Hi Dave,

I did see this article, however, as Henrik mentioned, the circuit described does not interpret quadrature encoding (grey code) to gain accurate angle measurement. I also looked at another solution using an LS7183 which does interpret the output to two separate clock signals (see datasheet here: http://www.lsicsi.com/pdfs/Data_Shee...083_LS7084.pdf), this looks promising if I can't successfully make my code work properly.

I truly appreciate your suggestion.

Chris
