TMS320F28377D: Route multiple GPIO input signal to a single ecap module

Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

Hi expert,

My customer implement fan speed monitor with ecap module. They would like to use one ecap to do "round-robin" sample of four fans with the help of XBAR. Is that possible to configure XBAR in run time to  "switch" ecap input between different GPIOs?

Could you give me some suggestions in implementing this?

Thanks

Sheldon

    Hi Sheldon,

    Yes, that is possible. Please also refer to "Configuring Device Pins for the eCAP" in Technical Reference Manual for more details.

    Also, inside C2000Ware under eCAP examples you will find capture example that customer can reference to know how to configure eCAP.
