I bought a couple of M5Stick C Plus a few months ago and now I want to put them into operation. Unfortunately, the battery does not charge. A 68 ohm resistor between bat and 3.3 volts does not help either.
Does anyone have a tip on this?
The voltage at PIN BAT is 2 mV. When I connect a LiIon battery there, it will be charged.
Looks like a cold solder joint. Is something like this known. It is so with all 4 tested devices.
I have accessed the M5Stick C Plus display in Micropyton with lcd.print() in the past. Suddenly this does not work anymore.
from m5stack import *
from m5ui import *
from uiflow import *
lcd.clear()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'lcd' isn't defined
Can someone explain me how to use the internal M5Stack Micropython commands again.
As IDE I use Thonny.
After a restart of Thonny, it works again.
The tip has hit the problem. I have implemented a query of the key A in the callback routine after 1 ms. Only if the key is still pressed the routine is executed. Otherwise nothing is done. Now there are no more key presses from the ghost.
Thanks

Thank you for the information.
I will have a look at the links. At first glance it might fit.

I discovered by accident that the M5Core sends out a command via MQTT, even if the associated button was not pressed at all. Has anyone ever observed something similar. What can be the reason. It only occurs with key A.
I have written a program to control my marquee in UIFlow. Here is the resulting Micropython code:
def buttonA_wasPressed():
global temp, prog_name, lfd_nummer, version, data_update, balkon, wohn_zimmer, testraum, message
m5mqtt.publish(str('whg/balkon/markiese/strg'),str(lfd_nummer))
lab_status.setText(str(lfd_nummer))
lab_status.show()
lfd_nummer = (lfd_nummer if isinstance(lfd_nummer, Number) else 0) + 1
pass
btnA.wasPressed(buttonA_wasPressed)
Unfortunately, the indentations are swallowed. Is there a way to format code?

alternativ kannst Du auch bei [https://www.distrelec.de/de/manufacturer/m5stack/man_msa?no-cache=true&page=1&pageSize=50](link url) bestellen.
Mit UIFlow 1.8.4 habe ich auch keine Probleme. Der Prefix mqtt/ ist bei mir nicht erforderlich. Lag wohl an der Version der IDE.
