I have the sine and cosine signal of a speed sensor connected to GPIO-32 and 34 of the F28069M MCU. The signals consist of 16 pulses each (8 rising, 8 falling), and I need to get the speed from these pulses. When I built my custom hardware I didn't consider the fact that the eCAP module would be perfect to use for this, so the signals are now connected to pins that don't have the eCAP functionality.
So, is there a way to manually retrieve the time between two consecutive pulses? If not, the only option would be to modify the hardware so I can attach the signal to GPIO's that do support eCAP.
