Hello,

I have made a ICD2 from the original PICS (rev B) -a guy-. Because i couldn't find the components that he used in my city, i duplicate the schematic (it wasn't provided) changing the components, route and track width to suit home-made tools. I tried to compress the pcb but it was a hard work incompatible with standard home-made techniques (especially if you use the transfer-tone method).

The ICD2 clone is full working and tested with MPLAB 7.4 and 8.x (for now MplabX sucks):

Note: pcb is supplied with two copies of same circuit for home made purposes: i used two layers to insolate my pcb because couldn't get total opacity with printes. You can use only 1 if it's dark enough. 0.3 and 0.5 are small holes to aid in centering the drill. Read notes.

no pass

Follow the next steps to make it work:

0. Build PCB :D
1. Install MPLAB
2. Program 2 pics with supplied firmwares. Be aware of configuration settings when burning the code (watch images)
    I use winpic.

   Note: MCLR/RE3 is disabled in code

4. Plug the ICD2 to PC, then:

   a- device will be enumerated (ding!)
   b- drivers will  begin to be installed (MPLAB must be installed previously)

5. Launch MPLAB

6. Select like programmer ICD2 in menu

   *** DO NOT TRY TO CONNECT IN THIS STEP  ***

7. Enable the option "Download operating system". Select the OS to be used for the 877A:
   (by default MPLAB  shows the one .hex suitable for our pic). It will download the OS to 877a

   Message windows will report:

   Downloading Operating System
Connecting to MPLAB ICD 2
...
   Connected
  
Setting Vdd source to MPLAB ICD 2
...
   Reading ICD Product ID

   Running ICD Self Test
...
   Passed
...
   Download Operating System Succeeded
MPLAB ICD 2
   Ready

8. Check volta ges all is correct :
 
   Programmer->Settings->Status-> All tests passed
   Programmer->Settings->Power
         Target Vdd: 4.96  (must be 5V aprox)
         Target Vpp: 13.02 (must be 13V aprox)
         MPLAB ICD2 Vpp: 13.02 (must be 13V aprox)

   All perfect and in range.

9. NOW CAN CONNECT WITH ICD2.
   Push the button Connect.
   The first time it will downdload the OS specific to the target (target PIC connected to icd2)

   For example:
   MPLAB 7.4: ICD12010200.hex


I made and tested it. All the previous steps are verified several times and all is ok without anyproblems.

Notes:
- I provide the files without any warranty. Used by your own risk.
  If have some problem, check edaboard forums: http://www.edaboard.com (note that spawn and illegal contents are not tolerated). Try to search ICD2 clone.

- It's noticed that in some circuntances firmwares could be corrupted (also in original clone circuit). Usually if ICD2 is disconnected without closing MPLAB, USB glitches can put pic in programing mode and fw becomes corrupted. Some people have reported it effects, others haven't.
You'll have to reprogram the 877A and download the OS again. It will fix all (temporary sol). If you experiencie this issue frecuently then:

I recommend, closing first MPLAB and after, disconnect the ICD2 clone.
Check new files updated with further information about it and apply the suggested changes in notes to solve these issue.

Enjoy.

Regards.

Any schematic & PCB file in eagle format (your version)  ?  ....  ;)

Have you test it on 3.3V Chip ??? i see that it couldn't work on these chips

Nop, it's is not tested with 3.3V. You need a level adaptor from 5V->3.3V.

Why? I made it some time ago and didn't need 3.3V support. Anyway the original PICS-b can't support 3.3V pics natively, you need a level adaptor. I have a icd2 pcb with minor changes to support it from a friend (but only the PCB in pdf format to be printed). But I need to search it betewn my DVDs xDDDD

If need a clone with 3.3v support, then can make pyoto clone (www.icd2clone.com , here also can find the original PICS b). But i haven't test it.

I forgot to tell that  my version works perfectly in debug mode.

If need eagle sch, try in edaboards forums. I posted them there,  but don't know the exact link. Look for alunaro nickname, and search "icd2 clone". It one of my nicknames in other forums :D
Will look into my dvds for a level adaptor. I have one (at least the schematic, it's very simple).

yes ICD2 potyo sopport 3.3v dspic.!!!!!!!

