give you the background needed for color mixing and high brightness LEDs which will enable

you to complete and understand color mix designs using Cypress' EZ-Color HB LED Controller.

The module is broken into three sections. The module first describes the composition of color,

tristimulus values, and the CIE 1931 color space. Secondly, the module will describe what LEDs

are and how they work. Finally the module will lead into HB LEDs and basic color mixing.

■EZ-Color 101: Using PSoC Express and Temperature Feedback. The EZ-Color 101 module will

introduce you to the EZ-Color HB LED Controller solution as well as PSoC Express. The mod-

ule contains two labs enabling you to navigate PSoC Express as well as enable you to begin

creating intelligent lighting designs in PSoC Express using binning specifications and tempera-

ture feedback.

6. Review Additional ColorLock EZ-Color Resources

The CY3263-ColorLock EZ-Color evaluation board demonstrates the ability of a PSoC® controller

to use real-time optical feedback to control three primary, high brightness LEDs and create accurate,

mixed-color output. The three LEDs on the CY3263 evaluation board use the primary colors red,

green, and blue, although any three primary color LEDs can be used in a design, depending upon

the application and the desired color gamut.

Right out of the box, CY3263-ColorLock EZ-Color can be used to evaluate and demonstrate EZ-

Color functionality, including color mixing and optical feedback. Part of evaluating ColorLock

requires using a PC GUI to monitor and control ColorLock functionality (see Section Section 4. Use

the Board as Factory Programmed).

The next step is to develop a ColorLock application using this kit as a platform. Use PSoC Express,

Cypress's revolutionary visual embedded design tool, to quickly design powerful lighting applica-

tions. See Section 5. Explore the CY3263 Hands-On Example Projects.

WARNING: HIGH BRIGHTNESS LEDs CAN CAUSE PERMANENT EYE

DAMAGE!

Do not look at the LEDs if they are not covered by the protective enclosure.

The LEDs illuminate at a very high intensity and can cause permanent eye

damage if they are viewed without the protective enclosure.

5. Explore the CY3263 Hands-On Example Projects

The CY3263-ColorLock EZ-Color Evaluation Kit Guide (available on the CD in \documents) con-

tains three PSoC Express example projects. These examples take you step-by-step from creating a

new project and adding drivers and valuators, through programming and tuning the evaluation

board. Discover how designing with PSoC Express is quick, easy, and powerful by experiencing the

step-by-step example projects in the kit guide.

Chapter 3: Tuner Project

This project creates firmware that color mixes three primary high-brightness LEDs to a specific color

and introduces optical feedback into the system using a color sensor. The user can then choose the

Tuner to select other desired colors mapped along the 1931 CIE XYZ Color Space.

Chapter 4: Traffic Light Project

This project creates firmware that color mixes three primary high-brightness LEDs to the three

cycled colors found in a traffic light and introduces optical feedback into the system using a color

sensor. The user can then choose the Tuner to select other desired colors mapped along the 1931

CIE XYZ Color Space.

Chapter 5: Modulated Dimmer Project

This project creates firmware that color mixes three primary high-brightness LEDs to a single color,

modulates the brightness and introduces optical feedback into the system using a color sensor. The

user can then choose the Tuner to select other desired colors mapped along the 1931 CIE XYZ

Color Space.

4. Use the Board as Factory Programmed

The board can be controlled using the Windows ColorLock Monitor application provided on the kit’s

CD. This application can be installed on a personal computer running either the Windows XP or Win-

dows Vista operating system. (Note The application might run on earlier versions of Windows, but it

has not be tested for those versions.) See the CY3263-ColorLock EZ-Color Evaluation Kit Guide for

detailed instructions on the CY3263-Color Monitor application.

When using the board with the ColorLock Monitor application, the board must be attached to the

computer using a USB cable (included). The board can be attached to the computer before or after

the application is started. Once the hardware is attached, the status field located on the bottom edge

of the display on the right-hand side indicates that the hardware is present. This status field is dis-

played as green when the hardware is present and red otherwise.

Note The ColorLock Monitor application is completely separate from the Tuner in PSoC Express

and will not function while PSoC Express is open.

4.8. Click the Green Arrow in the toolbar to run the GUI. You can now see the optical feedback

algorithm in action.

4.9. Select different colors on the CIE color chart and watch the ColorLock kit lock on that color.

4.10. Observe the Current CIE Sensor Coordinates chart in the upper left. This is a plot over time

of the x and y values measured by the color sensor in the system.

4.11. Observe the ColorLock Accuracy chart in the upper right. This is a plot over time of the

delta between the measured x and y values and target x, y displayed beneath the CIE color

chart. Each time a different color is selected you will see a dramatic change in these values,

and as the ColorLock feedback algorithm works, it will pull this delta close to zero (within

some margin of error).

4.12. Observe the PrISM Values chart in the lower right. This is a plot over time of PrISM dimmer

values of the red, green and blue LEDs.

4.13. Adjust the brightness using the Brightness slider to the right of the CIE chart.

4.14. Evaluate ColorLock by exposing the hole in the bottom of the ColorLock case to an external

light source and notice the adjustment of PrISM dimming levels to maintain the target color.
