ON or OFF user's fingertip on the linear touch sensor.
When connecting the STM32F072 Discovery board to a PC, the LEDs LD1 (COM)
and LD2 (PWR) will light up and four LEDs LD3, LD4, LD5, LD6 are blinking.
Press the User button B1 to enable the gyroscope MEMS sensor (L3GD20). The
four LEDs will indicate the board motion, direction and speed.
Connect STM32F072 Discovery board to a PC with a 'USB type A to Micro-B'
cable through USB connector CN2 (USB USER). This converts the board to a
standard mouse. Press User button to start the USB test. Move the STM32F072
Discovery board and see the mouse move according to the board movement.
Press the User button again to enable the linear touch sensor; the four LEDs will
be ON or Off according to the position of the fingertip on the linear touch sensor.
