I2C

NeuralPlex includes i2c-tools as a part of the default file system build, examples of optional commands:

Command	Description
i2cdetect	detect the devices present on the I2C bus
i2cdump	dump the content of an I2C device
i2cset	write a single character to an I2C device
i2cget	read a single character to an I2C device
