Introduction

1.1.2 CY3217-MiniProg1The 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 USB A to Mini-B cable. During prototyping, theMiniProg can be used as an in-system serial programmer (ISSP) to program PSoC devices on yourPCB. 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 astandalone program.

1.1.3 CY3240-I2USB Bridge BoardThe 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 I2USBBridge can be connected through the ISSP pins on the controller board.

1.1.4 CY3280 Universal CapSense Module BoardThe CY3280 Universal CapSense Module board is available for purchase separately or as part ofthe combination kits. The CY3280-24x94 UCC can be connected to CY3280-SLM, CY3280-SRM,CY3280-BMM, and CY3280-BSM CapSense boards.

1.2 PSoC DesignerPSoC Designer<version> is the integrated development environment (IDE) used to customize yourPSoC application. The latest PSoC Designer has many new features, bug fixes, and support for newPSoC devices. More information about PSoC Designer is available in the PSoC Designer IDE Guideat <Installed_directory>\Cypress\PSoC Designer\<version>\Documentation.

1.3 PSoC ProgrammerPSoC Programmer offers you a simple GUI that connects to programming hardware to program andconfigure PSoC devices.

1.4 Bridge Control PanelThe 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 toconfigure I2C devices and to acquire and process data received from I2C slave devices. The BCPhelps to optimize, debug, and tune the target devices.

4.2.1 PSoC CY8C24094-24LTXIThe PSoC CY8C24094 is initially factory programmed as a CapSense controller with the control cir-cuitry to work with the CY3280-24x94 UCC kit. The PSoC CY8C24094 along with CSD technologydemonstrates the use of CapSense buttons and linear sliders. The module board connected to theCY3280-24x94 Universal CapSense Controller has sensors and LEDs.

The CapSense module board is connected to PSoC through Port P2. The list of pins connected todifferent ports is shown in Table 4-1.

PSoC CY8C24094 is programmed through ISSP using a MiniProg and the data acquisition and out-put checking is done using I2USB Bridge.

4.2.2 Power Supply SystemThe power supply system on this board is versatile; it takes input supply from the following sources:■ 12 V DC supply using connector J5■ 9 V battery connector using connectors BH1 and BH2■ USB power (5 V) from communications section using connector J6■ Power from MiniProg and I2USB Bridge connected at J3■ Power from ICE Cube connected at P1

The board power domain is split into:■ Vin rail: This is the rail where the input of the on-board regulators is connected. This domain is

powered by the power sources (12 V DC supply and 9 V battery terminal) through protection diodes.

■ 5 V rail: This is the output of the 5 V regulator IC U5 and also from the devices such as MiniProg or I2USB Bridge. The rail is a fixed 5 V output regardless of any jumper settings. The voltage in this rail can be less than 5 V only when the board is powered by the USB power.

5. Code Examples

All code examples are available in the Firmware folder of the kit CD or at the following location:<Install_directory>\Cypress\CY3280-24x94\<version>\Firmware\

5.1 My First Code Example

5.1.1 Project DescriptionThis project demonstrates the use of the CapSense buttons and linear slider on the CY3280-SLMboard using CSD technology and CY8C24x94. The EzI2C user module is used to transferCapSense parameters related to a sensor from the board to the PC for monitoring.

This project scans five CapSense buttons and a 10-segment slider using the CSD user module.There are five LEDs on board, which illuminate when a CapSense button or slider is touched. TheEzI2C user module is used to provide a register-based I2C slave communications protocol. The sta-tus of CapSense sensors (both button and slider) and their parameters are updated in the I2C regis-ter. This register can be accessed by any I2C master, similar to the I2USB Bridge.

The application starts by executing boot.asm. The boot.asm does the hardware initialization andinvokes the 'main' function. The main function initializes the EzI2C Slave user module andCapSense user module. After initialization, the main function enters a loop, which does the following:■ Scans all sensors■ Reads the sensor ID sent by the I2C master■ Stores CapSense data in the I2C registers■ Updates the LED status for the On/Off sensors

The following user modules are used in this project:■ CSD: The CSD provides capacitance sensing using the switched capacitor technique with a

sigma-delta modulator to convert the sensed switching capacitor current to digital code.■ EzI2Cs: The EzI2Cs user module implements an I2C register-based slave device.This user mod-

ule does not require any digital or analog PSoC blocks. It is used to transfer all CapSense param-eters related to a sensor to the PC for monitoring.

5.2.1 Project DescriptionThis project demonstrates the use of the CapSense buttons and linear slider on the CY3280-SLMboard using CSD technology and CY8C24x94A. The EzI2Cs user module is used to transferCapSense parameters related to a sensor to the PC for monitoring. This project is implemented inthe chip level design in PSoC Designer 5.1.

This project scans five CapSense buttons and a 10-segment slider using the CSD user module.There are five LEDs on board, which illuminate when a CapSense button or slider is touched. TheEzI2Cs user module is used to provide a register-based I2C slave communications protocol. Thestatus of CapSense sensors (both button and slider) and their parameters are updated in the I2Cregister, which can be accessed by any I2C master, similar to the I2USB Bridge.

The application starts by executing boot.asm. The boot.asm does the hardware initialization andinvokes the 'main' function. The main function initializes the EzI2Cs Slave user module andCapSense user module. After initialization, the main function enters into a loop, which does the fol-lowing:■ Scans all sensors■ Reads the sensor ID sent by the I2C master■ Stores CapSense data in the I2C registers■ Updates the LED status for the On/Off sensors


sigma delta modulator to convert the sensed switching capacitor current to digital code.■ EzI2Cs: The EzI2Cs user module implements an I2C register based slave device.This user mod-

1. Touch one or more buttons; the associated LEDs light up.2. Touch the linear slider; the associated LEDs light up.3. Touch the linear slider and buttons simultaneously. The associated LEDs light up corresponding

to the buttons and the sliders being pressed.4. In the first command line, change the sensor ID for which parameter monitoring is required and

click Send to write the sensor ID to the Universal CapSense Controller board. See Figure 5-39 (w 05 0 1 p, where 05 is the I2C slave address, 0 is the address pointer, and 1 is the sensor ID). See Table 5-2 for a complete list of sensor IDs.

5. Click on the second command line and then click Repeat to read I2C data received from the Uni-versal CapSense Controller board.

6. Switch to the Chart tab to view the respective wave forms of CapSense parameters; see Figure 5-40.

Note The character 'w' in Figure 5-2 defines the start of "write data" command. The character 'p'generates stop condition on the I2C bus and character 'r' defines the start of "read data" command.
