| Hi,
 if monitoring more than 2 pins using the PCA will have it's limitations. You might consider using an 8051 derivative from cypress CY7C68013. This one cannot boast a single cycle core but it has a quite capable xdata DMA modus and an USB 2.0 interface. I don't know from where you start and what your rationals are but eventually this might be interesting: http://volodya-project.sourceforge.net/fx2_progr...rammer.php and I guess (note: I've not been there, not tested it and providing this just as a guess), you eventually can just connect the pins you want to monitor instead of the ADC there: http://volodya-project.sourceforge.net/SR/sr.php (Maybe add a latch or so...) Know what you're doing! Greetings, Frieder |
