I was wondering if anyone had solved the following idea and could send me some schematics, or point me in the right direction, to save me the trouble of designing the whole lot.... I need to count the pulses coming from a pair of quadrature incremental encoders. These pulses could be conditioned to be up/down. I need to send the counts out to a PC RS232 line. The counts need to be independantly resettable. I am looking at doing it with a PIC16C84. Many thanks Phil
