#include <M5Unified.h> void setup(void) { auto cfg = M5.config(); M5.begin(cfg); M5.Display.setTextDatum(middle_center); M5.Display.setTextFont(&fonts::FreeSerifBold9pt7b); M5.Display.setTextSize(1); M5.Display.drawString("Press BtnA", M5.Display.width() / 2, M5.Display.height() / 2 - 20); M5.Display.drawString("to Sleep 5s", M5.Display.width() / 2, M5.Display.height() / 2 + 20); } void loop(void) { M5.update(); if (M5.BtnA.wasPressed()) { M5.Display.clear(); M5.Display.drawString("Sleep 5s", M5.Display.width() / 2, M5.Display.height() / 2 + 20); M5.Power.timerSleep(5);//sec } }Since there is no independent RTC chip, The Fire cannot use RTC-related functions and can only implement second-level timed wake-up as demonstrated in the example program.
The example program runs as follows:
API
M5GO Power section uses the Power_Class in the M5Unified library. For more related APIs, you can refer to the following document:
