Sorry for the dupe, forgot the proper tag the first time around...

I plan on using a 6 pin Molex KK connector for ICSP on the target board.
Is there a commonly accepted pinout for this purpose?

Several people I know standardized on the Microengineering Lab's 10 pin
connector that comes off of thier EPIC programmer.  However, I soon ran
out of room for ten pins, and since they only use 5, I just use a 5 pin
inline header with ground, RB7, RB6, MCLR andf V++.  There really is no
standard, although you *should* standardize in *your* lab.

There are a number of programmer manufacturers present here, so maybe we
can create a 'defacto' standard? I have some candidates:
- the RJ plug used on ICD2 etc (a bit bulky)
- DB15 as used by my Wisp628, also the corresponding 2x8 pinheader with
1 key pin missing (DB15 is a bit bulky, even 2x8 takes a lot of PCB
area)
- 5-pin header (as shown in some uChip documents?) - disadvantage: no
key!

Please submit other candidates, vote, and use the result in your designs
and webpages!

Same here, just on a 100 mil pitch inline header. Or pogo pins. The RJ
connector is too bulky and expensive for one-time use.

If extra connections are needed, they are added to the core ICSP
programming connections.

I have logged into http://www.mouser.com and looked for some parts.  I see
these Mouser part numbers.

571-5551651       $0.53 AMP Modular Jacks
571-5551631       $0.60 AMP Modular Jacks
538-22-14-2064    $0.84 Molex 0.100" K.K. Connectors    (does this mate
with 538-22-01-3067 ? )
649-68685-306     $1.55 FCI Dubox PCB Connectors
517-850-01-08     $1.37 3M Board Mount socket (8 pin)


I am not drawn to the RJ connector, because of difficulty making cables.

I want to use sockets, not pins, on the PCB.  For mated boards, I would use
sockets on both PCBs and pins to connect them.  Don't have a representative
part number

I placed the 3M connector on the prototype PCB that I am working on, and
use jumper wires to the programmer.  It works ok.  I will have the Rev 2.
PCB specify a 0.100" X 6 pin area, add the PGM (RB3) to pin 6.  I will
order the 6 pin, and other parts that this list comes up with.

If all goes well, the Rev 2 board will show up in Nuts & Volts, so don't
feel shy (not that it's been a big problem)

Gosh, Aubrey, I've NEVER heard that before in my life. RJ11-6 cables can be
purchased in ANY Radio Shack/Best Buy/Walgreens. A crimper can be bought
NEW on Ebay BuyIT for $13. The wire is stranded #24. In the USA, its got to
be the most prevalent jack/connector there is. Telco requirements means
that both the jack and connector contact surfaces are GOLD.

And if you buy the RJ11 PCB Jack from surplus, you can get it for $0.15 a jack.
Microchip picked it for a GOOD reason for both ICD1 and ICD2.

We generally use a 2x5 header (.025 inch squre pins on 0.1 inch centers) because of the ease of crimping a ribbon cable onto the connector. We made a bunch of cables adapting these to the RJ connector Microchip uses. The extra pins (beyond pin 5) are used for I/O in our product. When not being used for programming, we also use the pins connected to RB6 and RB7 to temporarily connect to switches that are used in system calibration (if switch is closed on reset, system calibrates). On a product where we did not have room for that header, we used a single header with 2mm spacing.  The RJ connectors are nice, but BIG.

Hi-
This gets my vote, too.  However, the exact pinout needs to be defined.
Letting you use pin jumpers for calibration or i/o sounds useful.

Exactly.

You can crimp an RJ11-6 onto one end of the connector, strip the outer
plastic shell, then PRESS those wires into an MTA 5P connector.

I also have some tight designs on 2mm ctrs, but I mount the FEMALE on the
PCB, because its so hard to crimp the 2mm connector. So I just solder it to
a 2mm SIP header!

Bob,

I went back and looked.  Glad I could add a totally new perspective.

I had bought a grey PCB mount RJ-45 at Radio Shack a couple of years
ago.  I dug it out, and I am holding it now.  It matches pretty closely to
the drawing at http://www.mouser.com/catalog/specsheets/0415125.pdf except
that it is keyed.  With the change to RJ11-6 (or RJ12-6) this is what I
think the thread is recommending to use on the target PCB.

I think that this is not very friendly to a hobbyist because the
pins don't fit into a solderless breadboard, as they are not on 0.100"
centers.  I think that its important not to orphan the breadboard, or we
loose a lot of prospective colleagues.

