@felmue: Thanks for your help

@fosouza Thanks! It took some quick-clicking, but I got the 2.0.5 installed.

@felmue Thanks for you fast reply Felix! I will.

@mwright Have you tried visiting Micropython.org? These is an esp32 sub forum that has a few M5Stack members in it.

Hello @Slartibartfast not ideal, but you could try the following: while your M5Stack application is loaded in UIFlow, get the rectangles, circles and triangles definitions from the python view. E.g. rectangle0 = M5Rect(35, 38, 30, 30, 0xFFFFFF, 0xFFFFFF) circle0 = M5Circle(93, 95, 15, 0xFFFFFF, 0xFFFFFF) triangle0 = M5Triangle(137, 120, 106, 149, 166, 149, 0xFFFFFF, 0xFFFFFF) then switch to M5Core2 and add those definitions together with: from m5ui import * screen.set_screen_bg_color(0x000000) into an Execute Code block at the beginning of your M5Core2 application. E.g. If you programmatically changed those shapes you probably need to put those commands into Execute Code blocks as well. I guess one alternative is to stay in the Python view altogether or to use the shapes from the M5Core2 Graphic section. Thanks Felix

Felix, Thanks for the reply. About an hour or so after setting up the Arduino tools for the M5 Stack, I downloaded the M5Tough repository with a Zip file and extracted to the Arduino libraries and came across and recognized the "Factory Test" as the "M5TOUGH TOOLS" source code. Where that code was in the M5Tough-master Then when trying to compile it, I found I also had to download and drop in the code from github for M5Unified-master, M5GFX-master to get the build to complete OK. While at it, I also downloaded the M5Stack-master for other examples as well. With building the Factory Test program, I was able to go back and forth between "Hello World" and the Factory Test, so I'm a happy camper. One thing I did notice is that Factory Test program is quite extensive and for some reason, when I did a "Save as" to try and make modifications, it no longer compiled (looks like maybe some path/setup issue in looking for files). So I'll try and solve that some other time, I'm up and running now and so far, I like what I see. Thanks and best regards, Alan

Hi, You wrote: Once the M5Stack is powered off, only the CAN information can no longer be read. So the solution is easy: Power ON the M5 device! Or do you mean OTHER devices on the same CAN are not able to read data WHILE M5 is OFF? In this case it might be possible that the CAN transceiver in the Commu is still powered (check that!) but miss the input signal. According to the datasheet of the CAN driver chip the bus output is dominant while TXD and S pins are LOW. This blocks the communication of other devices. It may help to solder the pin 8 of the transceiver to +3.3V instead of GND to enable silent mode (switch it to Rx only) or make sure the commu is not powered. The bus driver is then going to float (Off Mode) and should not block the communication anymore.
