| Limitations of ICD2 with CCS |
 Posted: Thu Apr 29, 2004 7:06 am |

Hello everyone,
Is there any limitation in debugging CCS code, using ICD2 from Microchip ?
Thanks,
Gabriel.- |

Thanks PCM for replying.
I need to run the ICD for using an 16F88.
And what would like to know, if with both ICD's I will be able to watch variables, RAM, ROM, etc, when the program runs.
Also, donīt know if Microchip's and CCS's already come with a 18pin adapter included.
I would apreciate any information.

Microchip has a list of the devices supported by ICD2, here:
http://www.microchip.com/1010/pline/tools/picmicro/icds/icd2/detailed/index.htm
However, I don't think that list is current, because in MPLAB vs. 6.42,
in the ICD2 Help window, it says 16F87/16F88 are supported by ICD2.
CCS also has a page where they list devices supported by their ICD:
http://www.ccsinfo.com/icddevices.shtml
It doesn't list 16F88, but maybe their list is also out-of-date ?
You should email CCS and ask them about it.

We bought two of the Microchip ICD2 units. They don't come with
any adapter.
I'm not sure why you want a 18-pin adapter. Normally (at least for me)
the ICD2 is used for "in circuit" debugging or programming.
You directly connect the ICD2 to your printed circuit board. You can
do this by putting a 6-pin modular jack on your board, such as Digikey
p/n A9031 (AMP 555165-1), which looks like this:
http://catalog.tycoelectronics.com/TE/common/images/PartImages/2619007b.jpg
or you can put a 6x1 header on your board and make a cable adapter
for the ICD2. I did this. See below.
---------------------
The ICD2 comes with a 6-pin modular cable, about 40 cm long.
It looks something like this:
http://qcpusa.com/tdv-modular-cable.html
I bought an adapter from Digikey, to convert the 6-pin modular
connector to a DB-9. Here's a photo:
http://rocky.digikey.com/WebLib/CUI%20Inc/Web%20Photo/AMK-0003.jpg
It's Digikey p/n 046-0003. http://www.digikey.com/
Then I built a short adapter cable to convert between the DB-9 connector
and a 6-pin Molex connector. (Digikey p/n WM2004) Photo:
http://rocky.digikey.com/WebLib/Molex/Web%20Photos/22-01-3067.jpg
Then, on your test board, you can put in a mating Molex connector
(Digikey p/n WM4204). Photo:
http://rocky.digikey.com/WebLib/Molex/Web%20Photos/22-23-2061.jpg
On your production boards, you don't install that connector.
You take a 6-pin piece of ordinary break-away header and insert it
into the Molex header. Then you push it into the 6 holes on your
circuit board and press it on the side. This allows it to make contact
with your board while you are programming it with MPLAB and the ICD2.

-----------------------------------------------------
I don't own the CCS ICD, so I don't know if it comes with any adapters.

Edited on 5-3-04 to change a Digikey p/n to the correct one: A9031

PCM,
Thanks a lot for this information.
As seen from the connections from the ICD2 to the circuit, you connect via 6 pins to the target board, in wich YOU HAVE NOT TO TAKE OUT THE PIC MICRO FROM THE BOARD, isn't it ?
Two of the ICD2 pins that are used are PGM and PGD, wich go directly to T1OSI and T1OSO. So, I wonīt be able to use TIMER1 via an external 32,768 cristal when using the ICD2, isnīt it ?
Well PCM, this is the last question I will ask about this. Thank you very much, and hope not to bother.

That's true. The ICD2 uses those two pins during debugging. |

Thanks again for the part numbers PCM. I just went and found all the parts using your instructions. Here is a summary of all the parts and i also added the crimper and the pins that you need and price info.
Index Quantity Part Number Description Unit Price Total
Connector which gets crimped:
1 10 WM2004-ND CONN HOUS 6POS .100 W/RAMP/RIB 0.46600 $4.66
Pins for Above:
2 30 WM1114-ND CONN TERM FEMALE 22-30AWG TIN 0.07400 $2.22
PCB Connector (First one is straight, the second is Right Angle Mount):
3 10 WM4204-ND CONN HEADER 6POS .100 VERT TIN 0.58600 $5.86
4 10 WM4304-ND CONN HEADER 6POS .100 R/A TIN 0.93000 $9.30
Universal Crimper:

There are also little RJ11 to pin-header adapter boards available.
I don't have the link to that thread right now, but I know Mark
mentioned them on the thread, and I also found links to commercially
available adapters. Maybe I can search for that thread tomorrow.
The method you're proposing to use may be the best for your
application, but I want to make you aware of all options. |

Here's the thread where I posted four links to companies
that sell ICD2 adapters that convert from the RJ11 to a 10-pin
header connector.
http://www.ccsinfo.com/forum/viewtopic.php?t=20828
I use the 6-pin header that I described in my post earlier
in this thread, but I wanted to let you know about the other adapters. |

For anybody that ends up viewing this thread, it looks like the Digikey A9031 part listed above has been replaced by the ROHS compliant part A31422-ND (which is also listed as a 5555165-1 (one more "5" than the part listed in the above posts)). They show it as $0.93 each or $0.81 each for 10 pcs as of 28-Dec-2012).
