    Hi!

    I have MCBSTM32,

    This board has PB8..PB15 pins which are connected to leds.

    When i configure the PB pins as Input Floating, the leds are on. WHY?

    Is it wrong that ''Input Floating'' means ''not connected''?

    Hi,

    Look at the board schematics at from Keil

    http://www.keil.com/mcbstm32/mcbstm32-schematics.pdf

    you will see that the LEDs are connected to IC6 - 74LVC244. I let you explain what you observe by yourself with some googling at this IC :-).

    Cheers,

    STOne-32.
