Hi All, The schematic and some test software for my Scenix programmer are up on my web page: http://www.codepuppies.com/~ben/sens/pic/sx I still have an issue or two to address with the PC software (ie. input file format), which is why the complete package isn't up yet. However, there are two diagnostic executables which will enable you to verify that the programmer is working correctly. As explained on the web page, I'm posting the schematic now so that anyone who's interested can get a head start on building one - hopefully the complete software should be available over the next day or two. The PIC source code's up there too, should you feel like perusing it... I've burned a couple of test programs successfully, so I'm reasonably confident the hardware's ok. (That said, should any misfortune befall you as a result of using this programmer, I accept no responsibility!). In order to finish the thing, I need to know: (a) What is the SX assembler of choice, and what output format(s) can it produce? (b) If I support Intel Hex, is there a standard mapping for the FUSEX register in the same way that the 16F84 eeprom data is mapped at 0x2100 in MPLAB's output? Thanks again to those who assisted with the power supply side of things, and to everybody who's expressed an interest in the project. Cheers, Ben ben@codepuppies.com
