This is a simple system monitor of Raspberry Pi via 1602 LCD on I2c protocol.
##C++ Version
###Installation(Primarily build from source)
To use it, you have to install wiringPi libraries and enable I2C specifications via /etc/modules in Raspberian system(not in Ubuntu mate).
####wiringPi-Installation To use it, you have to install wiringPi libraries.
