Here is an example of creating Ω symbol on 5×8 dot matrix. We can simply create a custom character by defining each pixel in the dot matrix. Most of the commonly available displays uses 5×8 dot matrix. We can store up to eight 5×8 character dot patterns or four 5×10 character dot patterns in this memory.Ĭharacters are displayed on the LCD using 5×8 or 5×10 dot matrix. So we can store our custom character patterns in this memory through program. This memory works similar to CGROM but as this is a RAM we can modify its data any time. Its capacity is 80×8 bits, ie 80 characters. This is the memory which holds the character data which is currently displayed on the LCD screen. It can generate 208 5×8 dot character patterns and 32 5×10 dot character patterns. This is the memory which holds 5×8 or 5×10 dot patterns of predefined characters in the LCD.

In this tutorial we will learn, how to create custom characters on LCD using PIC Microcontroller and MPLAB XC8 compiler. HD44780 compatible controllers used in these LCDs allows us to define 8 custom characters in addition to the standard pre-programmed characters. I hope that you already go through our tutorial, Interfacing LCD with PIC Microcontroller – MPLAB XC8. Now to receive from serial pin you can do it 2 ways.
Please read the peripheral library document located at C:\Program Files (x86)\Microchip\xc8\Next will be to make PIC receive what you send in. Now, that is the communication from PIC to outside.
