Getting Started Additional CY3280-BK1 Universal CapSense Controller CD Content ■ ■ ■ Example projects for PSoC Express and PSoC Designer Hardware schematics and gerber files CY3240-I2USB software installer and documentation CapSense Best Practices The Universal CapSense Controller has been created using the best practices for CapSense lay out. To enable universality and development of the kit and its projects, certain design elements have been changed from what is recommended for final products.
2. Use the Board as Factory Programmed The examples in this Quick Start are for the CY3280-20x34 and CY3280-SLM Linear Slider Module boards only. The CY3280-20x34 board is preprogrammed with demonstration firmware. When powered by a PSoC MiniProg, a CY3240-I2USB Bridge, or an optional external power supply, the LEDs light up when a finger touches one of the buttons or the slider. These instructions assume your board has not been reprogrammed from the factory settings.
Use the Board as Factory Programmed 2.3 From the Port menu, select MiniProg1/. 2.4 Click Toggle Device Power green. . The D1 LED on the CY3280-20x34 board lights Test the Board 2.5 Touch the slider on the board with your finger. An LED will light up representing where your finger is on the slider. The LED state changes as you move your finger across the slider 2.6 Touch one or more buttons with your finger. The LEDs light up corresponding to the buttons being pressed.
3. Create a PSoC Express CapSense Project This project walks you through the steps of creating a PSoC Express project from scratch. At the end of the project, you will be able to touch a button on the board and see the corresponding LED light up. Start a New Project 3.1 Open PSoC Express. 3.2 Select File New Project. 3.3 Name the project MyExpressProject. 3.4 If needed, click Browse to save the project in a different location. 3.5 Click OK. Add the First CSA Button Driver to Your Design 3.
Create a PSoC Express CapSense Project 3.10 Click OK to accept the default settings. Another Add Input Driver window will open automatically. 3.11 Name this driver CapSenseProperties. 3.12 In the Properties pane, set ExternalCap to Enabled. 3.13 Click OK. Add a Second CSA Button Driver to Your Design 3.14 Repeat Step 3.8 to add a second CSA Button to your design. 3.15 Name the driver Button2. 3.16 Click OK. Add the First LED Value Driver to Your Design 3.
Create a PSoC Express CapSense Project Define the LED Transfer Function 3.25 You now have five drivers on your design desktop: Button1, Button2, LED1, LED2, and CapSenseProperties. Right-click the LED1 driver and select Transfer Function. Note: If your driver icons are stacked on top of each other, simply use your mouse to click and drag each driver to a new location until all five drivers are clearly visible.
Create a PSoC Express CapSense Project Build Your Project 3.32 Select Build Generate/Build ‘MyExpressProject’ Project 3.33 In the PSoC Device Configuration Selection window, select the CY8C20434, 32-Pin QFN part in the Available Device Configurations pane. Note: The CY3280-20x34 Universal CapSense Controller includes a special on-chip debugger (OCD) part, CY8C20000, which is a 48-pin part that is not normally used for production.
Create a PSoC Express CapSense Project 3.38 Assign the rest of the drivers according to the following table: 3RUWB B 3RUWB B 3RUWB B 3 > @ 3 > @ 3 > @ 3RUWB B P2[7] 9'' P2[5] LED2 3RUWB B LED1 3 > @ P0[3] &DS6HQVH3URSHUWLHVB CapSenseProperties_ExternalCap (previously assigned in Step 3.
Create a PSoC Express CapSense Project 3.43 From the Port menu, select MiniProg1/. 3.44 Click Program . “Programming Succeeded...” appears in the Actions pane when programming is complete. Test the Board 3.45 Click Toggle Device Power . 3.46 Touch buttons P1[6] and P1[3] on the board with your finger. The corresponding LED lights up. 3.47 When you are done experimenting, click Toggle Device Power PSoC Programmer. , and close 3.
4. Tune a PSoC Express CapSense Project Note: A CY3240-I2USB Bridge is needed for CapSense tuning. If you do not have a CY3240-I2USB Bridge board, purchase one online by going to http://www.cypress.com/design/DK10063, and clicking Buy Online. The goal of tuning a capacitive sensing application is to adjust the sensitivity of the buttons or slider so that they accurately detect finger presses.
Tune a PSoC Express CapSense Project Assign Drivers to Pins 4.9 In the User Pin Assignment window, click Unassign All Pins. All drivers move to the Unassigned Drivers list. 4.10 To assign drivers to pins, drag and drop drivers from the Unassigned Drivers list onto a pin. Assign the CapSenseProperties_ExternalCap driver to port P0[3]. Assign the rest of the drivers according to the following table. Button1_CSA P1[6] Button2_CSA P1[3] CapSenseProperties_ExternalCap (previously assigned in Step 4.
Tune a PSoC Express CapSense Project 4.22 Touch the button with your finger. The button is now less sensitive. When you're finished experimenting, close the CSA Button Tuner window and then click Stop. Monitoring a design consumes a lot of processor cycles on your PC. Congratulations! You have successfully completed this example.To experiment with additional Universal CapSense designs, go to the \Firmware folder on the kit CD.

5. Create a PSoC Designer CapSense Project This project is a brief introduction to PSoC Designer. It is recommended that you complete the PSoC Designer training offered by Cypress. At the end of the project, you will be able to touch button P2[3] on the CY3280-SLM board and see the corresponding LED light up. A C compiler license is required to build PSoC Designer C language projects. Section 2.1 of the C Language Compiler Users Guide.pdf found in Help Documentation explains how to enter the license.
