I'd suggest looking for an I2C pressure sensor. Reading data from it would
be real easy (with either Per Finander's I2C drivers or the MBus drivers).
If there are no such parts, a pressure sensor that gives an analog output
could be hooked to an I2C A/D converter and the converter could be read
with a set of I2C drivers. There's really no need for a microcontroller.
