Since some are on the subject of encoders, I have a problem I would like to
get help on. I have a hall effect sensor dutifully counting pulses on a
gear. The gear will rotate from 800-4000 RPM. I am running the signal
through a 741 OP Amp to condition and amplify. I get a beautiful square wave
output to my analog input on the handy board. The test signal is a 35.3 ms
rep rate or 1730 RPM, but the handy board does not keep a good count. I am
using fencdr5.icb. Hi and low thresholds are at 220 and 110 respectively.
This problem is driving me nuts. Any help?

| IC can't sample the A/D converters that quickly. As long as you're generating a nice squarewave you could connect it to one of the input capture pins and write a custom interrupt routine to maintain the count. --Chuck (...) (24 years ago, 10-Sep-00, to lugnet.robotics.handyboard)
