The Unicorn and Inchworm combine to (using the high speed PSP port) to emulate a typical ICD2 USB clone.

You want something simple build a Junebug. The single 18F2550 is much easier to build.

you are right dear but i have to build ICD
please tell me the way how do i combine both
to make USB ICD+COM Port ICD
Do u have a combined schematic
In Unicorn Assembly Instruction (Page 5, Schematic)
These is "40PIN +inchworn+interconnect CON7)"
but there are 18 PIN from (18F4550)
I understand that PORTD of 18F4550 to be connected with PORTD of 16F877A
but where to connect PORTE, RB3, RB4, RC0 of 18F4550
Please advice if there are some other modification to make
I only want to make Programmer/Debugger and Not interested in USB-KIT
I am waiting for you answer

Added after 3 minutes:

I in My Place only have PIC18F4550 not 2550
so will Junebug work for this

Hi, maybe this can help you a little...

I had the same trouble when I built my ICD (PIC18F4550)...and the reason was the Crystal Osc.
it was dead. So, I replaced it and the ICD started to work.

 

[saeed_pk]

winpic800 settings icd2

This ICD have one crystal for both 18F4550 and 16F877A
do i use two separate crystals for both controllers
will you please upload HEX files for both controllers
and i install it using Microchip Driver
is this correct or use some other method

Follow the next steps to make it work:


0. Build PCB
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:

...

Setting Vdd source to MPLAB ICD 2
...
Reading ICD Product ID

Running ICD Self Test
...

...
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

icd2 dead

you could try with an older version of MPLAB IDE. (7.xx)
it seems that some clones are not working with the newer versions of MPLAB.
