How can i initalise the states and cause this state machine of 3 states to work effectively.
My code if found below:
# include <stdio.h># include <io.h># include <system.h># include <alt_types.h># include "altera_avalon_pio_regs.h"
int main()
{
alt_u32 key_in, signal_raknarvarde, state;
# define Scan_keys_state 0x01
# define write_to_leds_state 0x02
# define no_keys_state 0x03
// Initiering av variabler och utsignaler till hårdvaran
//int state = Scan_keys_state;
//int state = write_to_leds_state;
//int state = no_keys_state;
// loop for ever
while(1)
{
switch (state) {
case Scan_keys_state:
// if key_in, state = write_to_leds;
state = write_to_leds_state;
break;
case write_to_leds_state:
state = no_keys_state;
break;
case no_keys_state:
// Kolla att ingen knapp är nertryckt,
//denna function kan göra att //wait(time); inte behövs
state = Scan_keys_state;
break;
}
}
return 0;
}

Thanks for the help in advance
