Hi there. For What It's Worth: I'm currently using a PICKit 3 doing full debug=20 on a PIC16F1783 and 1784 (two different projects)=20 under Windows 7. One computer is a tiny netbook=20 running Win 7 32-bit, the other computer is a=20 full-size laptop running Win 7 64-bit. Both work well - both for debugging the chip=20 directly as well as using what Microchip calls=20 the "Emulation Extension Pak" (AC244064). The=20 other name for this device is "Emulation Header" and it is truly awesome! This board has the pic16f1789-ME2 bond-out chip=20 on-board. If you use the board with a PICKit3 or=20 ICD3, you get 32 breakpoints and some other=20 really nice features. But if you add a Real Ice=20 to the mix, you get pretty much all of the=20 features of the old ICE2000 emulator: unlimited=20 breakpoints, full trace capability, multi-level breakpoint triggers. Do note that using the Emulation Header with the=20 bond-out chip requires MPLAB-X. Generally=20 speaking - I'm using MPLAB 8.92 directly with the=20 chip unless I need the extra resources that the=20 bond-out chip brings to the table. I'm doing most of my development under MPLAB 8.92=20 and Win 7 because I'm still having major problems=20 running MPLAB-X under Windows 10. Stupid things=20 like the assembler not properly dealing with macro expansion and such. I'm not comfortable with MPLAB-X. I truly wish=20 that the people who designed the debug user=20 interface had maintained the same function-key=20 assignments. Some of the new key assignments are just plain annoying! Bottom line is that I'm not having any problems=20 doing in-circuit debug with the PICkit3 under Win=20 7 when using the 16f178x family. dwayne At 05:19 AM 1/4/2018, David C Brown wrote: >Content-Transfer-Encoding: base64I have tested=20 >the same set up on a desktop machine running Win7 and it >fails in exactly the same way. >I have also tested it with the shortest possible cable - less than 5cm - >and still get the failure so I doubt that cross-talk is the problem.d >The logical conclusion is that, whatever Microchip say, MPLAP8.92 is not >fully compatible with Win7. >For XP emulators the lord be thanked :-) > >__________________________________________ >David C Brown >43 Bings Road >Whaley Bridge >High Peak Phone: 01663 733236 >Derbyshire eMail: dcb.home@gmail.com >SK23 7ND web: www.bings-knowle.co.uk/dcb >On 4 January 2018 at 02:25, Isaac M.
