PSoC Designer Software Subsystems
Device Editor
The Device Editor subsystem allows the user to select different
onboard analog and digital components called user modules
using the PSoC blocks. Examples of user modules are ADCs,
DACs, amplifiers, and filters.
The device editor also supports easy development of multiple
configurations and dynamic reconfiguration. Dynamic configu-
ration allows changing configurations at run time.
PSoC Designer sets up power-on initialization tables for selected
PSoC block configurations and creates source code for an appli-
cation framework. The framework contains software to operate
the selected components. If the project uses more than one
operating configuration, then it contains routines to switch
between different sets of PSoC block configurations at run time.
PSoC Designer prints out a configuration sheet for a given
project configuration for use during application programming in
conjunction with the device data sheet. After the framework is
generated, the user can add application specific code to flesh out
the framework. It is also possible to change the selected compo-
nents and regenerate the framework.
Design Browser
The Design Browser allows users to select and import precon-
figured designs into the project. Users can easily browse a
catalog of preconfigured designs to facilitate time-to-design.
Examples provided in the tools include a 300-baud modem, LIN
Bus master and slave, fan controller, and magnetic card reader.
Application Editor
The Application Editor edits the C language and assembly
language source code. It also assembles, compiles, links, and
builds.
Assembler. The macro assembler allows the assembly code to
be merged seamlessly with C code. The link libraries automati-
cally use absolute addressing or can be compiled in relative
mode, and linked with other software modules to get absolute
addressing.
C Language Compiler. A C language compiler is available that
supports the PSoC family of devices. Even if you have never
worked in the C language before, the product quickly allows you
to create complete C programs for the PSoC family devices.
The embedded, optimizing C compiler provides all the features
of C tailored to the PSoC architecture. It comes complete with
embedded libraries providing port and bus operations, standard
keypad and display support, and extended math functionality.
Debugger
The PSoC Designer Debugger subsystem provides hardware
in-circuit emulation, allowing the designer to test the program in
a physical system while providing an internal view of the PSoC
device. Debugger commands allow the designer to read and
program and read and write data memory, read and write IO
registers, read and write CPU registers, set and clear break-
points, and provide program run, halt, and step control. The
debugger also allows the designer to create a trace buffer of
registers and memory locations of interest.
Online Help System
The online help system displays online, context-sensitive help
for the user. Designed for procedural and quick reference, each
functional subsystem has its own context-sensitive help. This
system also provides tutorials and links to FAQs and an Online
Support Forum to aid the designer in getting started.
Hardware Tools
In-Circuit Emulator
A low cost, high functionality ICE (In-Circuit Emulator) is
available for development support. This hardware has the
capability to program single devices.
The emulator consists of a base unit that connects to the PC by
way of a USB port. The base unit is universal and operates with
all PSoC devices. Emulation pods for each device family are
available separately. The emulation pod takes the place of the
PSoC device in the target board and performs full speed (24
MHz) operation.
TrueTouch Touchscreen Tuner
The TrueTouch tuner is a Microsoft® Windows based graphical
user interface allowing developers to set critical parameters and
observe changes to the touchscreen application in real time.
Optimal configuration from the tuner are immediately applied to
the TrueTouch user module settings.
