Code Generation Tools
Document Conventions
PSoC Designer supports multiple third party C compilers and
assemblers. The code generation tools work seamlessly within
the PSoC Designer interface and have been tested with a full
range of debugging tools. The choice is yours.
Units of Measure
A units of measure table is located in the Electrical Specifications
section. Table 5 on page 13 lists all the abbreviations used to
measure the PSoC devices.
Assemblers. The assemblers allow assembly code to merge
seamlessly with C code. Link libraries automatically use absolute
addressing or are compiled in relative mode, and linked with
other software modules to get absolute addressing.
Numeric Naming
Hexidecimal numbers are represented with all letters in
uppercase with an appended lowercase ‘h’ (for example, ‘14h’ or
‘3Ah’). Hexidecimal numbers may also be represented by a ‘0x’
prefix, the C coding convention. Binary numbers have an
appended lowercase ‘b’ (e.g., 01010100b’ or ‘01000011b’).
Numbers not indicated by an ‘h’ or ‘b’ are decimal.
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 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.
Acronyms Used
The following table lists the acronyms that are used in this
document.
Debugger
Acronym
AC
Description
alternating current
The PSoC Designer Debugger subsystem 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 the designer to read and program
and read and write data memory, read and write I/O registers,
read and write CPU registers, set and clear breakpoints, 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.

ICE
A low cost, high functionality In-Circuit Emulator (ICE) is
available for development support. This hardware has the
capability to program single devices.

input/output
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.
