if this has been thrashed a bit already forgive the redundancy. my dev partner and I are having a bit of a time of getting the ICD to work.
we have a pic18 series->level converter->computer comm port->PCP
we then compile for ICD ops, ICD run, then bring up the serial communicator and viola, nothing is displayed. the program is a very very simple, short one using "hserout' and 'hserin" in a loop.
so, are we making this ICD too complicated or what?

The text below is copy / pasted from the Microcode Studio Plus help file, if you are not using the plus version it only supports one chip:<br><b>
MicroCode Studio uses an ICD Model in order to initialise and control the operation of the ICD for a given PIC microcontroller.
MicroCode Studio Plus
The ICD for MicroCode Studio Plus supports the following PIC microcontroller devices.
16F627(A), 16F628(A), 16F73, 16F74, 16F76, 16F77, 16F870, 16F871, 16F873(A), 16F874(A), 16F876(A), 16F877(A), 16F87, 16F88, 18F242, 18F248, 18F252, 18F258, 18F442, 18F448, 18F452, 18F458, 18F1220, 18F1320, 18F2220, 18F2320, 18F4220, 18F4320, 18F6620, 18F6720*, 18F8620 and 18F8720*
* Please note that for these devices, the ICD will only support the first 64K of your program.
MicroCode Studio
The ICD for MicroCode Studio supports the following PIC microcontroller devices.
16F628
Please note that the ICD is not enabled if using the demonstration PICBasic PRO compiler. If you would like to purchase MicroCode Studio Plus, please read How to Purchase MicroCode Studio Plus.
pic = 18f252 I/SP
MCS+ = 3.0.0.5
PCP = 2.46
should be supported, yes?

I've attached a screen capture of the above running in MCS+ ICD. Tested on anCode:DEFINE LOADER_USED 1 ' using MCS+ bootloader

If you still have trouble try blinking an LED with the ICD just to make sure you have
everything setup properly.
got it. thanks.
also looked at this that helped ;-)

It's tough to offer help on source code I haven't seen. Can you post the code you're having problems with?
Bruce, to simplify things so I can figure out what is going on, I am running the MCS+ ICD for a rather simple program, for which I have attached the code at the end of this posting.Quote:

Another problem I am having intermittently is that sometimes the ICD Run shows what is titled as an "ICD Message" as shown in the second attached image. It doesn't happen all the time, but when it does, I don't understand what is causing it or how to fix it. Since the ICD is apparenty very sensitive to having the clock specified correctly for it to run, I thought it might be that my OSC speed wasn't properly specified in the configs and the DEFINE OSC 16 statement, but I double checked this and it appears correct.
If you can help me figure out these two problems, it would be greatly appreciated.

I think you might need to actually declare a few variables if you expect MCS ICD to show them...;o)
I don't think MCS+ ICD is smart enough to yank variables from include files. That + ZERO support is
why I no longer use, nor recommend, MCS+ ICD.
pssst... so... just between you, me, and that lamp post over there... What do you use and recommend?Quote:

If I need to know specific timing for time critical routines, I'll use MPLAB/MPSIM software simulation. Testing on hardware, I just build it & test the code on the hardware it's going to run on. Haven't seen any software yet that acts 100% the same as hardware..;o)
MCS+ ICD used to be a pretty cool option, but support for it seems to have dropped off the planet.
Thanks Bruce,Quote:

I just "build the hardware and run it" and if I've got a extra few pins I'll connect a LCD display so that I can show the values of select variables.
Just curious what the "experienced users" use. Thanks!

OK, I could understand that no Variables Tab would show if no variables had been declared. However, here is another program in which many variables were declared. I have also attached an image of the MCS+ screen while the ICD was running that shows it stopped at a breakpoint....but notice that even though the variables are declared in the program no Variables Tab appears in the ICD Explorer window. So the problem is still there.Quote:

or maybe a bad ICD model file?
Sorry I can't offer more help, but I haven't used MCS+ ICD in years.
Have you tried contacting Mecanique for tech support?
I pasted your code into my MCS+ and ran the ICD and it still doesn't show the Variables Tab (see attached image).Quote:

I am also going to send your image and my image to Mechanique and ask them what is going on. I really appreciate your help on this
MCS+ 3.0.0.5 on Windows XP.
Bruce, if you would be so kind, would you please put your cursor on each of the four icons on the right end of the 1st Tool Bar line of your version of MCS+ and then tell me what their individual descriptions are? Once I know what these missing icons are for I want to ask mechanique why they don't appear on my version of 3.0.0.5 when running XP.Quote:

Thanks to Darrel Taylor's response at techsupport assitant at meLabs, I have solved this mysterious problem. Let me explain, because this may be encountered by other users of the Micro Code Studio Plus (MCS+) ICD.
It turns out that the ICD model that came on my CD-ROM that delivered MCS+ to me was not correct for the 18F4550. Darrel had downloaded this .inc file from the Beta models and emailed it to me. When I replaced the ICD model I had for the 18F4550 with the one he sent I started seeing Variables Tab.
The icons I thought I was missing in the tool bar only show when using a boot loader, as explained by Bruce Rentron in above post.
Chasing down this problem took 3 days out of my time....no thanks to Mecanique's tech support who never responded to my emailed request for support.
That was one of my suspicions, but I'm glad you got it sorted.

It seems to be an on-off kind of thing. Or it depends on if it involves any sort of time-investment for them/him, I don't know.
When I had problems with MCS+ and Win7-64 I emailed them and got zero response but thanks to Darrel and Charles that problem too got sorted. A month or so later I emailed Mecanique again inquiring about a bootloader file I didn't have and got a response (and file) within hours.

Any help please.
Regard's
You can't use the ICD with the PIC running at greater than 40Mhz.
There's no real reason other than MCS+ won't let you.
But, you can increase the divider so the the core runs at a lower freq.
_CPUDIV_OSC3_PLL4_1L will give 24mhz.
Then change to DEFINE OSC 24.
Also, the ICD is not compatible with standard USB routines.
It will likely drop the connection to the PC because it's not servicing fast enough. (Unless using USB_ASM_Service.pbp)

OK Darrel ,Quote:

That is problem in PBP ICD 100% but we or I cant edit .ICD file for new devices...
I was probe your suggesst an work 100% ok. :cool:
