Kit Operation

Wait until the USB enumeration completes successfully and the board is powered. When the USB
enumeration is successful, both the power LED and status LED light up. 

The kit is programmed with the Water Tolerance configuration by default. See 

 for more information.

The kit includes PSoC 5LP, an ARM-based PSoC that functions as a USB-I

2

C bridge between the

CY8CMBR3116 controller and the PC host (see 

). The CY8CMBR3116 controller commu-

nicates with PSoC 5LP using an I

2

C interface, and the PSoC 5LP transfers the data over USB to the

PC and EZ-Click 2.0 customizer tool.

Cypress provides two USB-I

2

C software utilities: EZ-Click 2.0 and Bridge Control Panel (BCP). The

CY3280-MBR3 EVK uses the EZ-Click 2.0 customizer tool for register configuration. BCP is the soft-
ware provided by Cypress that allows you to communicate over I

2

C, SPI, or RX8 using your PC and

USB. This application currently supports CY3240, MiniProg3, FirstTouch, FirstTouchRF, TrueTouch-
Bridge, DVKProg1, and KitProg bridges. See 

 for

more details on using the BCP.

You should install the EZ-Click 2.0 customizer tool on the PC to evaluate the kit features. This soft-
ware is part of the kit installer, but it can also be downloaded from 

You can use EZ-Click 2.0 to configure the CapSense controllers using I

2

C communication

over the USB-I

2

C bridge. You can also use it to monitor raw count, baseline, SNR, and other

CapSense sensor-related information directly.
