Additional Information
Reading and writing a I2C packet generally follows a specific command structure. Often, one will send a structured packet to the virtual serial port with a I2C-USB command, followed by the I2C device address with address registers and informational bytes. Details and examples on usage can be found on the Technical Documentation page.
