Ok Nigel,
It's what I thought. Clock speed is the trick here.
I was thinking, since this display will be used for numerical and alphabetical character display only, that a slower clock speed should be OK.
Not quite sure, as this is a first for me.
Trying to make digital readout for my mill. I just thought I could update a bit by having tft display instead of small lcd or even 7 segment LED's.
I'll try and see @ 20Mhz with old PIC 16f877. As you notice half of the pins are ground, so 16f877 has plenty of pins for driving.
I'll let you know if it works.
I also kept the power supply and pc board in back of display, and also the driver board . Unfortunately it has no way to interface with PIC.
Thanks for your help.
