@Edoardo_27 have you tried official examples: https://uiflow-micropython.readthedocs.io/en/latest/module/bala2.html https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Application/Bala2

Hello @peolsolutions just an FYI: M5Stack Fire doesn't have an AXP192 PMU. I get the feeling some of your posts are AI generated, no? If I am correct I'd appreciate if you could first verify the technical facts before posting. Thank you very much for your understanding. Thanks Felix

For compiling the firmware from the M5-PbHUB-Internal-FW repo, try using the Arduino IDE or PlatformIO. Both are open-source and offer a more modern experience. You can also use the command line with PlatformIO, which is pretty flexible.

@kuriko ESPtool is a nightmare to use, I know I have tried. We need an Arm64 port for the Raspberry Pi

Hello @wsanders I think these compiler error have been fixed (see here), but after tagging the library. I guess it will be in M5Unified 0.2.4. Thanks Felix

@SadE54 I believe it is.

as long comport is visible when M5Dial is connencted then you should be able to reload firmware or just use one of Easyloader samples from M5Dial documents web page

Hello @wsanders you answered your question yourself - power off functionality is not implemented yet on M5PaperS3 and therefore RTC alarms do not work. Some background (as I understand it). Some M5Stack devices - like M5Paper (non S3 version) - can not power off while being powered from USB so the current code in Power_Class does the following: it sets up both, RTC alarm and ESP sleep functions (e.g. deep sleep and light sleep). It then first attempts to power off - which works when powered from battery, so the code execution ends here. However when powered from USB, power off does nothing and the 'backup' ESP sleep functions take over. So with M5PaperS3 and the current state of Power_Class when you call timerSleep(int seconds) it works because ESP sleep function is setup and can take over. However when you call the other timerSleep() functions nothing happens as the ESP sleep functions are not setup here and power off isn't implemented yet. And when you call setAlarmIRQ(30) and powerOff() manually nothing happens either - same reason again - power off is not implemented yet. BTW: you can still test your code though - during the 30 seconds you can double-click the side button to actually power off M5Paper and when the time is up it should power on again. Thanks Felix

@mukul_100_ i would recommend to study some of YT VolosR examples of his approach to UI

@felmue it works,great. thank you felmue.

@DumpsterFire add a screen rotation 90 degree builtin statement, download and test again.

@ajb2k3 When you have a moment, I would really appreciate your thoughts or any updates you might have.

@kuriko I'll check and let you know! Thanks for the response!
