@fbritop I would put a delay(100); in the Loop:
You can get a race condition where the scan time is shorter than the esptool reaction and it could be "too busy" to stop and upload.
If this is the case it will take some finagling to reset the upload mode.
Usually just pressing the reset key on the top side, at different times until you get in time.

@bstafford the on-board ADC of the ESP32 is notoriously inaccurate!

@iamliubo can someone from M5Stack please check the AtomS3 GitHub “Issues”.
I have one outstanding and another question to ask, but no one is there?

You should raise an Issue over on the M5Stack Github page,

@kk likely 0-60, as is the standard core basic and core2.
LCDs malfunction and possibly freeze damage below 0.
Cannot withstand condensating environment.

@ajb2k3 My StickCPlus with the dead battery will not boot with the servo attached, and, will crash if you add it while running!
Are replacement batteries available do you know? EDIT> it is a common battery with many sources > Otherwise I will try installing a large cap in the battery are that is charged by the USB, not controlled by the AXP power chip.
StickCPlus comes apart very easily, but cut the hat I/O decal to slide it out.

@kylebuttress Well, what an evening!
Does your battery work? Will it boot on battery only?
Some of my newer StickCPlus units will run the servo. One has a very good battery and will run the servo without USB! One will run the servo on USB but not battery only, one ( the one I tried 3 hours ago) will do exactly as yours. No way will it run the servo.
So I think this is my answer!
Cheers, Terry

@teastain OK, I tried to check this out and something is very wrong.
Please wait while I investigate!
Mine crashes too!

@kylebuttress If you will notice that under your thumb there are three "Hat" connections...you can plug the servo directly, pin for pin, into this and set the LEDC or other servo library to output #26. Try this as a test!

@margel the display does not refresh when new text appears and this requires a black “blanking” background.
