CCS/TMS320F28379D: QEP module

Amrutha Haridas

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

Is there a method of estimating speed/position through rising edge control (XCR=1) with QEPB pulse alone? other than rewiring B to A?

    Hi Amrutha,

    The eQEP module expects the input signal at QEPA while QEPB is mainly used to sense the direction. So if you are just interested in measuring the speed/frequency and not the direction then use UP-Count mode while connecting signal to QEPA.

    It is not very clear why do you not want to use QEPA so could you please elaborate the usecase.
