I mostly think that nothing is getting transmitted (op-codes, data) I did notice in the copy of my program I posted that I had deleted the % sign in front of the constant value. An accident it was always there. I have never got any read value except for 0, also the program hangs at my device_buisy loop while it is waiting for the write process to end. This is mostly why I do not think anything is happening now. The EEPROM is configured in 16 bit mode I would have to cut a trace and solder in a jumper to change it to 8 bit so I was trying to avoid that and try to get it to work the way it is. I have attached the latest version of the program and the data sheet for the M93C46 EEPROM I am mostly interested in comments and advice mike ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=208841#m209050 Need assistance?
