    Windmilling CallBack Handler never Called

    Hi,
    I am trying to read wind-milling speed using GTP12 CR Interrupt. I have set the parameters according to the documentation, still my interruption handler is never called. A sample project is attached to this post.
    First, Iíve copied the Block Commutation sample project. Then, using the configuration wizard and set the following parameters:
    - In the BEMF tab:
    - The connect to GPT2.CAPIN: True
    - Capture input select: Phase U
    - Blank filter enable: False
    - In the GPT12E tab:
    - Capture into CAPREL enabled: True
    - CAPREL Capture rigger Selection: rising edge on CAPIN
    - CAPREL -> CAPTURE Interrupt: True
    - Enable Interrupt: True
    - Call Back: Caprel_Handler

    Yet the Caprel_Handler function is never called even after I force the motor into the windmilling state using another motor.

    Can anyone help me, please?

    Thanks,
    Wagner.

    Hi wskeller,
    thanks for your post. Could you please attach a screenshot of your config wizzard settings? We will try to reproduce the behavior then.

    Best regards
