Designing with PSoC Designer
The development process for the PSoC
®
device differs from that
of a traditional fixed function microprocessor. The configurable
analog and digital hardware blocks give the PSoC architecture a
unique flexibility that pays dividends in managing specification
change during development and by lowering inventory costs.
These configurable resources, called PSoC Blocks, have the
ability to implement a wide variety of user-selectable functions.
The PSoC development process is summarized in four steps:
1. Select User Modules.
2. Configure user modules.
3. Organize and connect.
4. Generate, verify, and debug.
Select User Modules
PSoC Designer provides a library of prebuilt, pretested hardware
peripheral components called “user modules.” User modules
make selecting and implementing peripheral devices, both
analog and digital, simple.
Configure User Modules
Each user module that you select establishes the basic register
settings that implement the selected function. They also provide
parameters and properties that allow you to tailor their precise
configuration to your particular application. For example, a pulse
width modulator (PWM) User Module configures one or more
digital PSoC blocks, one for each 8 bits of resolution. The user
module parameters permit you to establish the pulse width and
duty cycle. Configure the parameters and properties to
correspond to your chosen application. Enter values directly or
by selecting values from drop-down menus. All the user modules
are documented in datasheets that may be viewed directly in
PSoC Designer or on the Cypress website. These user module
datasheets explain the internal operation of the user module and
provide performance specifications. Each datasheet describes
the use of each user module parameter, and other information
you may need to successfully implement your design.
