## Description

I²CDriver is an easy-to-use, open source tool for controlling I²C devices and a great tool to help with quick driver development and debugging. It works with Windows, Mac, and Linux, and has a built-in color screen that shows a live “dashboard” of all the I²C activity. It uses a standard FTDI USB serial chip to talk to the PC, so no special drivers need to be installed. The board includes a separate 3.3 V supply with voltage and current monitoring. It's kinda like a Bus Pirate with a display and great Python support.It’s in every phone, in your embedded electronics, in every microcontroller, Raspberry Pi, and PC motherboard. It’s a mature technology - still going strong after 36 years. Because it’s everywhere, I²C is used by everyone from novices to embedded designers. But the common element of everyone’s I²C experience is struggle. Instead of being easy, I²C very often feels really difficult. Because there are so many ways for I²C to go wrong, things rarely "just work" and instead involve some painful debugging.While other I²C tools might offer a couple of LEDs, I²CDriver has a clear logic-analyzer display of the signal lines plus a graphical decoding of the I²C traffic.In addition, it continuously displays an address map of all attached I²C devices, so as you connect a device, it lights up on the map. You’ll never have to ask “is this thing even switched on?” again.The current and voltage monitoring let you catch electrical problems early. The included color-coded wires make hookup a cinch; no pinout diagram is required. It includes a separate 3.3 V supply for your devices, a high-side current meter, and programmable pull-up resistors for both I²C lines.There are three I²C ports, so you can hook up multiple devices without any fuss.I²CDriver comes with free (as in freedom) software to control it from: a GUI the command-line C and C++ using a single source file Python 2 and 3, using a module Comes with an assembled and tested I2CDriver board plus some jumper cables. The VEML7700 Breakout shown in the demo not included - but you can pick one up here.
