More Information
Cypress provides a wealth of data at www.cypress.com to help you to select the right PSoC device for your design, and to help you
to quickly and effectively integrate the device into your design. For a comprehensive list of resources, see the knowledge base article
KBA92181, Resources Available for CapSense® Controllers. Following is an abbreviated list for CapSense devices:
Overview: CapSense Portfolio, CapSense Roadmap.
Product Selectors: CapSense, CapSense Plus, CapSense
Express, PSoC3 with CapSense, PSoC5 with CapSense,
PSoC4. In addition, PSoC Designer offers a device selection
tool at the time of creating a new project.
Application Notes: Cypress offers CapSense application notes
covering a broad range of topics, from basic to advanced level.
Recommended application notes for getting started with
CapSense are:
AN64846 – Getting Started With CapSense.
CY8C20x34 CapSense® Design Guide.
AN2397 – CapSense® Data Viewing Tools.
Technical Reference Manual (TRM):
PSoC® CY8C20x24, CY8C20x34 Family Technical
Reference Manual.
Development Kits:
CY3280-20x34 Universal CapSense Controller Kit features
a predefined control circuitry and plug-in hardware to make
prototyping and debugging easy. Programming and
I2C-to-USB Bridge hardware are included for tuning and data
acquisition.
CY3280-SLM Linear Slider Module Kit consists of five
CapSense buttons, one linear slider (with ten sensors) and
five LEDs. This module connects to any CY3280 Universal
CapSense Controller Board, including CY3280-20x34 kit.
CY3280-BBM Universal CapSense Prototyping Module Kit
provides access to every signal routed to the 44-pin
connector on the attached controller board including
CY3280-20x34 kit.
Programming
PSoC supports a number of different programming modes
and tools. For more information see the General
Programming page.
PSoC Designer
PSoC Designer is a free Windows-based Integrated Design Environment (IDE). It enables concurrent hardware and firmware design
of systems based on CapSense (see Figure 1). With PSoC Designer, you can:
1. Drag and drop User Modules to build your hardware system
design in the main design workspace
2. Codesign your application firmware with the PSoC hardware,
using the PSoC Designer IDE C compiler
3. Configure User Module
4. Explore the library of user modules
5. Review user module datasheets
