This Resource Page presents basic guidance, application notes, documentation and other useful information for homebrewers looking to use the HC908 Daughtercard at its fullest potential. 

TOOLS

• WinIDE Development Environment -- Describes how to download, install and use this free "Integrated Development Environment", a Windows-based editor and assembler for the daughtercard.
   

  The WinIDE development environment (editor, compiler, debugger) is still available for free, but they make it harder and harder to find it these days …. http://www.pemicro.com/products/product_viewDetails.cfm?product_id=147&menu_id=details&CFID=3215646&CFTOKEN=a000491e065adc87-092D184F-1E67-4D2B-C93616E43D63B4A2 … Just click on the PKG08SZ item (second down in right column), then do the simple registration and you’ll be cleared to download the whole package.

• TeraTerm Terminal Program -- Describes how to download, install and configure this free terminal program used for control of the daughtercard.  [For Windows 7, try using the Indigo Terminal Emulator ... works great!]

• CodeWarrior -- Describes how to download, install and use this free 'C' language compiler for the HC908 platform

SOFTWARE

• HCmon -- Debug monitor preloaded on all HC908 Daughtercards allows memory & register inspection/edit, loading of new programs, etc.

• Exerciser -- Simple application used to test and demonstrate connection & control of various hardware peripherals such as LCD, DDS, shaft encoder, etc. 

• VFO -- A daughtercard application that drives a DDS chip to perform as a flexible HF VFO.

• Commander -- A daughtercard application that provides remote control over the RS-232 serial port to the popular FT-817 HF transceiver.

• Template -- The standard 'shell' of a program that can be used as a starting point for custom-developed software programs.

• Blink -- A real simple program that demonstrates the absolute bare-minimal code required to have the daughtercard do something (blink the heartbeat LED).

• Keyer -- A basic iambic keyer

DOCUMENTATION

• Daughtercard Manual -- The most current manual being distributed with the daughtercard. (Caution, big file: 3.4 MB)

• Daughtercard Schematic -- Wiring diagram for all components contained on the daughtercard.

• Test Fixture Schematic -- The Test Fixture is used to program and test all daughtercards prior to shipment. It runs the Exerciser program and contains many hardware elements one can use in making custom projects.

• Daughtercard PCB Trace Diagram -- Shows how are all those those thin traces are routed on the pcb between the 64-pin HC908 controller and the edge connectors.

TECHNICAL SUPPORT

We want your experience with its projects to be enjoyable and as bug-free as possible. To that end, if you are having trouble with your HC908 Daughtercard or with any of its associated project software, please write us and clearly explain your problems. We'll do our best to help get things straightened out. In most cases we can respond within a day or so and thereafter we'll iterate with you until the problem is resolved. The only thing we ask is that you carefully read the information contained on these resource pages to see if your troubles have been previously identified by others and perhaps already solved.

For help with the HC908 Daughtercard, please write to George Heron, N2APB at the address below.