Can you share over here (the working version) ?

i' make a potyo2 board but no recognise the pics  >:(

My ICD2 clone is full working, its based in PICS(b). I didn't like Potyo because read many posts about problems and is more complex, therefore i don't need 3.3v support.

You can easily add a level adaptor to PICS version.


Notify if links become broken. I revise my posts from time to time... ;)

Really is ***ing annoying that i can't read my own links....
"You are not allowed to view links, check the Announcements Board"

:/

dear alichan.

did you changerd rj connector from picS orignial design?
because this RJ is not rj12 :P

i am editing the PICs design with corel prior to correct this mistake....  so the board is very tiny

HI alichan.

Yes, I follow your ICD2 schematic & Firmwares, it is fully working, but has yet to test 3 V!!

to: jeanninemtv

I adapted the board for making at home. I have no tools to make so thin tracks or pad (neither some friends). Size of board increased, but is aceptable and now can be done without any difficulty with simple tools.
About the connector the story is that i couldn't find such in stores of my city. Soa i changed it for a connector more usual (at least here and think in whole world). But shouldn't have problem with it because footprint is standar and holes too.
Maybe i should have used only a SIL connector. But that is another story...


to jack12345:

I repeat, it doesnt support 3.3V natively. You have to use an adaptor.
I had the schm but... couldn't find in my CDs. Sorry.

Hi all,

I came accross this web site and found some very cheap hardwares.

http://www.freewebs.com/batbatdieu/

They have ICD2 for $350,000 VN dong which is about $21 USD (one USD = 16000 VNdong).

I have no idea where will they will ship (international or not). But for $21 USD not a bad deal.

The thing is not an English site. It is Vietnamese.

Tom

Oh! I now have the icd2 can programer 3 volts, because there is no connect Capacitance [Vddcore  --||---(104)], Thank you! Sonsivri forum my friend!

Tom

this is good. it is fully working, but has yet to test 3 V

i am confuse , cant find any 3.3V converter from microchip? here a 16-Bit 28-Pin Starter
Development Board User’s Guide.

http://rapidshare.com/files/102758504/DS-51656A.rar

microchip in his starter guide to icd says

dont support LVP...  need conditioning of signals...

did u read full pdf ?  ???

The 16-Bit 28-Pin Starter Development Board has the option of being powered by a 9V
DC power supply or by the USB bus. The position of jumper JP1 determines which
power source is used. Connect jumper pins 1 and 2 for the 9V power supply or jumper
In addition, jumper JP2 selects either a +5V or +3.3V power source for the targeted
device. For dsPIC30F devices, connect jumper pins 1 and 2 for the +5V operation. For
dsPIC33F and PIC24 devices, connect jumper pins 2 and 3 for the +3.3V operation.pins 2 and 3 for the USB.


All dsPIC30F/33F and PIC24 devices use a pair of I/O pins (PGCx/EMUCx and
PGDx/EMUDx) for initially loading your application program into the device, and for
communicating with the MPLAB ICD 2 In-Circuit Debugger. Typically, these pins can
be used by your application program for other functions after your program is loaded
into the device. However, these application functions are not available while you are
connected to the MPLAB ICD 2 for debugging.
To circumvent this issue, most dsPIC30F/33F and PIC24 devices use one or more sets
of alternate pins for MPLAB ICD 2 communication. These alternate pins are identified
as EMUCx and EMUDx, where x designates the number of the pin pair. By selecting
an alternate set of pins for the MPLAB ICD 2, you can safely use the original I/O pins for your application.

the version of potyo 2 if bears devices of 3.3v the version of PiCs not or unless adapt him itself a factor of tension

You Have textoll SCH for multiprogram chip ?

You can chekc this site for not so expensive development tools http://www.olimex.com/dev/index.html

I upload schematic and pcb layout of PICS(b) that i created (eagle 4.16 r2). I forgot it, sorry.

