Right, OK, nobody panic! There is a bug somewhere that causes a random boot loop to appear in the ESP32 and strangely I had this with a Stamp the other weekend. Disconnect everything and leave the controllers unconnected for a while, cold boot the computer and try and flash UIFLow firmware.

I saved a copy of the IP5306_I2C data sheet from a long time ago. In this table, I see the charge current can be set by the CHG_DIG_CTL0 register (see the formula). I would assume the M5stack designers took care of setting the max charge current with that register bits 0 through 4, though I could be wrong. If you want the entire data sheet, let me know.

you could ignore the version notice. just select the core2 device on the setting page will be ok. 1.0.12 was for the Desktop IDE software version. 1.4.5 or 1.6.x was for the UIFlow firmware version.

Hey @kabron I have never met this phenomenon yet

hi, wich ino file I have to upload to visualize "thermal distance?

To whom it may be interested I modified native arduino M5STACK library to suite both M5STACK and ODROID-GO. Look in the examples folder. Also read comments in M5Stack.h Tested with VisualMicro for Visual Studuo https://yadi.sk/d/0wo7ympO3Zc6RT

@dimi 在 FACES UI Lessons question 中说： The information in the previous lesson, today is not relevant. So, these lessons only misinform us. So I ask, what is the use of them? It is better to rewrite or delete them.
