Thanks.
Definitely making good progress- but The amount of resistors I'm having to add is worrying me a bit.
I have been designing the PCB whilst experimenting and the biggest problem is space for the tracks to be routed. The exrta 32 pulldown resistors arent gonna help me much in that respect. The external power supply in a bit of an inconvenience as well- but I will get it up and running.
The problem with the PCB is that it is only 12x4cm. I have designed with SOIC pic chips to save some room but its still very tight.
If the PIC chip had a better pinout (RA0-7 on one side, RB0-7 on the other), it would fit in perfectly with the layout.
Even with a 4 layer board- I might have to remove the display and place it on top using headers to stand it off-hopefully not though.
I'm not moaning- just thinking ahead
I'm over the moon that its working, though cant wait to tweak it to perfection.
