  • Page 5: Safety Information

    Safety Information Regulatory Compliance ® The CY8CKIT-040 PSoC 4000 Pioneer Kit is intended for use as a development platform for hardware or software in a laboratory environment. The board is an open system design, which does not include a shielded enclosure. For this reason, the board may cause interference to other electrical or electronic devices in close proximity.
  • Page 6 General Safety Instructions ESD Protection ESD can damage boards and associated components. Cypress recommends that the user perform procedures only at an ESD workstation. If an ESD workstation is not available, use appropriate ESD protection by wearing an antistatic wrist strap attached to the chassis ground (any unpainted metal surface) on the board when handling parts.

  • Page 94 Code Examples Figure 5-48 through Figure 5-51 explain the process of generating the intensity levels for the RGB LEDs. The color palette and the saturation slider are both part of the Trackpad area. The following steps summarize the flow. 1. The Trackpad coordinates are obtained as shown in the mapping in Figure 5-48.
  • Page 95 Code Examples 2. Intensity levels of the RGB colors, before applying saturation, are calculated as shown in Figure 5-50. Along the X-Pos, the color palette is divided into six windows. In each window, one color is at maximum brightness, one is at minimum brightness, and one moves from maximum to minimum or vice versa.
  • Page 96 Code Examples 3. After the primary color intensities (from the color palette) are derived from step 2, either the brightness level or the saturation level selected by the slider is applied. The selection between brightness and saturation is done using DO_SATURATION macro defined in main.h. a.

    Appendix Use of Zero-ohm Resistors and No Load Unit Resistor Usage Power supply Solder zero-ohm resistors to access voltage from VBUS (USB). Unsolder the resistors to communicate with an external PSoC C connection between PSoC 5LP R24 and R25 using the PSoC 5LP. Removing these will disable the PSoC 4 I and PSoC 4 communication with the PSoC 5LP device.

  • Page 172: Migrating Projects Across Different Pioneer Series Kits

    Appendix Migrating Projects Across Different Pioneer Series Kits All Cypress Pioneer series kits are Arduino Uno compatible and have some common onboard peripherals such as RGB LED, CapSense, and user switch. However, the pin mapping in each of the boards is different due to differences in pin functions of the PSoC device used. This guide lists the pin maps of the Pioneer series kits to allow for easy migration of projects across different kits.
