Getting Started

For in-depth information, along with detailed programming

details, see the PSoC

Technical Reference Manual.

For up-to-date ordering, packaging, and electrical specification

information, see the latest PSoC device datasheets on the web.

Application Notes

Cypress application notes are an excellent introduction to the

wide variety of possible PSoC designs.

Development Kits

PSoC Development Kits are available online from and through a

growing number of regional and global distributors, which

include Arrow, Avnet, Digi-Key, Farnell, Future Electronics, and

Newark.

Training

Free PSoC technical training (on demand, webinars, and

workshops), which is available online via www.cypress.com,

covers a wide variety of topics and skill levels to assist you in

your designs.

CYPros Consultants

Certified PSoC consultants offer everything from technical

assistance to completed PSoC designs. To contact or become a

PSoC consultant go to the CYPros Consultants web site.

Solutions Library

Visit our growing library of solution focused designs. Here you

can find various application designs that include firmware and

hardware design files that enable you to complete your designs

quickly.

Technical Support

Technical support – including a searchable Knowledge Base

articles and technical forums – is also available online. If you

cannot find an answer to your question, call our Technical

Support hotline at 1-800-541-4736.

Development Tools

PSoC Designer™ is the revolutionary integrated design

environment (IDE) that you can use to customize PSoC to meet

your specific application requirements. PSoC Designer software

accelerates system design and time to market. Develop your

applications using a library of precharacterized analog and digital

peripherals (called user modules) in a drag-and-drop design

environment. Then, customize your design by leveraging the

dynamically generated application programming interface (API)

libraries of code. Finally, debug and test your designs with the

integrated debug environment, including in-circuit emulation and

standard software debug features. PSoC Designer includes:

■ Application editor graphical user interface (GUI) for device and

user module configuration and dynamic reconfiguration

■ Extensive user module catalog

■ Integrated source-code editor (C and assembly)

■ Free C compiler with no size restrictions or time limits

■ Built-in debugger

■ In-circuit emulation

■ Built-in support for communication interfaces:

❐ Hardware and software I

C slaves and masters

❐ Full-speed USB 2.0

❐ Up to four full-duplex universal asynchronous

receiver/transmitters (UARTs), SPI master and slave, and

wireless

PSoC Designer supports the entire library of PSoC 1 devices and

runs on Windows XP, Windows Vista, and Windows 7.

PSoC Designer Software Subsystems

Design Entry

In the chip-level view, choose a base device to work with. Then

select different onboard analog and digital components that use

the PSoC blocks, which are called user modules. Examples of

user modules are ADCs, DACs, amplifiers, and filters. Configure

the user modules for your chosen application and connect them

to each other and to the proper pins. Then generate your project.

This prepopulates your project with APIs and libraries that you

can use to program your application.

The tool also supports easy development of multiple

configurations and dynamic reconfiguration. Dynamic

reconfiguration makes it possible to change configurations at run

time. In essence, this allows you to use more than 100 percent

of PSoC's resources for an application.

Code Generation Tools

The code generation tools work seamlessly within the

PSoC Designer interface and have been tested with a full range

of debugging tools. You can develop your design in C, assembly,

or a combination of the two.

Assemblers. The assemblers allow you to merge assembly

code seamlessly with C code. Link libraries automatically use

absolute addressing or are compiled in relative mode, and are

linked with other software modules to get absolute addressing.

C Language Compilers. C language compilers are available

that support the PSoC family of devices. The products allow you

to create complete C programs for the PSoC family devices. The

optimizing C compilers provide all of the features of C, tailored

to the PSoC architecture. They come complete with embedded

libraries providing port and bus operations, standard keypad and

display support, and extended math functionality.

Debugger

PSoC Designer has a debug environment that provides

hardware in-circuit emulation, allowing you to test the program in

a physical system while providing an internal view of the PSoC

device. Debugger commands allow you to read and program and

read and write data memory, and read and write I/O registers.

You can read and write CPU registers, set and clear breakpoints,

and provide program run, halt, and step control. The debugger

also allows you to create a trace buffer of registers and memory

locations of interest.

Online Help System
