CM7000 20 s Getting Started
Programming Setup
Dynamic C, Z-World’s C-language development system, is used to develop
applications for the CM7000. As a program compiles, Dynamic C down-
loads it directly to the CM7000’s memory via one of the PC COM ports.
Serial communication is normally at 19,200 bps, and can be as high as
57,600 bps. The CM7000 remains connected to the PC in most instances
while a program is undergoing development. The mechanics of connecting
a CM7000 and a PC vary depending on the CM7000 version and the
programming strategy.
The programming strategy for a CM7100 depends on the hardware setup.
Only one programming method is available for the CM7200 regardless of
whether the Developer’s Kit or in-target development is used.
CM7100
Four methods are available to program the CM7100.
1. Using the Prototyping Board. This method is recommended for pro-
gramming the CM7110 supplied in the Evaluation Kit. This CM7110 has
a special EPROM that contains the BIOS and sample programs.
Method 1 may also be used to program other CM7100s. Since an
EPROM is not normally included with CM7100s, except for the
CM7110 in the Evaluation Kit, which comes with a special EPROM, a
custom EPROM with the contents of the Dynamic C
2903.BIN
file
must first be burned according to the details in the section “Program-
ming EPROMs” in Chapter 3, “System Development.”
2. Using the Development Board. The Development Board is included in
the Developer’s Kit with full Dynamic C, and is also sold separately.
3. Using the Development Board with full Dynamic C, and with the
CM7100 embedded in your target system.
4. Directly in your system without a Development Board. This method
requires some hardware setup and minor modifications to the Dynamic C
EPROM code.
Methods 1 and 2 are normally used for evaluation or experimentation.
Method 3 requires some hardware setup, and ultimately must be used to
program a working system. Method 4 can be the fastest and most power-
ful.
Once program development has been completed, recompile the program
for EPROM. An EPROM is burned in a separate operation and is then
installed in the EPROM socket on the CM7100.
