As no one Answered. I have a MS5637 barometric sensor on the Tab5 through the Port.a.

The configuration that i used to communicate with it was these:

M5.Ex_I2C.begin(); // Initialize I2C for MS5637 with SDA=GPIO53, SCL=GPIO54
Wire.begin(M5.Ex_I2C.getSDA(), M5.Ex_I2C.getSCL()); // Reconfigure default Wire to use M5.Ex_I2C pins
barometricSensor.begin(Wire);

I'm not even sure if everything is needed but it works.
