This is what I built myself for Christmas to make programming MicroMite's easier:    It can program any ONE device at any one time, but can program the standard 28-pin chip and the 1455 USB chip in DIL and SOIC flavours. The last photo shows the board fully-loaded with all chips, but you can't actually program it like that, that is just so you can see mainly the SOIC chips loaded in the sockets. I plan to offer programmed chips on the website next year, but probably only the DIL ones. The SOIC sockets are just to make my life easier for assembly stuff, but if there is any interest, I could keep a small stock of programmed SOIC chips. I see the breadboard-friendly DIL chips being more popular, but that is just me. If anyone is interested in a constructors pack for this thing, let me know and I will compile one and upload it to my website sometime over the Christmas break. Smoke makes things work.

GDay Grogster, Nice, I always wanted to do something like that as currently, I have a MuP with a ZIF socket for dip28, and a separate adapter panel that I ‘bodged’ to do the 14pin dip. I have twice now spent quite a bit of money buying a ZIF socket for the SSOP chips but I have never been able to actually get the PIC32 into the socket... pin spacing were correct and the chip would `almost’ drop in but just not quite... i wrecked one socket thinking I could force it to open about .25mm more to let the chip fall in but it is like the SSOP is fatter than a standard one. Where did you source your SSOP socket from? Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |

Arrghh! I just re-read your post and yours is for a SOIC chip.. Does anyone know of a source of SSOP sockets that will take the SSOP 28 PIC? Regards, Mick EDIT*** My plan was to have a small m/b with the support stuff (power, VCap, ICSP, resistors etc) and then design a series of drop in boards for each device (inc the 44 and 64 and possibly other flavours) Mik Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |

Hey Mick.  I got both my soockets from KZT Socket Store on AliExpress - they sell just about anything you can think of socket wise. 14-pin SOIC socket 28-pin SOIC socket ...and they do one for your 28-pin SSOP that you want....  That link is for the SSOP with 5mm body width to match the PIC32 in SSOP, but be aware that you can easily buy the wrong one, as they also do a SSOP28 in 4mm body width, so make sure you either get the one above, or if you are looking elsewhere, make sure the pin-count and pitch are what you need, and ALSO the body width.

Hi Grogs, A BOM would be great did you have any extra boards made. I have been doing SOIC by soldering wires to them and breadboarding. Paul. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

I can whip up a BOM for you. I got ten boards, so have nine spares left if you wanted one. Smoke makes things work. When the smoke gets out, it stops! |

Yes I will have one, what cost and I will PayPal. Paul. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

Likewise Grogs, I would like one too. Not the sort of thing that anybody else is likely to want 10 of, so a Constructor'sPack probably isn't worth doing. Better to get more boards yourself, if demand is there, and sell them? Bill Bill |

OK chaps, US$5 including airmail anywhere to <sales@rictech.nz>. Additional boards in the same envelope US$2 each. Example: two boards for US$7 including airmail anywhere on the planet. There are nine left. Any ordered right now will probably suffer postage delays due to Christmas - just be aware of that. If these ones dissapear, I will get some more. Bill is probably right - maybe not worth doing a constructor's pack....I dunno....  EDIT: I am ALREADY thinking about making the board 100x100 and adding sockets for SSOP, 44-pin QFP, 64-pin QFP and 100-pin QFP. But where do you stop?(rhetorical!) Probably not a sane idea, as all the QFP's can be programmed easily once installed on the board. Especially if the board employs the 1455, and I think this is pretty much the accepted standard configuration now, eh?! Smoke makes things work. When the smoke gets out, it stops! |

Well, if you did need to order in more boards, and in this day and age the 10 pieces of any board 100mmx100mm is becoming the norm for our Chinese pcb manufacturing friends, then it may well be worth the effort to add the additional sockets. Presumably, a constructor would only need to install the socket types he or she needs? I have ordered one of mk(i) but would probably add a mk(ii) to some future order, if they became available, Grogs. Bill Bill |

Bill - correct. If you don't plan to ever use a certain socket, just don't bother installing it. Essentially, ALL chips PGD, PGC and MCLR lines are connected together so that you can program anything in any one socket - but only one chip at a time. 100x100 PCB's are exactly the same price as 50x100 so there would be no cost difference per board, but 100x100 is bigger then the DLE envelope, so postage would cost more to send to people. If I made it 150x50 the PCB price also shoots up dramatically(US$27 for ten vs US$5 for ten!). You need to stay inside those two sizes. (50x50 or 100x100) Something to think about over Christmas...... Smoke makes things work. When the smoke gets out, it stops! |

Well, it seems the ALLPCB deal of $5 for 10 off of a 100mmx100mm pcb, including free DHL shippiong, has come to an end. Fortunately not before I ordered Grog's Message-Mite and his PIC16F1455 USB/Serial and ICSP boards. The latter have arrived, the former are on their way via DHL. ALLPCB ratesare now US$10 for 50mmx50mm, including DHL shipping and US$20 for 10 100mmx100mm. Still fairly cheap but the increased cost is something to bear in mind. Bill |

That's still a good deal when you factor in DHL shipping, IMHO..... Smoke makes things work. When the smoke gets out, it stops! |

another option, according to my mate who put me onto ALLPCB, is www.jlcpcb.com, who offer an even more amazing deal on 100mmx100mm double sided, just US$2 plus shipping.The shipping options there include China Post, at around $8. OK if you don't mind the longer delivery time. Bill |

| Bill7300 Senior Member Joined: 05/08/2014 Location: AustraliaPosts: 159 |
that is $2 for 10 boards. Bill |

Are you using a PICkit or can the MicroBridge do? |
||||
| Grogster Admin Group Joined: 31/12/2012 Location: New ZealandPosts: 9750 |
The MicroBridge based on the 1455 chip can be used to program the DIL or SOIC MM2 chips. Or any other PIC32 chip in those footprints, for that matter. The MicroBridge based on the 1455 chip CANNOT be used to program more 1455 chips. For the 1455 chips, you need a PK3 and the IPE software. The latter is why I did not bother to embed a 1455 USB interface on the programmer board, as it would only be able to do the PIC32 chips, wherease a plain ICSP header will work for either PIC32 or PIC16F series.

Finished my Program-A-Mite and it sure makes life easier programming SOIC chips. Thanks Grogster Paul. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

You are most welcome. I hope it proves useful for you. Smoke makes things work. When the smoke gets out, it stops! |

i have some code to program a 1454 with a 1454. If you add a socket for a 1454/1455/1459 the those could be programmed also. It just needs some time to get it into sharing quality. :) Microblocks. Build with logic. |
