If you feel like the canvas method is too much effort - especially if it part of a larger project or you prefer M5GFX - then here is a working switch in M5GFX: import os, sys, io import M5 from M5 import * import time Switch1 = None Switch2 = None Switch3 = None Knob = None state = None touch = None # Describe this function... def Off(): global state, touch, Switch1, Switch2, Switch3, Knob state = 0 Knob.setCursor(x=145, y=119) Switch1.setColor(color=0x999999, fill_c=0x999999) Switch2.setColor(color=0x999999, fill_c=0x999999) Knob.setColor(color=0xffffff, fill_c=0xffffff) # Describe this function... def On(): global state, touch, Switch1, Switch2, Switch3, Knob state = 1 Knob.setCursor(x=174, y=119) Switch2.setColor(color=0x33ccff, fill_c=0x33ccff) Switch3.setColor(color=0x33ccff, fill_c=0x33ccff) Knob.setColor(color=0xffffff, fill_c=0xffffff) def setup(): global Switch1, Switch2, Switch3, Knob, state, touch M5.begin() Widgets.setRotation(1) Widgets.fillScreen(0x222222) Switch1 = Widgets.Circle(174, 119, 14, 0xa4a4a4, 0xa4a4a4) Switch2 = Widgets.Rectangle(145, 105, 28, 28, 0xa4a4a4, 0xa4a4a4) Switch3 = Widgets.Circle(145, 119, 14, 0xa4a4a4, 0xa4a4a4) Knob = Widgets.Circle(145, 119, 14, 0xffffff, 0xffffff) Off() def loop(): global Switch1, Switch2, Switch3, Knob, state, touch M5.update() touch = M5.Touch.getCount() if touch != 0: if (M5.Touch.getX()) >= 131 and (M5.Touch.getX()) <= 188 and (M5.Touch.getY()) >= 105 and (M5.Touch.getY()) <= 133: if state == 0: On() else: Off() time.sleep_ms(500) if __name__ == '__main__': try: setup() while True: loop() except (Exception, KeyboardInterrupt) as e: try: from utility import print_error_msg print_error_msg(e) except ImportError: print("please update to latest firmware")
