How to assign I/O port for 6 hall sensor signal input? Check the TMS320F28051PNT, There is one eCAP module for 3 hall sensor. So, How to define the another 3 hall sensor for hardware port? If use general purpose I/O for the 3 hall sensor, how to fulfill the the capture function? Thanks!

Hi,

There is 1 ECAP module, and eCAP accepts 1 input. How are you planning to connect 3 sensor inputs to the same eCAP? Are you using some external logic?

Hi,

If you need an additional capture unit and if eQEP is available, it can be used as Capture module.
Please see the details in the below document.
