How to display letters in embedded c programming? 8051 and keil compiler
For Example
/* Display "E" at 2nd column in first row */
/* Display "T" at 3rd column in first row */
/* Display "0" at 3rd column in second row */
For Example
/* Display "E" at 2nd column in first row */
/* Display "T" at 3rd column in first row */
/* Display "0" at 3rd column in second row */
C:
#include<reg51.h>
/* Data pins connected to port P1 of 8051 */
#define Data_Port_Pins (P1)
sbit Register_Select_Pin = P2^0; /* Register Pin of LCD connected to Pin 0 of Port P2 */
sbit Read_Write_Pin = P2^1; /* Read/Write Pin of LCD connected to Pin 1 of Port P2 */
sbit Enable_Pin = P2^2; /* EN pin connected to pin 2 of port P2 */
/* Function for creating delay in milliseconds */
void Delay(unsigned int wait)
{
unsigned i, j;
for(i = 0; i < wait; i++)
for(j = 0; j < 1200; j++);
}
/* Function to send command instruction to LCD */
void LCD_Command (unsigned char command)
{
Data_Port_Pins = command;
Register_Select_Pin =0;
Read_Write_Pin=0;
Enable_Pin =1;
Delay (2);
Enable_Pin =0;
}
/* Function to send display data to LCD */
void LCD_Data (unsigned char Data)
{
Data_Port_Pins = Data;
Register_Select_Pin=1;
Read_Write_Pin=0;
Enable_Pin =1;
Delay(2);
Enable_Pin =0;
}
/* Function to prepare the LCD and get it ready */
void LCD_Initialization()
{
LCD_Command (0x38);
LCD_Command (0x0e);
LCD_Command (0x01);
LCD_Command (0x81);
}
void main()
{
/* Display "E" at 2nd column in first row */
/* Display "T" at 3rd column in first row */
/* Display "T" at 3rd column in second row */
}
