Control the I2CDriver hardware tool from your Windows PC!
The I2CDriver app provides a graphical interface to the popular Excamera Labs I2CDriver electronics test & development hardware. New users without I2CDriver hardware can familiarize themselves with the app by placing it in simulator mode.
The I2CDriver board is an easy-to-use, open source tool for controlling I²C devices over USB. 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.
I2CDriver has a separate 3.3V supply for your devices, a high-side current meter, and programmable pullup resistors for both I²C lines. The included color-coded wires make hookup a cinch. No pinout diagram is required.
