In the future, it may be * possible to handle more precise computation by sending the harmonics * coeficients of the tides over IR. * * To configure the face, long press the Alarm button to enter the setting mode * then set the time of the high tide in your area. You can move the hour using * the Alarm and Mode button to go up and down, then press the Light button to * set the minutes in the same way. Notice that if you overflow the minutes then * the hour will change. Similarly, when the hours overflow, the day for the * tide (shown in the upper right corner) is changed too (however there is no * direct way to set the day). You must be sure to select the right day for the * tide that you are currently entering. * Note that, if you set the high tide value for a day with a full or new moon, * the computation will be slightly more precise. * Because the Mode button is used, you must first press the Alarm button once * or twice, to exit the settings, before pressing Mode to exit the watch face. * * Once configured, the face start by showing the state of the current tide * (low, flowing, high, or ebbing) at the top of the screen. If the tide is * flowing or ebbing, the bottom left part of the screen also shows the current * hight of the tide as a percentage of the total tide. The bottom right portion * of the screen shows a representation of whether the current tide is a neap * or spring tide, or an intermediate one. * * You can then repeatedly press the Alarm buttom to see the time of the future * high and low tides. The bottow right corner has the same representation of * the amplitude of the tide and the top right corner has the day of the month * for which the tide is shown. * * You can long press the Light button to come back to the state of the current * tide. Exiting and re-entering the watch face will have the same effect. */ void tide_face_setup(uint8_t watch_face_index, void ** context_ptr); void tide_face_activate(void *context); bool tide_face_loop(movement_event_t event, void *context); void tide_face_resign(void *context); #define tide_face ((const watch_face_t){ \ tide_face_setup, \ tide_face_activate, \ tide_face_loop, \ tide_face_resign, \ NULL, \ })
