AVR-Lib

C++ header only libraries optimized for avr

Display.h

this header file is a alpha numeric Lcd Driver Based on Hitachi HD44780 LCD controller

usage sample :

#include "AVR_Lib/Display.h"
#include <util/delay.h>
............................
............................
............................
	Display::LCD_Init();
  Display::LCD_setCursor(0,0);//goto 0,0
  Display::LCD_Disp("AVR_Lib");
  Display::LCD_setCursor(0,1);//goto next line
  Display::LCD_Disp("Test");
  
  _delay_ms(5000);
  Display::ResetDisplay();

Keypad.h

this header file is a 4*4 keypad Driver with both normal and pullup input capture implemented

usage sample :

#include "AVR_Lib/Keypad.h"
............................
............................
............................
while (true)
  {
  	
  	inputs inp=Keypad::CapturePullupInput();
  	
  	//if some input captured prevent Debunce
  	if (inp!=inputs::End)
  	{
  		_delay_ms(350);
  	}
  	
  	switch(inp){
  		
  		case inputs::zero:
  		
  		break;
  		case inputs::one:
  		
  		break;
  		case inputs::two:
  		
  		break;
  		case inputs::three:
  		
  		break;
  		case inputs::four:
  		
  		break;
  		case inputs::five:
  		
  		break;
  		case inputs::six:
  		
  		break;
  		case inputs::seven:
    
  		break;
  		case inputs::eight:
    
  		break;

  		break;
  		case inputs::plus:
  		
  		break;
  		case inputs::minus:
  		
  		break;
  		case inputs::devision:
  		
  		break;
  		case inputs::multiply:
  		
  		break;
  		case inputs::Evaluate:
   			 // = is pressed
  		break;
  		
  		case inputs::End:
  		//no input do noting
  		break;
