Assembler
The macro assembler enables the assembly code for seamless
merging with C code. The link libraries automatically use abso-
lute addressing or are compiled in relative mode and linked with
other software modules to get absolute addressing.

PSoC Designer Software Subsystems
C Language Compiler
C language compiler supports the PSoC family of devices. It
quickly enables you to create complete C programs for the
PSoC family devices.
The embedded optimizing C compiler provides all the features
of C language tailored to the PSoC architecture. It comes com-
plete with embedded libraries providing port and bus opera-
tions, standard keypad and display support, and extended math
functionality.
Debugger
The PSoC Designer Debugger subsystem provides hardware
in-circuit emulation, enabling the designer to test the program in
a physical system while providing an internal view of the PSoC
device. Debugger commands enable the designer to read the
program, read and write data memory, read and write IO regis-
ters, read and write CPU registers, set and clear breakpoints,
and provide program run, halt, and step control. The debugger
also enables the designer to create a trace buffer of registers
and memory locations of interest.
Device Editor
The device editor subsystem enables the user to select different
on board 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 reconfig-
uration enables changing configurations at run time.
PSoC Designer sets up power on initialization tables for
selected PSoC block configurations and creates source code
for an application 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 program-
ming in conjunction with the device datasheet. Once the frame-
work is generated, the user adds application specific code to
flesh out the framework. It is also possible to change the
selected components and regenerate the framework.
Application Editor
Application Editor edits C language and Assembly language
source code. It also assembles, compiles, links, and builds.
Online Help System
The online help system displays online and 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 to get started.
Hardware Tools
In-Circuit Emulator
A low cost, high functionality ICE (In-Circuit Emulator) is avail-
able 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.
