LCD contrast

Adjusts LCD contrast

Code Example

// Put Signature to EEPROM


uint8_t ee_pwm __attribute__((section(".eeprom"))) = 0xA5;

// *****************************************************************

int main (void)
{
	unsigned char pwm =0;

	// Initialize the system 

	uart0Init(19200);		// Initialize uart1

	
	// Send messages to terminal window

	uart0Printf("\n\rBIPOM MINI-MAX/AVR");
	
	// LCD

	lcdInit();	// Initialize LCD module 

	pwmInit();	// Adjust LCD contrast 


	lcdControlCursor(CURSOR_OFF); // Disable LCD cursor 

	lcdClearDisplay(); // Clear Display 

	
	// Print test message to TOP line 

	lcdSetTopLine();	
	lcdPrintf("BIPOM MINI-MAX/AVR");

  	for(;;)
	{
		for(pwm = 180;pwm<=250;)
		{
			PWM = pwm;		 // adjust LCD contrast 

			lcdSetTopLine(); // Set Top Line 

			lcdPrintf("Contrast : %02d",pwm);
			_delay_ms(3000);
			pwm += 10;
		}
	}