Real pcb: (http://img119.imageshack.us/img119/2141/icd2uc5.png)

Better later than never ;)

Remember, it doesn't support 3.3V mcus. Add some level adapter for it. Check the TESKAn's pdf, it's based on   PICS(b) and has a level adapter (but i haven't the layouts).

I gathered some notes from several sources and added others from myself, that help to the circuit stability and could avoid some problems (if they appear -not my case-). Notice there are hardware modifications and others related to the programming stage (fuses mainly)

1) R=10k on MCLR on F4550 is better -even though the firmware in Version B sets "MCLR Disabled for Pic18F4550"-
    1b) If you are really bored you can replace R1=20K with multiturn pot. 22K and do the job: adjust on 12,5V and that is.
2) C=10pF o 12pF for crystal (C6 and C7). (important)
3) C=330nF replace with 100nF and add in parallel 4u7 (elco) for V_USB (+5V) (C8) (important)
4) add 100nF capacitors on USB connector, on F877A and on F4550 (important)
    -between VCC and VSS- (pins 31-32) otherwise could appear problems of communication with MPLAB before unloading the SO the 1st time. These are our lovely decoupling capacitors...
5) osc=RC for F877A (very important) -notice the xtal is for the F4550 and the F877A uses an osc-
6) use 1N4148 instead 1N5819 (not important)
7) use BC327 and BC337 (not important)

These points should be more than enough... but  if you have some problem i suggest taking into consideration the next points:

(*) 8) inductor can oscilate between 100µH to 1mH. Tested values are 100µ-180µH (ver datasheet del MC34063A)
(*) 9) set all sectors unprotected for write when burning firmware.
(*) 10) when debugging uncheck Power target circuit from Mplab ICD2 (5v VDD) to avoid errors on mplab.

Suffering from reset of pic 4550?

1) Only after Windows is on plug in usb on ICD2
2) Only after Windows if off unplug ICD2 from usb
3) Only when is deselected ICD2 in menu in MPLAB disconnect ICD2 from target pic

If something from points 1,2,3 happened just clean USB driver and reinstall again.

In my opinion adding the MCLR resistor, decoupling capacitors, and the notes about capacitors are the most important and easy to add to the circuit -even if it's already made in the pcb-

Regards.

hi alichan

can you re-upload archieves again? (ICD2 for any pic -3.3V- (TESKAn).rar and ICD2_layouts_Eagle4.16.rar )

thanks

Re-uplodead (like matrix but without f****g machines) ;)

Check 1st post in this thread, links are fixed and new uploaded. I don't like polluting threads...

One think i hate deeply is information when it's not well organized, something easy when threads are growing... i tried to sort all (think about the different sources i managed) to make it compreensive and easy to follow.

Anyway K.I.S.S

cya.

I have seen may clone on internet but confuse to choose right one can any body tell me is it better to use PIC18F4550 OR USB TO SERIAL IC LIKE FTDI .Is there is speed difference between CLONE WHICH USE pic18f4550 and those which use FTDI IC .Also tell me what is purpose of PIC18F4550 is it is used as rs232 to serial convertor ?

18f4550: Full Speed, USB 2.0
FTDI: Low, Full or Hi speed USB 2.0 depending on the chip.  (http://www.ftdichip.com/FTProducts.htm)

I haven't used the FTDI chips so i can't say much about them. Think about the PIC has native USB but the FTDI behaves like an UART, therefore you are limited to only a kind of possible configuration whereas the PIC can be configured for the 4 different working modes of the USB.
Resuming, FTDI is intended to simply the interfacing and focused in the communication and the PIC is real USB so you can create different kind of USB devices (HID, CDC, etc.).

If you see a PIC with USB support surely it's being used for REAL USB communication, not like a rs232-usb conversor (for that the FTDI and other chips were invented). Of course you can use the PIC in such a way but... it's a waste unless you need special features.

For simplicity of FTDI and i have also breakout board so i want to use FTDI but i have also option of using PIC MICRO. So
infrom me in which mode PIC18F4550 ICD2 CLONE Is operating,CDC,OR SLAVE PARALLEL PORT OR RS232

Its long since I read the Datasheet for 4550 but as far as I remember its parallel port but I would suggest why not go through datasheet before asking such question
