Hey
I am using the accelerometer MMA7455, this works to 2.4 to 3.6V, while the entire board works at 5V.
To maintain the same voltages of the circuit board and accelerometer, I put the TXB0108 that is able to raise the voltage to 5V (3.3V to 5V).
By putting up the circuit I do not receive the coordinates X, Y, Z in the Display.
If not because of TXB0108 or otherwise, or should also have put other pull-up resistors on the lines between the MMA7455 and TXB0108 (B_SDA_A and B_SCL_A).
Where you could be wrong?
attached circuit diagram.
Thank you.
