The following is an animation of a costumed characters that make up the shape of pyramid.

Custom characters array:

   1: const unsigned char p2[8][8] = {{0,0,0,0,0,0,0,0x1F},

   2:                                  {0,0,0,0,0,0,0x1F,0x1F},

   3:                                  {0,0,0,0,0,0x1F,0x1F,0x1F},

   4:                                  {0,0,0,0,0x1F,0x1F,0x1F,0x1F},

   5:                                  {0,0,0,0x1F,0x1F,0x1F,0x1F,0x1F},

   6:                                  {0,0,0x1F,0x1F,0x1F,0x1F,0x1F,0x1F},

   7:                                  {0,0x1F,0x1F,0x1F,0x1F,0x1F,0x1F,0x1F},

   8:                                  {0x1F,0x1F,0x1F,0x1F,0x1F,0x1F,0x1F,0x1F}};

Final Result of Pyramid:

Project Description:

This project will attempt to accomplish the following:

1. Utilize the LCD abilities of creating Custom Characters to build a customized Pyramid.

2. Create a code that will animate the custom characters

3. Move the animation across all 4 lines of the 20×4 LCD module.


1. uC : PIC18F4520 @ Microchip

2. External Clock (Oscillator) : 10MHz

3. Internal Clock (Oscillator) : 40MHz

4. LCD : 20×4 HDM20416L-1-YA0S


1. Editor IDE : MPLAB IDE v8.40

2. Compiler : MPLAB C18 v3.34

3. Internal clock is set to 4xPLL = 4×10MHz = 40MHz
