@ajb2k3 I learned that the browser does connect to the Core2 by WiFi and the IDE connects using USB.

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

Hello @Marelli7 you are welcome. I sounds like you are having fun. And thanks for reporting back. I am glad to hear you got it working to your liking. Thanks Felix

@felmue, thanks, also for the ```-tip!! After years of programming the ESP32 it takes a lot of time to get familair with the Core2 specifics

Yes and no. UIFlow uses micropython which runs off the controller. Arduino uses a C/C++ cross which wipes the micropython each time.

I've been working in raw I2C write and M5Stack have told me that there is an issue with digital read functions with the EXTIO2 and the Stamp EXTI/O but won't tell me where the error is? Be careful when reading and writing to the EXT2 StampEXT as it is very easy to corrupt the I2C address register.

@felmue Thnx! found what I was looking for.