I also had trouble keeping all the wires aligned before the crimping over
on the plug side.  I don't know if this gets better with practice or not.

I also have the Dallas digital thermometer prototype kit, and it has the
device mounted on little boards whose only purpose is to hold a pair of
RJ11 jacks.

I like the idea of the Olimex dongle, and the Olimex target boards because
they do use 0.100" headers (sockets) and in principle I can use them on the
breadboards.  However, I also suspect that Microchip's products are a bit
definitive.

I also looked in Mouser.  I do see several RJ11-6-4 parts, but no RJ11-6-6
parts.  There are several RJ12-6-6 parts.

So would the Mouser part 154-7623PCB (DGS) be in line with the developing
recommendation?  Would you use one on both the target and the ICD, and use
a straight through cable?

I use punchboards a lot. Their hole pattern is on 0.100" centers. I don't
think I'd use anything that deviates from that.

I use RJ-11 and RJ-45 quite frequently and once in a while with cable they
weren't intended for. Some of this stuff takes patience and careful
checking to make sure the wires are actually at the pin position they were
supposed to go in.

> I like the idea of the Olimex dongle, and the Olimex target boards because

Let's look at usage of this stuff. There'll like be a programmer or two in
the lab. Perhaps a couple ICSP cable to go with each. But that's about it.
So it really doesn't matter what the connector at the programmer end is.
Even making a "special" cable is no big deal, IMHO.

The number of connectors for target boards will far outweigh the number of
programming cables and programmers. So these should be as user friendly,
inexpensive, small and easy to use as possible. Sorry, but a RJ-11 jack
doesn't fit that requirement for me.

So here are the thoughts that went through my head when I thought about a
connector of the target board:

- Any complex connector with odd pinout or special mounting requirements
 wouldn't make sense. Chances are they'd be expensive, hard to find and
 difficult to use for anything but a manufactured board. This made DB
 connectors, RJ-11 or RJ-45 all unsuitable.

- A single row of 5 header pins would be versatile and simple but prone
 to accidents due to the lack of keying.

- A 5 pin Molex KK or AMP MTA (interchangeable?) are one step beyond the
 plain header as they add the key feature.

- A shrouded 10 pin IDC header is used for jtag in various places. It can
 be keyed and is easy to use.

Personally, I like the Molex KK or AMP MTA solution. It's inexpensive,
fits 0.100" centers, keyed, takes up fairly little boardspace (considering
the 0.100" pin spacing).

I didn't take issue with your choice, just the REASON for the choice. I
disagree that the connector is hard to makeup, That's all.

The RJ11 (or RJ12 jack) IS bulky. But it is reliable and easy to obtain,
that's all I was saying. The crimper is $13, whereas my Berg MiniPV pinning
cost (my standard 0.1" pin) more than my work car did (costs $900 new).

If you are trying to hit the hobbyist, I guess use 0.1" header pins and the
Tyco MTA connector.

Also, since I assume the RJ11 connector is only needed on one side of the (custom) cable, and assuming it's only a one-time thing, then why not just cut a pre-made cable, and save the cost of the crimper?

As a hobbiest user of PICs I've "standardized" my boards with a 10 pin
shrouded right angle connector. The pins are on .100" centers and the shroud
provides keying if I pay moderate attention (the mating connector can be forced on
upside down with very little energy). The mating plug end is IDC and the
connectors are more or less readily available at my local elec. shops. 6 pin
connectors are hard to find surplus. For a commercial product I would probably chose
some 2mm spacing smt part from HIROSE or someone else to minimize the
footprint.

I started with a 9 pin d-shell I/F (it accomodates all of Wouters Wisp628
signals) and its robust and definitely keyed but its not .100" centered and is a
little bulky, but I/F cables were liberated from old xt motherboard machines
rs232 cable conn.

My conclusion as to why Wouter chose a 15 pin d-shell (aside from its spare
game port cable roots) is because he could route all 8 of his signals on one
side of his PCB without using a more expensive right angle DB-15, which was
clever but an overkill in my opinion. Besides its tough to emulate on a
point-to-point wired circuit...

Don't miss the most important point: it takes up very little (precious)
PCB area!

But I certainly don't advocate DB15 as connector at the target side, I
prefer a 2x8 pin header (when I have one at all, because a DIP clip is
much easier and I use mostly DIP).
