[Tom-GARNIER]

Hello, I had a problem with InternetCE: when I open the internet program on my calculator, either (with my program, it's only the minimal.c example) the screen is white, and I need to press a key to exit (the first time it reset my calculator), either (with the program sent in another issue by @MathisLav ), the screen display "Web connecting ...", and I couldn't do something as long I reset. I twice case, my phone didn't detect the USB (to use USB Modem sharing) (I have a samsung on android 11), and my computer neither (I didn't know how to do usb tethering on windows. Can you help me? Thanks You
