hi,
The 'cap waiting timing' indicates that the 628A is running OK.
Check RB6 input pin , you should see a square wave, try it both when in Cap and Ind mode selection.
yes the RB 6 port is giving square wave output in cap and ind mode, I found out that the crystal oscillator I'm using is not 3.276Mhz but its 3.579Mhz as the former is not available here.Can this be a possible reason?View attachment 63778View attachment 63778
another information that the compiler is giving is "controller received command while busy > source LCD' maybe the lcd is sending acknowledgement in wrong time?
