• First tests

  Ethon • 11/16/2015 at 15:06 • 0 comments

  After an while we received most of the components and soldered them all together. Now we are testing some of the basic functions and die IO's of the board.

  At the picture you can see the first test, to toggle a LED with a button by using ASF.

  Code:

  #include <asf.h>
  #define LED PIN_PA08
  #define BUTTON PIN_PA09
  void stepup_pins(void)
  {
   struct port_config pin_conf; // create struct
   pin_conf.direction = PORT_PIN_DIR_INPUT; // set to input
   pin_conf.input_pull = PORT_PIN_PULL_UP; // set to pullup
   pin_conf.powersave = false; // set not to powersave
   port_pin_set_config(BUTTON, &pin_conf); // configure pin PAxx
   pin_conf.direction = PORT_PIN_DIR_OUTPUT; // set to output
   pin_conf.input_pull = PORT_PIN_PULL_NONE; // set not to pullup
   pin_conf.powersave = false; // set not to powersave
   port_pin_set_config(LED, &pin_conf); // configure pin PAxx
  }
  void main(void)
  {
   system_init();
   stepup_pins();
   while (true) 
   {
   bool pin_state = true;
   pin_state = port_pin_get_input_level(BUTTON);
   port_pin_set_output_level(LED, !pin_state);
   }
  }
