Hello All on this thread,
I am just staring on this project. after going through this thread i thought of getting the schematic cleared from you. I will use pic16F628A.
Port B will be used for the eight LEDS on each layer(RB0 to RB7).
RA0 for top layer common point.
RA1 for middle layer common point.
RA2 for the bottom Layer common point.
and RA3 for the ninth LED on each layer.
Please let me know if this setup ok.
Will the code need any change?
Regards.
