Function Documentation

void hl_application_changed	(	keyscan_t	key,
		gps_parser_t *	hlparser
	)

Event handler for switching through applications.

This function is called whenever the active application changes. General app switching stuff should be done here. For app specific tasks an appropriate function has to be called.

{
        // clear application display area
        hl_clear_application_screen ();
        // clear and enable status bar
        hl_stb_init ();
        hl_menu_clear_s4 ();
        hl_menu_clear_s5 ();
        hl_menu_clear_s6 ();
        hl_menu_clear_s7 ();
        hl_menu_clear_s8 ();
        hl_menu_clear_soft (HL_MENU_SOFTKEY11);

  switch (app_state) {
  case APP_POI:
    hl_init_poi_app (key, hlparser);

void hl_handle_menu_key	(	keyscan_t	key,
		gps_parser_t *	hlparser
	)

Key handler for menu keys.

Default key handler, to be called first. General menu keys for switching applications are evaluated here. All other key presses are passed to the specific key handler function of the currently selected application.

  uint8_t ok;

  switch (key) {

    hl_application_changed (key, hlparser);
