Original Gravity: Digital Capacitive Touch Sensor For Arduino – PartsCountry

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.
