Using CapSense® Buttons for LED Control on the CY3267 PowerPSoC® Evaluation Kit

Question: How to use the CapSense button for LED control on the CY3267 PowerPSoC® Evaluation Kit?

 

Answer:

 

The CY3267 PowerPSoC® evaluation board has two devices – CY8CLED04D01 (PowerPSoC) and CY8C24894 (CapSense® enabled PSoC® 1). The CapSense buttons on the board are connected to the CY8C24894 and the LEDs on the daughter card are controlled by the CY8CLED04D01. The communication between these two chips is through I2C.

The attached example projects aim to configure the CapSense buttons to control the LEDs. I2C communication is used between the two devices to communicate the status of the CapSense buttons. For a detailed explanation of the projects and the instructions to use the same, refer the attached document.
