDECInitialize();
PDEC_QDECStart();
position = PDEC_QDECPositionGet();

Remarks

In counter-clockwise direction, position counter works in down counting mode. Returned position must be decoded as angular position and revolution counter based on the ANGULAR bit field value.
