Pytrack I2C Error when polling button_pressed()



  • Hi,

    Running a script that effectively is in a polling loop waiting for a button press to start a logging application. The loop reads the button on the Pytrack board constantly. Within the loop the RTC is read once every minute.

    After one or two hours an I2C Bus Error occurs when button_pressed() is called. What could be the cause of this?

    By the way: Is the button_pressed() the result of a debounced input?

    I need to rewire the switch using a switch directly on the GPIO and not via an I2C interface. Using I2C Is is not be very power efficient.
