![]() ![]() Lcd_SetBit(Lower_Nibble) //Send Lower half Lcd_SetBit(Upper_Nibble>4) //Send upper half by shifting by 4 Void Lcd_Print_Char(char data) //Send 8-bits through 4-bit mode Void Lcd_Print_Char(char data) : Once the cursor is set we can write a character to its position by simple calling this function. Void Lcd_Print_String(char *a): If a group of characters is to be displayed, then the string function can be used. ![]() Lcd_Print_Char(a) //Split the string using pointers and call the Char functionĮach time the Lcd_Print_Char(char data) is called, its respective character values is sent to the data-lines of the LCD. These characters reach the HD44780U in form of bits. Now this IC relates the bits to the character to be displayed by using its ROM memory as shown the below table. You can find bits for all the characters in the datasheet of HD44780U LCD Controller. Now, since we are satisfied with our header file let’s build the circuit and test the program. ![]()
