HamHUD II (Revision E) Kit
The HamHUD II Rev-E kit consists of a PCB, an anodized, extruded aluminum case specially-machined for the HamHUD II, an FRAM, a
pre-programmed 18F252 PIC, encoder, switches, hardware and all parts to build a complete
unit. The cable to the "outside world." isn't included, but the mating connector is. That
cable will be up to the end user to build.
Please send bug reports to the hamhud email list: email@example.com
(You must be a member to do so.)
NOTE: ALL 20 MHz FIRMWARE IS NOW OBSOLETE. If your
PIC18F252 HamHUD II still has a 20 MHz crystal, you can get a 10 MHz
one at the HamHUD Webstore, and your HamHUD can run at 40 MHz!

||Schematic, PDF format
|Voltage Troubleshooting Chart
Thanks to Dale Seaburg, Tim Shephard, and Tate Belden. Thi s still applies to the PIC18F version.
||Windows Firmware Loader Software
||Customize or upgrade your HamHUD II.
Loader Extension Hexfile
||Contains the loader.asm and loader.hex for the
18Fversions. There may be
some who wish to program their own PIC with a PIC programmer (such as
theWarp13a). Append the loader.hex file with the firmware hex file, using a text editor.
YOU DO NOT NEED THIS IF YOU HAVE A PRE-PROGRAMMED PIC18F252!
Serial Downloader (Windows)
|Works on PIC18F252 version HH22.7.00 and above.
fram.ini is required by this loader to work, and is included in the firmware zipfile.
NOTE: All PIC18F252 versions require the FM25640 or FM25W256 or FM25256A FRAM.

||2.4.025h and above require the FM25640FRAM.
2.4.025h and above include US/metric units.
|This is firmware that, when loaded into the HamHUD,allowsyou to go from pre-2.4.025k5 to current, FRAM-based versions
|Serial Downloader (DOS EXE)
|Serial Downloader - works on version 2.4.024k5
andabove. If starting from version 2.4.007 through 2.4.012,
apatchmust be applied to the PIC by using the LoaderLoader, above.
