PSOC™ Designer

The CY8C20x34 CAPSENSE™ family provides programmable touch sensing via assembly or C language coding in 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™. With PSOC™ Designer, you can:

  1. Drag and drop User Modules to build your hardware system
  2. design in the main design workspace.
  3. Codesign your application firmware with the PSOC™ hardware,
  4. using the PSOC™ Designer IDE C compiler.
  5. Configure User Module.
  6. Explore the library of user modules.
  7. Review user module datasheets.
