PLEASE NOTE: The GSI-2 Controller has been discontinued. If your project calls for a similar controller, please contact Gunn Systems for more information.
If the standard GSI-2 Hardware or Simple-Rulez® Software does not meet your requirements, Gunn Systems offers both in-house customization and GSI-2 Development Kits for independent development.
The standard GSI-2 (which includes Simple-Rulez) can be used "as is" in a wide variety of projects. However, some GSI-2 customers may need additional input or output capabilities, or perhaps specialized software calculations or interfacing. To accomplish this, the GSI-2 platform was built for expansion from the start.
Gunn Systems is happy to quote any hardware or software changes needed for the GSI-2 to meet specific customer requirements.
We also realize that some customers are going to want to do their own development. For this reason, all of the GSI-2 Software and Hardware design files are released as General Public License.
The GSI-2 Development Kits provide all hardware and software tools needed by engineers who need to make changes to the GSI-2 platform for a specific application.
If your software needs are simple, you may be able to use the freely available assemblers for simple software programs. For more detailed programming, or changes to Simple-Rulez (the GSI-2 logic entry and processing environment), we would recommend purchasing the C Compiler (see the Software Development System section).
If you need the change the hardware, you can use Gerber editors for very simple PC board changes; otherwise, the Eagle PC Board software from Eagle is highly recommended (see the Hardware Development System section).
A Software Development System allows the customer to make custom programs with ultimate flexibility.
For programming the GSI-2, you can use a freely available assembler, or a commercial C compiler (retail $199). Either development system will require the programmer utility.
The GSI-2 Simple-Rulez software was developed with the C compiler, and we recommend buying the C compiler for most needs. The assembler is good for simple needs or where speed needs to be maximized.
Freely available development software for the 68HC08 that works well with the GSI-2:
For modifying the GSI-2 hardware (PC board), there are two options. For simple changes, a freely available Gerber file editor is available. For more complicated hardware changes, the Eagle PCB program can be purchased. The design files used to develop the GSI-2 Hardware are available and released under GPL.
