  • GPIO startup state


    I have a problem with the initial state of the GPIO pins which seems to be at '1' for some time. Is it possible to start with a '0' ?

    usually with microcontrollers, default state is high impedance, thats why it may be 0 or 1, you can verify by diablo datasheet

      Well, it seems that there is a '1' for some times because I put a pull down on the output... :-(

        At the end, I solved the problem. This comes from the PWM_Init call on this pin. Even with a parameter of 0 for the cycle, I got a '1' for some time...
