Tengo el siguiente código para probar un LED:
configGlobal.h
#define F_CPU 1000000UL
#define setBit(sfr, bit) (_SFR_BYTE(sfr) |= (1 << bit))
#define clearBit(sfr, bit) (_SFR_BYTE(sfr) &= ~(1 << bit))
#define toggleBit(sfr, bit) (_SFR_BYTE(sfr) ^= (1 << bit))
main.c
#include "configGlobal.h"
#include <avr/io.h>
#include <util/delay.h>
#define LED PB0
#define LED_DDR DDRB
#define LED_PORT PORTB
int main(void) {
// -------- Inits --------- //
DDRB |= 0b00000001; /* Data Direction Register B:
writing a one to the bit
enables output. */
// ------ Event loop ------ //
while (1) {
PORTB = 0b00000001; /* Turn on first LED bit/pin in PORTB */
_delay_ms(1000); /* wait */
PORTB = 0b00000000; /* Turn off all B pins, including LED */
_delay_ms(1000); /* wait */
} /* End event loop */
return 0; /* This line is never reached */
}
Usando avrdude, el código se carga en el chip con la siguiente salida detallada. El LED no se enciende como se esperaba, pero parpadea brevemente cuando el código se carga en el chip.
