Introduction
1.1.2 CY3217-MiniProg1
The PSoC MiniProg 1 gives you the ability to program PSoC parts quickly and easily. It is small,
compact, and connects to your PC using the provided retractable USB cable. During prototyping, the
MiniProg can be used as an in-system serial programmer (ISSP) to program PSoC devices on your
PCB. When the MiniProg is connected, you can use the PSoC Programmer software to program.
PSoC Programmer is a free software, which can either be launched from PSoC Designer or run as a
standalone program.
1.1.3 CY3240-I2USB Bridge Board
The I2USB Bridge allows testing, tuning, and debugging hardware and software of a PSoC applica-
tion by bridging the USB port to I2C. Populated with the CY8C24894 PSoC device, the I2USB
Bridge can be connected through the ISSP pins on the controller board.
1.1.4 CY3280 Universal CapSense Module Board
The CY3280 Universal CapSense Module board is available for purchase separately or as part of
the combination kits. The CY3280-24x94 UCC can be connected to CY3280-SLM, CY3280-SRM,
CY3280-BMM, and CY3280-BSM CapSense boards.
1.2 PSoC Designer
PSoC Designer<version> is the integrated development environment (IDE) used to customize your
PSoC application. The latest PSoC Designer has many new features, bug fixes, and support for new
PSoC devices. More information about PSoC Designer is available in the PSoC Designer IDE Guide
at <Installed_directory>\Cypress\PSoC Designer\<version>\Documentation.
1.3 PSoC Programmer
PSoC Programmer 3.12 offers you a simple GUI that connects to programming hardware to program
and configure PSoC devices.
1.4 Bridge Control Panel
The Bridge Control Panel (BCP) GUI is used with CY3240-I2USB Bridge Board to enable communi-
cation with I2C slave devices; here, it is used with CY3280-24x94 UCC. This software is used to
configure I2C devices and to acquire and process data received from I2C slave devices. The BCP
helps to optimize, debug, and tune the target devices.

3. Kit Operation
3.1 Introduction
The CY3280-24x94 UCC connects to any CY3280 Universal CapSense Module board. This kit
requires PSoC Designer for development, PSoC Programmer for programming, and Bridge Control
Panel to test and tune the CapSense parameters.
3.2 Hardware Requirement
■CY3280-24x94 UCC board (PSoC Device ID: CY8C24094-24LFXI)
■CY3280-SLM (linear slider module) board
■MiniProg1
■CY3240-I2USB Bridge Board
■Retractable USB Cable (A to mini-B)
3.3 CapSense Module Board Connection
The CapSense Module Board can be connected to the controller through Port P2 of the controller
and J1 of the CY3280-SLM Universal CapSense linear slider module.
Figure 3-1. Connecting CapSense Module Board to Universal CapSense Controller
On the CY3280-24x94 UCC board, place shunts on pins 1 to 2 of J4 (XRES select). On the CY3280-
SLM Universal CapSense Linear Slider Module, place a shunt on pins 2 and 3 of J2.

Kit Operation
3.4 Programming Device
The CY3280-24x94 UCC is programmed using a MiniProg1 provided with the kit.
Figure 3-2. MiniProg 1 Connected to Controller
1. Connect your computer to the CY3280-24x94 ISSP connector (J3) using the PSoC MiniProg 1
and a USB cable (A to Mini B). Use PSoC Programmer for programming.
2. Connect pin 2 of J1 with a jumper to pin 3 to allow power to be supplied by the MiniProg1.
3. LED D1 on the CY3280-24x94 UCC is ON when the board is powered from a 12 V DC supply,
USB, 9 V battery, PSoC MiniProg, I2USB Bridge, or VADJ. LED D2 lights up once the board is
powered by any of the power sources (12 V DC supply, USB, 9 V battery, PSoC MiniProg,
I2USBBridge, ICE Cube, or VADJ).
4. Program the hex file on to the CY3280-24x94 UCC board using MiniProg 1. While programming
is in progress, the Target Power LED on the MiniProg 1 is ON (see Figure 3-2).
5. When Programming Succeeded appears in the Actions pane, detach the MiniProg 1 and con-
nect an I2USB Bridge to ISSP connector.
