Hey guys!!· I have this... this project that I want to accomplish but having some difficulties.· I looked up this IC http://www.utm.edu/staff/leeb/encoder.pdf·which is an IC that theoretically suposed to scan from the keypad and declare a value in the BS2 variable.· I see how to assemble in the above link's pdf doc. but I thrive for the code.· I ran through google in hope to find the code, but ended up with adverse results.· Anyone has an advice where I may obtain the code?· Thanks a lot.confused.gif

    I have posted code several times on this chip since I use it a lot myself.· This is a subroutine that returns an ASCII value for a key pressed fitting the layout listed in the source (4X4 Grayhill).
