#5853 - RE: How to read a 4x4 keyboard |
A good book on the subject is "The 8051 Microcontroller Architecture, Programming, and Aopplications by Kenneth J. Ayala"
ISBN 0-314-77278-2. Page 132 thru page 151 gives explanation of different keyboards one of which is a 4*4 matric key pad with code in asmembly is described. I have done many projects copied with slight modification for a 4x4 matric's keyboard and they all have worked fine. Good Luck Charles Bannister HawaiianComputer@aol.com |
