I would use the one HCTL2000 quadrature decoder/counter interface.I need to count the pulses, determinate if it is going CW or CCW
See details on datasheet @ http://www.datasheetcatalog.org/data.../HCTL-2000.pdf

All progress began with an idea

What type of frequency are we talking about here? If it's rather low frequency, like a knob used to navigate a user interface etc then perhaps using the 'Change-on-PortB' interrupt and decode and keep count in software. If we're talking higher frequencies, like for motorcontrol etc then you might want to look at the 18F24x1 series PICs as they have a QEI-module on board. In any case - use the USART for comms.

If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.

Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves

Thank you
maximum frequency will be around 1000 Pulses/sec
