7.1.3 Example System Function Components

The following is a sample of the system function components

available in PSoC Creator for the CY8C54LP family. The exact

amount of hardware resources (UDBs, SC/CT blocks, routing,

RAM, flash) used by a component varies with the features

selected in PSoC Creator for the component.

7.1.4 Designing with PSoC Creator

7.1.4.1

More Than a Typical IDE

A successful design tool allows for the rapid development and

deployment of both simple and complex designs. It reduces or

eliminates any learning curve. It makes the integration of a new

design into the production stream straightforward.

PSoC Creator is that design tool.

PSoC Creator is a full featured Integrated Development

Environment (IDE) for hardware and software design. It is

optimized specifically for PSoC devices and combines a modern,

powerful software development platform with a sophisticated

graphical design tool. This unique combination of tools makes

PSoC Creator the most flexible embedded design platform

available.

Graphical design entry simplifies the task of configuring a

particular part. You can select the required functionality from an

extensive catalog of components and place it in your design. All

components are parameterized and have an editor dialog that

allows you to tailor functionality to your needs.

PSoC Creator automatically configures clocks and routes the I/O

to the selected pins and then generates APIs to give the

application complete control over the hardware. Changing the

PSoC device configuration is as simple as adding a new

component, setting its parameters, and rebuilding the project.

At any stage of development you are free to change the

hardware configuration and even the target processor. To

retarget your application (hardware and software) to new

devices, even from 8- to 32-bit families, just select the new

device and rebuild.

You also have the ability to change the C compiler and evaluate

an alternative. Components are designed for portability and are

validated against all devices, from all families, and against all

supported tool chains. Switching compilers is as easy as editing

the from the project options and rebuilding the application with

no errors from the generated APIs or boot code.

7.1.4.2

Component Catalog

The component catalog is a repository of reusable design

elements that select device functionality and customize your

PSoC device. It is populated with an impressive selection of

content; from simple primitives such as logic gates and device

registers, through the digital timers, counters and PWMs, plus

analog components such as ADC, DACs, and filters, and

communication protocols, such as I2C, USB and CAN. See

“Example Peripherals” section on page 37 for more details about

available peripherals. All content is fully characterized and

carefully documented in datasheets with code examples, AC/DC

specifications, and user code ready APIs.

7.1.4.3

Design Reuse

The symbol editor gives you the ability to develop reusable

components that can significantly reduce future design time. Just

draw a symbol and associate that symbol with your proven

design. PSoC Creator allows for the placement of the new

symbol anywhere in the component catalog along with the

content provided by Cypress. You can then reuse your content

as many times as you want, and in any number of projects,

without ever having to revisit the details of the implementation.

7.1.4.4

Software Development

Anchoring the tool is a modern, highly customizable user

interface. It includes project management and integrated editors

for C and assembler source code, as well the design entry tools.

Project build control leverages compiler technology from top

commercial vendors such as ARM® Limited, Keil™, and

CodeSourcery (GNU). Free versions of Keil C51 and GNU C

Compiler (GCC) for ARM, with no restrictions on code size or end

product distribution, are included with the tool distribution.

Upgrading to more optimizing compilers is a snap with support

for the professional Keil C51 product and ARM RealView™

compiler.

7.1.4.5

Nonintrusive Debugging

With JTAG (4-wire) and SWD (2-wire) debug connectivity

available on all devices, the PSoC Creator debugger offers full

control over the target device with minimum intrusion.

Breakpoints and code execution commands are all readily

available from toolbar buttons and an impressive lineup of

windows—register, locals, watch, call stack, memory and

peripherals—make for an unparalleled level of visibility into the

system.

PSoC Creator contains all the tools necessary to complete a

design, and then to maintain and extend that design for years to

come. All steps of the design flow are carefully integrated and

optimized for ease-of-use and to maximize productivity.
