C language

This first example available in the Playground gets data from gyro, accelerometer, magnetometer, barometer and GPS and shows them on the console terminal.


To compile it probably you need to install the C++ compiler and Make utility by typing:

debarm:~# apt-get install g++
debarm:~# apt-get install make

Then launch the C++ compilation by typing:

debarm:~# cd playground/c/daisy7                                                
debarm:~/playground/c/daisy7# make clean
debarm:~/playground/c/daisy7# make

Now launch the data acquisition from the Daisy-7 sensors (insert the Daisy-7 on Daisy D1 connector):

debarm:~# ./main
