3x3x3 LED Cube - can i use16f628 instead 16f690

RA4/T0CKI/CMP2 RA4 ST OD Bidirectional I/O port. Output is open drain type.
T0CKI ST — External clock input for TMR0 or comparator output
CMP2 — OD Comparator 2 output

This is from the datasheet. You need to connect the led from 5v to RA4 or add a transistor/buffer like birdman already said
 
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.
kssoin

thank u mr. be80be. to day will chek it
 
Nice, but I've always thought these kinds of LED cubes would look a whole lot better if SMD LED's were used because the package size is so much smaller there's a lot less to get in the way of the eye.
 
3x3x6 led cube


mr. be80be,how can exentend it 3x3x6 led cube. becose 3s pin not used in this project .so i want used it for exetend [6] layer.
 
A 3x3x6 would take 3 more output pins you could added them but you will need a bigger chip like the 16f877 or 16f876
And you'll need drivers for leds
