In the example below I am using lcd-image-converter.
lcd-image-converter https://sourceforge.net/projects/lcd-image-converter/
Select 8bit or 16bit for Block size and create xxx.c.
Use M5.Lcd.pushImage(x,y,imgWidth,imgHeight,(unit16_t *) xxx);
No drivers needed for stickC and atom on linux, but you need to know what you're doing to allow access to the usb, e.g. add permission for non root user, this could be especially tricky if using linux in a virtual machine.
Hey there! I'm glad you're interested in using M5Fire and UIFlow in your workshop. It's always best to be prepared for any situation, and having a backup plan in case of no internet connection is smart. I'm sorry to hear that the UIFlow desktop download is only for Windows 10, but I might have a solution for you. Have you tried checking out websites that offer Windows 7 product key options for older computers? I found one website that has a variety of Windows 10 product key options for different devices, and it worked great for me when I upgraded my own computer.
I did erase, and M5Burner did never complain but it didn't solve the problem
I don't know why but as I tried again and again, it worked...pretty weird...
