Hi all Wisp'ers... I'm happy no announce that my native Wisp port to Windows (port done on W2K), is now running. The major problems (apart from the HD crash :-) ) was that I'm a non-C-expert, and I was mixing up UCHAR with PUCHAR and when to use and when *not* to use the "&" character in parameter passing to functions... Oh well... Anyway, I have been testing with a 18F1320 which runs just fine. Tested with both my old home built Wisp and an "original" ready built Wisp from Wouter I got today. Tested using a standard COM port and using USB-RS232 converter. I've made an agreement with Rob Hamerling, that I'll host the Windows port for the time beeing on my web site, I'll put it up tomorrow, I'll let you know. I will provide the EXE and a full source kit for those interested. I have just some minor tidying up of the code to do. So, now it's a single 130Kb EXE and a 14Kb CFG (with the PIC part specifics), instead of the 40Mb Python install with close to 3000 files :-) :-) And (on my system) it runs in about half the time. Best Regards Jan-Erik. PS. Since someone asked off-list... No, there is *no* GUI. At the moment... :-) Example of flashing one of Wouters example programs for the Dwarfs (DN003.HEX): C:\>xwisp2 port 3 go dn003 XWisp2 version 1.3.03 (Mar 22 2004, LCC) File DN003.Hex loaded and Intel Hex format conforming Total of program and data memory: 110 bytes Programmer Wisp628, firmware version 1.09 Detected target: 18F1320 rev 02 ('07C2') Target erased Transferring image to 18F1320 via Wisp628 Transferring program OK!
