CoreS3 sleep and wake related APIs and example programs.
#include <M5Unified.h>
void setup(void) {
auto cfg = M5.config();
M5.begin(cfg);
M5.Display.setTextColor(GREEN);
M5.Display.setTextDatum(middle_center);
M5.Display.setFont(&fonts::FreeSerifItalic18pt7b);
M5.Display.setTextSize(1);
M5.Display.drawString("Touch", M5.Display.width() / 2,
M5.Display.height() / 2 - 60);
M5.Display.drawString("to sleep", M5.Display.width() / 2,
M5.Display.height() / 2 - 20);
M5.Display.drawString("After 5s", M5.Display.width() / 2,
M5.Display.height() / 2 + 20);
M5.Display.drawString("Wakeup", M5.Display.width() / 2,
M5.Display.height() / 2 + 60);
}
void loop(void) {
M5.update();
if (M5.Touch.getCount() && M5.Touch.getDetail(0).wasClicked()) {
M5.Power.timerSleep(5);
// M5.Power.timerSleep(const rtc_time_t& time);
// M5.Power.timerSleep(const rtc_date_t& date, const rtc_time_t&
// time);
// M5.Power.powerOff(); shutdown
}
}After successful upload, you can trigger sleep mode by touching the CoreS3 screen. When you touch the screen, the device will enter sleep mode and automatically wake up after 5 seconds.
The CoreS3 power section uses the Power_Class from the M5Unified library. For more related APIs, please refer to the documentation below:
