 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Finally received my Pickit 3, (34 day delivery...). Went to download the software & noted it's about 550Meg (Version 3.26). Geoff's page about programming PICs mentions it installs a lot of unnecessary stuff & I notice his example is using Version 2.26. He also mentions that all really needed is the "MPLAB IPE". Noticed there is a stack of archived version on the site and just after an opinion on what's best to install? As long as it's easy & does the basic job. Just go with the latest version or do others have preference for an earlier version. MPLAB X IDE Only think I've ever flashed before is the old WRT-54G's that were crippled at on stage & needed firmware loaded via the J-Tag header & a home brewed parallel port adaptor, (if I recall correctly. Thanks Phil. (Have the SnadPic & a few 28 Pinners). Thanks Phil |

Hi Phil Google MPLAB IPE download it is all that is needed with Pickit3 and is uptodate with current pic micros. Several site show it as a separate download to MPLAB IDE Chhers WarwickG |

Phil, Go ahead and load the current MPLAB IDE from Microchip as it includes the IPE with it. Also check out this thread in order to verify your PIC writes. This is the important bit from bigmik: --Curtis I am not a Mad Scientist... It makes me happy inventing new ways to take over the world!! |

Hmmm, Not getting a result yet. Any suggestions on this error. *****************************************************

It happens whenever the programming pins are (excessively) loaded by other devices/components than the PICkit: are those (pin 4 and 5) connected to anything but a 2K+ resistor or other IC input pin (especially capacitors, low impedance loads such as a LED, another IC output pin, etc) ?... If the answer is yes, then you can't program the PIC in-circuit unless you can disconnect the offending load (I usually use the MM pins 4 and 5 as outputs, or connected to a load that hooks to the board via a connector, and can therefore be disconnected during reprogramming of the PIC). |

I find I have to unplug the PicKit3 and plug it back in a couple of times before it will decide to work. Sometimes just closing the software down and re-opening it works as well. Dave. |

It was just a bare MX170 plugged into a bread board & connections to the programmer made with 10cm jump leads. Absolutely no other components. I was powering it from the Pickit3 with the "Power Target from tool" option, and it seems that was the issue. Plugged a 3.3/5.0 volt module in and it programmed fine. Thanks. |

MPLAB X and PICKit3 were the beginning of the decline for Microsoft, especially in terms of ease of use. Cheers Chris http://caroper.blogspot.com/ |

You still need a capacitor on the VCAP pin. Having a more powerful power supply can mitigate the need. Microblocks. Build with logic. |

Hi Phil, I was about to reply to power externally with 3v3.. but I see you have worked it out (deselect power the device though so there is no problem with two power sources fighting each other... I have only ONCE got a NanoMite to program using the PK3 power source.. But mine is a clone. Maybe the genuine PK3 is better in that regard. I now always supply external power.. Kind Regards, Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |

Yes, it happens too. In fact it depends on the order in which the PIC and the PICKit3 are powered up. To ensure reliable comms between the two at the first try, I now proceed as follow: - I power up the PIC. - I stop its BASIC program if it was running and issue a NEW (to reset program and all the pins to unconfigured state). - I unplug in the PICKit3 from the PC USB port if it was connected. - I plug the PICKit3 into the ICSP connector of the board with the PIC to program. - I plug the PICKit3 into the PC USB port and let it initialize fully (watch its LEDs, and wait for the red one to light off). - I start MPLAB IPE and/or "Connect" from it. This time (and for once  ), it got nothing to do with Micro$oft... I'm using MPLAB X under Linux here. and you could also use it under MacOS-X. It's a Java application. |

Until i made my own programmer i always used the PK3 to program the chips directly. I put a ZIF socket on a piece of board and only connected a cap on the VCAP pin. Without the cap, 80% failure, with it never a failure. Once in a circuit things can get more difficult. A cap/diode/resistor on one of the programming lines can really mess things up. With the PK3 you get a poster that has the requirements on it. Follow that and no problems. Microblocks. Build with logic. |

Yes, I meant Microchip of course but Microblocks had already posted so I could no longer edit my post to correct it. I still primarily use the PICKit2 and have an ICD3 in my top draw for stubborn problems. PICKit3 generaly sits in PICKit2 Emulation mode on my desk. Cheers Chris http://caroper.blogspot.com/ |
