      Hi

      I have the Pa Hub (PCA 9548AP). WHen I plug it into the Core S3 it registers it's address and shows up on the i2c bus but anything plugged into it doesn't. The units work fine directly connected though. I.e. code works on sensor directly plugged in but does not when the hub is used and the sensor is plugged into that. Do I need a driver or am I doing something wrong?

        @Bipman What sensor are you trying?

          @teastain I've tried the BME280, the heart rate monitor, the OLED Unit to name a few.

            Hello @Bipman

            you probably don't need a PaHub for your setup.

            If the I2C units you want to connect all have different I2C addresses a simple Grove hub is enough.

            PaHub is only required if you want to connect I2C units which share the same I2C address.

            Thanks

              PaHub can be used as simple hub as long as no connected unit is using its I2C address of 0x70.

              See example in UIFlow2 Project Zone: M5Core_PaHub_As_Simple_Hub_UIFlow2.1.5

              Thanks
