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: hamhud@yahoogroups.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!

(HiTech Assembler)
loader.zip 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)

HH2Loader_Rel2_1.zip
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.
