7.8 I

C-to-USB Bridge Kit

The CY3240-I2USB kit allows you to test, tune, and debug hardware and software by bridging the USB port to I

Populated with the CY8C24894 PSoC device, a wide variety of devices can be connected to the PC using this bridge

including:

 EEPROMs

 Real-time clocks

 ADC/DAC converters

 LCD displays

 Regulated DC/DC converters

 Port expanders

 Other devices incorporating the I

C interface

The number of devices that can be connected is constrained only by the I

C address limit and physical ability of the

C bus.

7.9 Debugging/Data Viewing Tools

Software tools are available for data viewing, debugging, and tuning CapSense applications. These tools can help

you monitor critical data, such as raw counts and CapSense parameters.

The debugging and data viewing tools are:

 Bridge Control Panel

 MultiChart

For more details on the tools, see the application note AN2397 – CapSense Data Viewing Tools.

7.9.1 Bridge Control Panel

Bridge Control Panel is a software tool used with CY3240 USB-I

C Bridge to enable communication with I

C slave

devices. The software tool is used to configure I

C devices as well as acquire and process data received from I

slave devices. The Bridge Control Panel helps in optimizing, debugging, and calibrating the target applications.
