CHAPTER 4: ANAVI IoT GNU/Linux Distribution
Anavi IoT GNU/Linux distribution is still
under construction
. It is built using the Yocto Project
Yocto Project and OpenEmbedded
OpenEmbedded and features daemon that sends data from the
sensors and receives messages through the lightweight machine-to-machine communication protocol MQTT
MQTT. There is also a responsive HTML5 web interface
developed with jQuery Mobile and Node.js
Node.js API. For more details visit:

The sensors that can be connected to ANAVI Infrared pHAT communicate with a host microcontroller via a communications standard called I2C
I2C (Inter-Integrated-
Circut). I2C uses two wires, labelled SDA (Serial Data) and SCL (Serial Clock). To function properly, I2C requires a pullup resistor on each of those lines therefore
ANAVI Infrared pHAT includes two 4.7kohm resistors labelled as R6 and R7. If for one reason or another you need to disable the I2C pullup resistors remove R6 and
R7.
