Detailed Description

Manage the LEDs with blinking possibility (timer2).

Here we use the agenda solution to make the LED blinking.

A little exemple for LEDs blinking with agenda (all LEDs blink with 100ms delay)

Warning:

this program uses the e_blink_led(void) function.

 #include <p30f6014A.h>
 #include <motor_led/e_epuck_ports.h>
 #include <motor_led/e_init_port.h>
 #include <motor_led/advance_one_timer/e_led.h>
 #include <motor_led/advance_one_timer/e_agenda.h>
 
 int main(void)
 {
        e_init_port();
        e_activate_agenda(e_blink_led, 1000); //blink with 100ms
        e_start_agendas_processing();
        while(1) {}
 }
