  Hi @heybin ! What do you want to show us with the picture: flickering due to problems with contacts? Do you know what the meaning is of: flashing? ( = 1s on > 1s off > 1s on > and so on: charging?) continiously OFF? continiously ON? What I noticed so far: a) USB charging cable connected to M5GO CHG Base and M5GO CHG Base attached to M5GO Base: LED is flashing and obviously charging b) M5GO disconnected from M5GO Base: LED = ON for 30 seconds , than OFF, but FIRE is still on and operational (Power from internal Lipo Battery?) c) M5GO CHG Base attached to M5GO Base, but no power on USB-Cable: same behaviour as item b) above. (Power from internal Lipo battery AND/OR CHG Base Battery?) For a) and b) so far, I didn't test, for how long the FIRE stays ON.

  @grelm I'm glad I can help. Just needed to rule out the basics before blaming the hardware. Glad it turned out to be a bug in the software.

  @ipodlux If it's not connecting to the device, what errors do you see? Paste your command line output here and maybe I can help further. One other custom I did for ampy... I created the file ~/.ampy with these contents: # Example .ampy file # Please fill in your own port, baud rate, and delay AMPY_PORT=/dev/tty.SLAB_USBtoUART AMPY_BAUD=115200 # Fix for macOS users' "Could not enter raw repl"; try 2.0 and lower from there: #AMPY_DELAY=0.5 If you create that file, you will not have to pass the port and baud rate options when running the ampy command. This is the standard way to run ampy when you don't have the .ampy file created. world101$ ampy -p /dev/tty.SLAB_USBtoUART -b 115200 ls /flash Also, I was mistaken on the the v1.2.3 firmware with the beeps disabled by default. I just flashed one of my cores with the M5Burner and the beeps are there. I must have been running a custom firmware before.

  @ajb2k3 Thanks a lot ! @cepics "A custom ESP-WROOM-32 build without any flash chip added, so the existing GPIO6, GPIO7, GPIO8, GPIO9, GPIO10 and GPIO11 pins can be used to allow us to add a GD25Q127C (or similar) on our external circuit."

  @kat @Rop you need to create and M5ez project, create a text place holder and set the code to replace the text with the values. Hopefully @Rop will pick up the notification and help you out. My knowledge is more towards Uiflow

  Currently there is no support for png images in the micropython port that form the firmware of the m5Stack range. BMP is its raw uncompressed state is a simple file to translate along with base level jpg (not JPEG!) Until such time that a codec exist for micropython, we are all stuck with converting graphics into base level formats.

  @rob-biernat which M5Stack or Stick are you using? The M5Stacks and Sticks have an I2C grove port (port A) but this is also a digital I/O port in that it can read or write 0 or 1 values (on or off) I am currently triggering a relay unit from the port. The M5Go base has has 2 additional port which are multi I/O (port b) and UART (port C) Unlike Arduinos, the esp32 which powers the M5Stack has no set pin functions and all pins can be used for a range of functions. When using Port A Yellow is SCL (pin 22) and white is SDA (pin 21) and need to be defined. I have started to document the different functions of the grove connector and you can find them on pg 19 and 20 of my WIP book here https://github.com/Ajb2k3/UIFlowHandbook/blob/master/UIHB1404192.pdf

  @lukasmaximus Thanks Lukas. I had posted in another subject. The desktop ide does not allow me to create variable. I see the icon put does not open the pop up screen to name the variable.

  @joeybab3 It seems those libraries you used are designed for Arduino Chip which has been defined A0. So you need change those libraries sources so that they are compatible with ESP32 chip.
