Works. Thank you!

No, it's not just the forum. docs.m5stack.com doesn't work.
The site won't reply to ping. It's a network problem.

Hi.

I'm having trouble accessing these websites:
docs.m5stack.com
forum.m5stack.com
community.m5stack.com

I live in Romania. I tried broadband internet connection and mobile phone.
Ping doesn't work.
DNS resolves to 120.77.157.90 for all of them.

m5stack.com (the main site) works, but that's a very different IP: 23.227.38.32.

The only way I could enter this forum was to use TOR, but even that didn't work very well. There were lots of timeouts.

Can you investigate?
Thanks!

Hi.
It seems that M5.Axp.ScreenBreath() crashes when it is used in a interrupt. Try the demo below in Arduino IDE. It should turn off the display after a timer delay and turn it back on when the button is pressed.
On my system this program crashes with a watchdog timeout during i2c operation.

#include <M5StickC.h>  //define M5StickC hardware components and functions
#define BUTTON_MAIN 37  //The main button pin number
#define SCREEN_TIMEOUT 10 //Screen-off timeout in seconds
hw_timer_t *timer;

void IRAM_ATTR onButton() { //Interrupt on button press => turn on the screen
 detachInterrupt(BUTTON_MAIN); //Ignore more button presses
 M5.Axp.ScreenBreath(10); //Set screen light ON
 timerAlarmEnable(timer); //Start timer for screen-off delay
}

void IRAM_ATTR onTimer(){  //Interrupt on timer => turn off the screen
 timerAlarmDisable(timer); //Stop the timer.
 M5.Axp.ScreenBreath(0); //Set screen light OFF
 attachInterrupt(BUTTON_MAIN,onButton,FALLING); //Attach interrupt on button press => turn on the screen
}

void setup() {
M5.begin(); //Init M5
M5.Lcd.fillScreen(YELLOW); //Make screen yellow
pinMode(BUTTON_MAIN, INPUT_PULLUP); //Button GPIO set as input, pull-up enabled
timer=timerBegin(1,40000,true); //Init screen light timer, divisor 40000 => 0.5ms steps
timerAttachInterrupt(timer,&onTimer,true);  //Set screen light timer interrupt function
timerAlarmWrite(timer,SCREEN_TIMEOUT*2000,true); //Set interrupt to turn off screen after X timer steps of 0.5ms each.
timerAlarmEnable(timer); //Start timer for screen-off delay
}

void loop() {
  //No code here.
}
