I'm a freshman for using iMX6, in my current company,we use iMX6Dual with Vxworks 7 for the development.Now I need to driver a rotatory knob of which 2 input capture pins need to be used.
Through data sheet, I know there are GPT_CAPTURE1 and GPT_CAPTURE2 signals for the feature input capture.
Does anyone can help me on this? For example, how to set the corresponding contents in DTS file, how to configure these GPT_CAPTURE1 and GPT_CAPTURE2 signal to the actual pin?and how to write some example interruption codes? Thanks a lot!
