[SOLVED] Project to replace CY7C64613 in the ICD2

[szlovak]

Hello

I tried to print circuit (these from pdf files for ICD2 , DIL sockets) but it isn't precisly made. Or I'm setting something wrong in acrobat reader. But I think none of the available settings is making exact printout . The difference is about 1mm more than it should be in DIL 40 socket. Do you have the same issue?

I printed file you mentioned and it has exactly correct scaling.
Check to make sure Scaling option in Print dialog set to NONE

I've tried it on HP LaserJet IIIp and 4L wit h the same result. Now I'm making new pcb in Eagle

I am using LaserJet 4L as well, I don't see problem.

Hi szlovak
Have you ever done a calibration print on your printers from a doc
created by yourself?

This often highlights printing problem source in different systems.

curious ...... Polymath

icd2 with Pic16F877a+Pic18F4550+Firmware work ok

I read your schematic Icd2_Usb_4550 about the ICD2 clone but I can't understand some details. The lines connected to pins 2, 3, 4, 5, 7, 33, 34, 35, 38, 39, 16, 10 of 18F4550 and to pins 25, 26 of 16F877A that go into the bus are unlabelled! Where do I have to connect them?? Waiting for your answer, thanks a lot!!

hi , this line not go anywhere.
just take a look at the pcb and you will see that.

Hi NICK7, It's a nice job!

I'm unable to find the schematics, pcb and other info about this icd2 clone. There're too much pages in the post and i'm not sure if i downloaded the correct files.

Is the circuit completed? can anybody tell me where it's?

thx.

Like i was told and quite rightly to lot's of people have worked very hard in bringing this icd2 clone to the world.
Read the thread from the start and study the last few pages and you will find all the info to build a working ICD2 clone PIC's has done one so as Andy123 has done one i have designed my own but not tested yet has i'm busy and my work is taking over my life at the moment and waiting to palce bulk order for some of the parts but no doubt once i have built it and it does not work i'm sure i will get all teh help i need to get it working

My advise is study and build any one and see how you get on after all you can remove the compenents and re-use them

hehe i done that... i found almost all I need.

thank u.

Hi
Here is my latest modification. I've added an another ISP connector, which is dedicated for programming only. Their PGD, PGD and Vpp/MCLR(selectable using jumper X4) pins are in high impedance when the VPP signal isn't active. So you can use those pins in your target circuit practically without any limitation.

Attachment removed. You can find the latest schematic and pcb here:

Hello all,

What are the intensity / amperage requirements for Vpp ?

Few mA only.

MAX662A is a good one, but it's relativiously expensive, try TPS6734 from ti !

I have used MAX641. No external mosfet or diode necessary ( up 250mW output )
Only 1 inductor (470 uH) and 2 resistors for adjustable out.

Hi,

May you upload your schematic ?!

I'm having some trouble getting the comp to recognize my circuit as an ICD2. I connect it to the computer and this is the output of usbmon

000000: PnP Event: Device Connected (UP), 21.06.2006 22:15:15.8593750
The USB device has just been connected to the system.

I'm using PiCS schematic and firmware (rev B) and I have the all of the 4550 and 877A hooked up correctly (ive checked like 5 times). Is there anything special I have to do when I burn either of the chips?

Thanks

The schematic in my previous post was wrong. Now it is fixed.

 

[chupos]

First I'd like to thank everyone who has contributed to this project.
But I got a small (or huge) problem. I've built it now on a breadboard, windows detects the 4550 correctly, installs the microchip drivers, but when I tell MPLAB to connect, I hear the windows sound of "usb device disconnected", then again the "connected" sound, and then MPLAB says:
Connecting to MPLAB ICD 2
ICD0289: Unable to re-program ICD2 USB OS firmware.
ICD0021: Unable to connect with MPLAB ICD 2
MPLAB ICD 2 Ready


Other times it just says "connecting" all the time and never connects. No idea of whats going on... :'(



any idea?
thanks in advance,
Alex

no need resistor for mclr to +Vcc

why exactly? MCLR pin is enabled when I look into configuration words

Re: Target connector pinout

Need some clarification, because I am getting confused based on the response I have:

Based on the information I have:
Target PIC RJ connector pinout is:

On the ICD2 itself:

1-
2- PGC
3- PGD
4- GND
5- VDD
6- VPP

The external target board has the opposite pinout:

1- VPP
2- VDD
3- GND
4- PGD
5- PGC

6 pind cable is crossed.

IS THIS CORRECT?
If yes, why every schematics I saw has ICD2 connector exactly as target board?

Look at the picture from Microchip:
is this ICD2 connector or an external target board connector?

I am really confused...
Anyone with real ICD2 can confirm pinout of ICD2 itself..


Thanks

I think it's flipped, at the end of this site is explainedhttp://www.embedinc.com/picprg/icsp.htm so the PCB is f**ked up and 1-1..6-6 cable is required
