The next step is to write your main program, and any
sub-routines using PSoC Designer’s Application Editor
subsystem. The Application Editor includes a Project Manager
that allows you to open the project source code files (including
all generated code files) from a hierarchal view. The source code
editor provides syntax coloring and advanced edit features for
both C and assembly language. File search capabilities include
simple string searches and recursive “grep-style” patterns. A
single mouse click invokes the Build Manager. It employs a
professional-strength “makefile” system to automatically analyze
all file dependencies and run the compiler and assembler as
necessary. Project-level options control optimization strategies
used by the compiler and linker. Syntax errors are displayed in a
console window. Double clicking the error message takes you
directly to the offending line of source code. When all is correct,
the linker builds a HEX file image suitable for programming.
The last step in the development process takes place inside the
PSoC Designer’s Debugger subsystem. The Debugger
downloads the HEX image to the In-Circuit Emulator (ICE) where
it runs at full speed. Debugger capabilities rival those of systems
costing many times more. In addition to traditional single-step,
run-to-breakpoint and watch-variable features, the Debugger
provides a large trace buffer and allows you define complex
breakpoint events that include monitoring address and data bus
values, memory locations and external signals.
Document Conventions
Acronyms Used
The following table lists the acronyms that are used in this
document.
Units of Measure
A units of measure table is located in the Electrical Specifications
section.
Table 5
on page 10 lists all the abbreviations used to
measure the PSoC devices.
Numeric Naming
Hexadecimal numbers are represented with all letters in
uppercase with an appended lowercase ‘h’ (for example, ‘14h’ or
‘3Ah’). Hexadecimal numbers may also be represented by a ‘0x’
prefix, the C coding convention. Binary numbers have an
appended lowercase ‘b’ (for example, 01010100b’ or
‘01000011b’). Numbers not indicated by an ‘h’ or ‘b’ are decimal.
