This is a configuration example for the BMP180 barometer sensor. This
sensor works with I2C, you need to do the next connections:
BMP180 VIN -> Board 3.3V
BMP180 GND -> Board GND
BMP180 SCL -> Board PB6 (Arduino header D1)
BMP180 SDA -> Board PB7 (Arduino header D0)

BMP180 SDA -> Board PB7 (Arduino header D0)
This example is configured to work with the USBNSH instead of UART NSH, so
the console will be shown over the USB_OTG1 connector.

On the console, type "ls /dev " and if the registration process goes fine,
you should see a device called "press0". Now execute the app
BMP180 to see the ambient pressure value.
DAC:
---
This is a configuration example to use the DAC1 of the board.The DAC1 is attached
to the PA4 pin (Arduino header D10).
This example is configured to work with the USBNSH instead of UART NSH, so
the console will be shown over the USB_OTG1 connector.
On the console, type "ls /dev " and if the registration process goes fine,
you should see a device called "dac0". Now execute the app
dac put a value at the output.
