CoreS3 Button
CoreS3 button input related APIs and case programs.
Note:
Include
CoreS3.update() function in the main loop to read status update and minimize blocking, otherwise you may not be able to retrieve the status of key changes in time.Example
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
#include <M5CoreS3.h> void setup(void){ auto cfg = M5.config(); CoreS3.begin(cfg); CoreS3.Display.setTextColor(RED); CoreS3.Display.setTextDatum(middle_center); CoreS3.Display.setFont(&fonts::Orbitron_Light_24); CoreS3.Display.setTextSize(1); CoreS3.Display.drawString("Touch Button Test", CoreS3.Display.width() / 2, 15);} void loop(void){ CoreS3.update(); if (CoreS3.BtnPWR.wasClicked()) { CoreS3.Display.fillRect(0, 40, CoreS3.Display.width(), 70, BLACK); CoreS3.Display.drawString("Btn PWR", CoreS3.Display.width() / 2, CoreS3.Display.height() / 2 - 30); }}API
The status reading of the physical button (BtnPWR) on CoreS3 depends on the power management chip. Currently, only "wasClicked" and "wasHold" can be used normally.
