Normally you order an evaluation kit to check out whether a particular microcontroller seems appropriate for a design you have in mind; if everything seems OK, you then order a more costly development kit to prototype your design. Cypress’ CY3267 PowerPSoC Lighting Evaluation Kit manages to cross that line, enabling a quick out-of-the-box evaluation within a few minutes but including a full suite of tools, circuits, and programmable components to enable developing some sophisticated lighting control systems.
The CY3267 PowerPSoC kit includes a main board built around a CY8CLED04D PowerPSoC MCU in a floating load buck topology. The PSoC core drives four 1A internal MOSFETs that power a 10W 4-channel RGBA LED mounted on a separate daughter card sitting atop a large heatsink. A power supply, USB cable, LED diffuser, an assortment of jumpers, and a MiniProg programming connector complete the kit.
Within five minutes of opening the package I was able to connect the daughter card to the main board; connect the main board to my computer; power up both boards; and cycle through the different colors in the LED array using the two Capsense buttons. Five minutes later I had installed the Intelligent Lighting Control application included on the kit CD and could experiment with basic lighting control.
The Intelligent Lighting Control application (Figure 1) works with the default firmware to demonstrate 4-channel color mixing. From the CIE Color Selection tab you can click on any point on the color gamut and watch the LED array output that color. You can set the intensity by moving the Requested Luminous Flex slider. You can also set the white intensity by moving the Color Temperature Control slider (up to 4000K).
Clicking on the Direct LED Control tab you can move each of the four sliders to select the intensity of the red, green, blue, and amber LEDs. More…
