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.

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''?
