Re: Data acquisition thru serial port

I don't think the Pocket PC has the ability to count these pulses? the CPU
freqency is 204mhz for a ARM processor
that would have to be one hell of a tight loop of counting code.. a rise and
a fall would both be a signal that would have to be counted. that is 200
changes a sec...
