Power-saving modes (idle, power-down, and power-save)Code ExamplesHere are a few code examples to demonstrate how to use the ATmega16 microcontroller in different contexts:### Example 1: Blinking an LED using a GPIO PinIn this example, we'll use the ATmega16 to blink an LED connected to pin PB0.```c
#include <avr/io.h>
#include <util/delay.h>int main(void) {
// Set pin PB0 as output
DDRB |= (1 << PB0);while (1) {
// Set pin PB0 high (turn on the LED)
PORTB |= (1 << PB0);
_delay_ms(500);// Set pin PB0 low (turn off the LED)
PORTB &= ~(1 << PB0);
_delay_ms(500);
}return 0;
}
```### Example 2: Reading Analog Values from a Sensor using ADCIn this example, we'll use the ATmega16's ADC to read analog values from a sensor connected to pin PC0.```c
#include <avr/io.h>
#include <avr/interrupt.h>#define ADC_VREF 2.56 // Vref (volts)int main(void) {
// Initialize ADC
ADMUX = (1 << REFS0) | (1 << REFS1); // Vref = 2.56V
ADCSRA = (1 << ADEN) | (1 << ADPS2) | (1 << ADPS1); // Enable ADC, prescaler = 64while (1) {
// Start ADC conversion
ADCSRA |= (1 << ADSC);// Wait for conversion to complete
while (ADCSRA & (1 << ADSC));// Read ADC value (0-1023)
uint16_t adc_value = ADC;// Calculate voltage (0-2.56V)
float voltage = (adc_value ADC_VREF) / 1024.0;// Print or use the voltage value as needed
// ...
}return 0;
}
