ach ja,
und hier eine Beschreibung:
Code:# Arduino ButtonClass tButton Instances: e.g. tButton mybtn; // and perhaps more: tButton mybtn1; tButton mybtn2; // etc Init: mybtn.init(pin_number, INPUT/INPUT_PULLUP) - or - mybtn.init(pin_number, INPUT/INPUT_PULLUP, min_press_ms) (for INPUT_PULLUP mode, the press action is inverted automatically) (min_press_ms default: 60ms) to retrieve/refresh button click states: call repeatedly mybtn.click() alias: mybtn.state() it returns a int8_t value 0, 1, 2, or 3: 0: not pressed 1: 1 short click (default minimum duration = 60ms) 2: double click = 2 quick short clicks (default: within <= 150ms) 3: a long press (minimum duration= 300ms)
