added comment to avoid bug #7 in si570 frequency setting.
new driver draft for accelerometer was added.
driver reads output as separate bytes. Program returns constant wrong values:

verified reading from IMU01A accelerometer sensor. Reads data by smbus read word command.
example for IMU01A accelerometer sensor was added.
gyroscope added.
Added word read/write for CP2112 interface.
Added a motor control driver.
Added motor driver.
gyroscope reading was fixed.
driver for diff pressure sensor was added.
spaces added, shitty mechanism
atmega sensor init
avrio firmware init
Roman's CP2112 HID blinker demo code was added.
improved support for differential pressure sensor.
Added GPS setup GPS setup.
