I need to measure pulses from an digital or analog port, then with a simple algotitm calculate frequency. The sensor give to me logic pulses, and i can count this pulses in certain magnitude of time and calculate the frequency every minute.
If the frequency is over certain value i need to write a regiter with the FREQUENCY and a time stamp inside the log (TXT). I need to do this all the time.
Please help me to do this.
Thank you,
Frank
