Hello everybody,
I wonder if someone has already tested the I2C communication to a device that communicate with an I2C bus with voltages in the range 1.71V to 1.95V.
Should I add a circuit to adapt tension to 3.3V for the Teensy input?
 
I'm trying to interface teensy with ICM-20948 (I still don't have this chip), previously I was using the MPU9250 that is going out of stock. The chips are pin-to-pin compatible, except that VDDIO is changed from the range [1.7V - 3.5V] to [1.71V - 1.95V]. I've not found anywhere if teensy can dialogue to ICM without adapting the voltage. Anyone knows it?
 
Hm. Or, try to connect the needed pull-up resistors with vddio, not 3.3v.
But I'm not sure if that works.
 
Ok, thanks, I will do the same. I was just wandering if I can use the same PCB I've already made for MPU9250.
