I am trying to develop a retroft for some instrumentation having bad displays with
an HD6130 controller on one board (with memory) driving a display/w drivers
via serial interface.
I removed the HD6130b and wired the CFAG240128DFMIT to the
vacated pads on the pcb. The schematic shows direct connection to the
6800 controller.
I wired the power inputs to the appropriate voltages that were present.
When I power up I get only the top row of pixels, apparently with a few data points.
Contrast works fine, I think power is all ok.
Am I correct in assuming that the lC7981 is a drop in replacement for the HD6130b
and that the timing and instruction set are compatible?
Any ideas on what signal could be corrupt causing only one line to display?
If I can make this display work it will save tens of thousands of $ on new instruments.
Thanks all.
