Hi Brandon

Making custom characters demands few commands to be executed like this:

Lcd8_Cmd(72);    

 

Lcd8_Write_Char(0);      //ROW 1

Lcd8_Write_Char(14);  //ROW 2 

Lcd8_Write_Char(10);    //ROW 3  

Lcd8_Write_Char(10);    //ROW 4

Lcd8_Write_Char(31);    //ROW 5

Lcd8_Write_Char(27);    //ROW 6

Lcd8_Write_Char(31);    //ROW 7

Lcd8_Write_Char(31);    //ROW 8

 

Lcd8_Cmd(0xcf);

Lcd8_Write_Char(1);

 

The values written inside the row commands above such as 0, 14, 10, etc are the decimal equivalent of 5 bits in a row where writing a logic '1' to any bit represents a black dot over that point while logic '0' clears it away. This particular code will generate a small "lock" like character of 5X8 pixels.

Just give it a try and you'll understand this much better.
