Live Embedded Event. at Live Embedded Event. The ./build is a script to build Wiring Pi from the source files. Found a problem? This number Also, when dealing with I2C issues, I often find that I need to re-acquaint myself with the source spec: If that input is not used as the reference voltage, it uses the supply voltage as the reference voltage. How to compile: $ make -C /tools/iio ARCH=arm Regarding the third code, it is the code from the source and you shouldn't compile it because it doesn't have a main function. This tutorial is the second in a four-part series on the communication protocol I²C; explaining what it is, how it works and how you can use it on your Raspberry Pi. value = (value & vmask) | (oldvalue & ~vmask).
