AXP192
AXP192 is a highly integrated power system management chip. A series of power chips are packaged in the M5Core2 library to control the power of peripheral peripherals.
SetLcdVoltage()
Syntax：
void SetLcdVoltage(uint16_t voltage);
Description：Set screen voltage, adjust brightness, valid range of parameters is 2500-3300
Example：
#include <M5Core2.h>
void setup() {
M5.begin(); //By default, "M5.begin()" will initialize AXP192 chip
M5.Lcd.fillScreen(RED);
}
void loop() {
M5.update();
for(int i=2500; i<3300;i++){
M5.Axp.SetLcdVoltage(i);
delay(10);
}
for(int i=3300; i>2500;i--){
M5.Axp.SetLcdVoltage(i);
delay(10);
}
}
SetLed()
Syntax：
void SetLed(uint8_t state);
Description：Set the built-in LED light, state: 1 is on, state: 0 is off
Example：
#include <M5Core2.h>
void setup() {
M5.begin();
}
void loop() {
M5.Axp.SetLed(1);
delay(1000);
M5.Axp.SetLed(0);
delay(1000);
}
