Tips and Tricks (14)
Smash the miror!
Balau wrote an interesting post on “Programming Arduino Uno in pure C”. This is a pretty good starting point for those who would like to get one step further from Arduino to the whole AVR world!
Here is a look and feel about blink sketch in “pure C”
#include <avr/io.h>
#include <util/delay.h>
enum {
BLINK_DELAY_MS = 1000,
};
int main (void)
{
/* set pin 5 of PORTB for output*/
DDRB |= _BV(DDB5);
while(1) {
/* set pin 5 high to turn led on */
PORTB |= _BV(PORTB5);
_delay_ms(BLINK_DELAY_MS);
/* set pin 5 low to turn led off */
PORTB &= ~_BV(PORTB5);
_delay_ms(BLINK_DELAY_MS);
}
return 0;
}
