5 LED CUBE Controller for PIC16F688

Circuit Description The LED cube is made up from 125 LEDs arranged into 5 layers of 25 LEDs each.  The display itself is multiplexed so instead of requiring 125 connections it requires one to each of the five layers and 25 to each LED in a layer making a total of 30.  The cube is refreshed by a software interrupt routine with each layer active for 2ms, so the entire cube is refreshed every 10mS (100Hz).

3x3x3 LED Cube using PIC16F690 microcontroller

3x3x3 LED Cube Here is my 3x3x3 LED Cube project. It runs using a PIC16F690. Along with the brief explanation of how to make it, I have also included the .asm file for the PIC and a piece of software written in VB.NET that you can create your own LED patterns. These can be exported as .asm files and put into the main .asm code. Building Each layer of 9 LEDS are connected with all of the cathodes together. T ...
