{

/* Configure the LED GPIO as an output and HIGH (On) */

hal_gpio_init_out(LED_BLINK_PIN, 1);

while (1) {

/* Wait one second */

os_time_delay(OS_TICKS_PER_SEC * 1);

/* Toggle the LED */

hal_gpio_toggle(LED_BLINK_PIN);

}

You can vary the blinky rate by adjusting the delay in 'os_time_delay' in the task handler
