Hi,

I am new to M5Stack and I tried to make a quick setup with a AtomS3R + RFID Unit + Dual Button Unit. I am using UIFlow 2.

So far I was able to make some "hello world" setup where only one unit was connected to the AtomS3R (1: AtomS3R + Dual Button 2: AtomS3R + RFID Unit). These setups worked right from the start.

Now I want to connect both Units (Dual Button + RFID Unit) to the AtomS3R. But the code crashes. I tried different cabling options / coding options (with Pa.Hub or Groove Hub). No matter what I do, there is always a code error.

So before starting to discuss my code / cabling here, my question is:

Is it generally possible to connect more than 1 I2C unit to an AtomS3R ?

Thanks!
