Hello all,
Now we have a trial production of a machine, the button did not interrupt to come;The button did not respond for a period of time under 1.8v voltage.The IIC communication is normal, and the interrupt pin is always low (no button is pressed) when there is a problem.The host does not initiate I2C communication when it is interrupted.Use 1.8v on one end of the multimeter current range, and connect the interrupt pin on the other end. After an instantaneous current of more than 10 milliamps, the circuit will return to normal, and the interrupt pin level will be higher
