Hi,
I'm facing a issue with the F28335 about high frequence input pulse counting.
In my application, I want to use F28335 (100MHz) capture 4 channel input pulses (freq from 200Hz to 125kHz),
and i want to get the total number of each channel input pluse.
As i know, it's possible to do the pulse counting though the GPIO interrupt by connect those 4 pulse signal to the GPIO XINTx.
But in this application, i do not want F28335 interrput so frequently (maybe 125K) to knock-down the CPU's efficiency.
I have try to use eQEP do this job, but these are only 2 eQEP unit found in F28335.
Can anybody give me some idea. i am really confused.. waiting for your reply. thanks!
