Hello all. I'am currently using a 16c66 running at 14Mhz for some RS-232 data transmission. I've come across a strange problem, the FSR wont retain the data I'am receiving and correctly indexing in it. I'am using interrupts and (I think) all the correct stuff associated with it. What's even more odd it worked at 10Mhz but now, with and 14.318 MHz OSC wont do the ISR correctly.!!! Simulation runs smoothly and accurately but... Any help would be greatly apreciated Thanks a lot in advance -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
