2.2 Running the built-in demonstration
The board comes with the demonstration firmware preloaded in the Flash memory. Follow
the steps below to run it:
– Check jumper position on the board, JP1 on, CN3 on (Discovery selected).
– Connect the STM32F4DISCOVERY board to a PC with a 'USB type A to Mini-B'
cable through USB connector CN1 to power the board. Red LED LD2 (PWR) then
lights up.
– Four LEDs between B1 and B2 are blinking.
– Press User Button B1 then MEMS sensor is enabled, move the board and observe
the four LEDs blinking according to the motion direction and speed.
– If you connect a second 'USB type A to Micro-B' cable between PC and CN5
connector then the board is recognized as standard mouse and its motion will also
control the PC cursor.
