Not everyone uses UIFlow ;-)

@m5hans I have similar experience. I can run all examples and my programs, but sometimes the M5Paper freezes just after restart. It helps me to send it just again. Try to send the examples few more times if it helps. The Factory test and few more expamples are made in VSCode. It could be possible to change the sources for Arduino, but I would suggest you to try VSCode. The IDE is bettere and compilation faster and it is not difficult.

@felmue Oh, I find your Knowlegbase at https://www.gwendesign.ch/kb/m5stack/index.html. Great work! Thank you very much for creating it! It is a shame, they designed it, that it takes 2.5 mA from battery in deep sleep :( It is very sad for ePaper product.

@felmue Thanks. Did you measure the current in DeepSleep mode? I am getting only about 50-60 hours of life time when getting out of deep sleep for about 12 s (downloading some JSONs from the cloud) and then going back to deep sleep for about 5 mins. It should last much longer with 3.7/390mAh battery in my calculations.

@felmue Thank you. The overview schematic is not complete and dos not contain enough information.
@m5stack It is very hard to develop anything for your devices if your libraries are incomplete, buggy and poorly documented (sorry, but they are) and the detailed schematic is non existent. Either create a working libraries or allow people to do it themselves, which is really hard without schematic. Without this I cannot use your devices in my projects (I have thousands of users, who buy your products just because of my projects). I do it for free asn Open Source. I am excited with all new product and I am also big evengelist for the M5Stack, but with more and more products I spent tens of hours just by finding how it works and I am starting to be frustrated from it. Sad.

Is it possible to recognize if CoreInk runs on battery or on USB-C power? Is there detailed schematic anywhere?

@felmue Do you have CoreInk schematic? I cannot find it. Eg. pin 35 seems to be used to measure battery voltage in samples, but no word in docs. Also DeepSleep seems to be supported in some newer unreleased libraries and does not work whne CoreInk is on USB power.
