Easy-to-write programs
CAMBASIC is termed as the “no hassle” embedded language. It only
takes four simple steps to write the program and much less time than C.
1. At the C:> prompt, type CAMBASIC.
2. Write your program. CAMBASIC comes with several programming
examples.
3. Debug your program.
4. Type SAVE name.
Keyboard mode to debug hardware
The immediate keyboard mode used to examine system components and
wiring hardware can quicken system debugging. The BIT command can
be used to turn on and off motors, relays, etc. Even if C or another
language is used for the applications program, CAMBASIC is always in
flash and remains a fast and useful tool to validate correct system
operation.
Built-in help and error messages
CAMBASIC has built-in help messages for pin-pointing problems. For
example, when an error occurs in a user program, the syntax of the
command that caused the error is displayed.
