Similarly, all the rows have to be defined by you. The value on the first row is defined -00001110 means 0E in hexadecimal. ‘x’ means don’t care since it doesn’t matter whatever the value it has after 5 bit because it would not appear on the row. For example- The number for the first line is decided by- xxx01110. The numbers for each row comes from the fact that ‘0’ means off and ‘1’ means on. For example, I had created a character that looks exactly like me. Each row holds a certain value depends according to the character. So far, you may have noticed that each block of LCD is actually made up of 5 columns and 8 rows. We can store maximum 8 custom characters. In the CGRAM, there are some locations available for storing the custom characters. Similarly, each ASCII characters also has an address stored in CGRAM(Character Graphics Random Access Memory).

But here we are going to learn how I had created the character and the block for the game so that you can create your own custom characters.Įach block has an address stored in DDRAM. Right now, I don’t recommend you to create the game (If you don’t know about interrupt)because I had used the interrupt method for jumping the man. I have to press a button to make it jump over it. The objective of the game to prevent him from hitting the block coming on his way by jumping over the block. In the game, I had created a character- a human. I once created a game similar to Google-offline game. Custom Character Generation in 16×2 LCDīefore printing the custom characters on LCD, let’s know what we are going to create. Similarly, If we print an ASCII character as a number (%d) the result displayed is the ASCII value of the character. So if we print a “char” type number as a character(%c), we are actually printing an ASCII character having the same ASCII value(ASCII of A=65). It’s because of the ASCII(American Standard Code for Information Interchange) value of the ‘A’ is 65. If we execute this program, the output would be ’65’ on top row but in the bottom row, ‘A’ should be there. LCDGoto(6,1) // 5th on column second row. For example, what should be the output of particular code? int main(void)

Before starting to learn about the generation of custom characters, we are going to know a bit more about LCD printing program.
