That's exactly why I'm making one. However I'm making the USB one and I need the 4550 first!

Cheers,
Spork

Also, happy St. Patrick's Day everyone.

I used this JDM to program my ICD2 (16f877A and 18f4550) along with software WinPic800 and works OK.

All the diodes (ecepcion zeners) are 1n4148
Transistors are 2n2222

Thanks! I'll build that, and see if I can't get it to work. So far I've got the origional JDM, the Multi PIC, and I can't seem to get the 4550 working. Can you tell me which pins go to the ground, dtr, rts, etc.?

Hi

View the 2K2 resistor is in the rs232 side. Other are in the pcb side.

I have made a board for that simple programmer, can someone tell me if it is good?

Though the board could easily be squeezed to a much smaller size, however, technically its alright layout.
You could go ahead with it.

I etch my own board, so price won't be a factor in the size. Also, I just wanted to make sure everything would fit comfortably with as few jumpers as possible. Thank you for the input, I will keep that in mind when making boards in the future.

Great Job, this work ok.

With the JDM... Are there any special options I need to check for the 18F4550 in winPIC? Or does someone have another program I could try with?

EDIT: I have tried winpic, winpic800, icprog, picprog4u (didn't have 4550) on default settings, none of these worked. Please help!

Greetings,
I programmed a 4550 with JDM and Winpic and had the same problem. On the "Interface" tab of Winpic, Put a tic in the box for "slow mode" and set the Interface Type to "COM84 programmer for serial port." That's what got it to work for me. Also, make sure Winpic is set to the correct COM port. (On my system, it is COM3. Yours may be different)

I also built this programmer:
ht*p://www.sprut.de/electronic/pic/projekte/brenner8/index.htm#aufbau
I built rev 2. The current version is rev 4. The site is in German, but fairly easy to navigate (I speak only English). Excellent USB programmer, all free (including firmware), but uses only their software.

Hope this helps,

Also, the programmer DID work for my PIC16F877A and I made an adapter (socket missing pins 23-25) for the 4550 as well, and still had no luck.

Edit: To clarify, I got the adapter from the creator at hxxp://www.hamradioindia.org/forums/viewtopic.php?t=468 and

Edit2: From the error, It looks like it doesn't write anything to the chip. This makes me thing that maybe the MCLR is too low? Any ideas?

Thanks,
Spork

use ICSP pogramming... but only use 18F4550 porgramming pins... so 18F4550 Programming succeeded... i made it...

jdm for 4550

Yes.. ICSP lets you program almost all PICs

Spork · Mar 27, 2007

picprog4u, pic18f

Thank you all for the replies, I will do some testing right now. I am using ICSP with this:

Vpp-1____Vss-31
Vss-8____Vdd-32
Vdd-11___Clk-39
Vss-12___Data-40

I was told that is the correct connections for 40 pin?

Here's a link to my sites Quick project guide, it can be used with any ICD type programmer. Schematics and source code for a few popular PICs included plus a quick MPLAB tutorial. The 40pin 16F877A is included.

I tried it with no luck. Think it could be a problem with my serial port? This is really annoying. All 3 programmers I have made work just fine with the 877A..

I have tried: Default settings (JDM + 4550 configuration without changing options), setting VPP first option, "slow" to make sure it wasn't a timing issue, tried erasing and reading, etc.

The 4550 always shows all 0's, and I'm fairly sure that the erase and verify are working fine. I think it is just writing that is failing.

I don't know what I should try next, any sugestions?

EDIT: Blueroom, I may make an inchworm. I gues lazyness just leads to more work...

Computerman29 · Mar 29, 2007

parallel multi pic programmer

Maybe it is write-protected? Check config settings in Winpic.

Also, try putting a tic in the box for "Vpp +13v" on the left side of the interface tab of Winpic. I know that the 18F series is Vpp=+12v, but sometimes even with my USB programmer I have to set it to +13v for it to program properly.

Also, does it say "Set Interface Type OK" about halfway down on the right side of the interface tab of Winpic? If it doesn't then there is a problem with your serial port. Maybe Winpic is set to wrong com port.

Or, some serial ports just can't supply enough power for JDM - especially the newer ones and laptops. . Try on an older system? Maybe try a parallel-port powered Programmer?

One more suggestion: After you get your ICD2 working (or in my case, a Brenner8), THROW THAT JDM POS AS FAR AS YOU CAN IN ANY DIRECTION AND FORGET ABOUT IT!!!!!!!! That's what I did.

HI..
Sorry, I could not respond before.
1. – Use my diagram:

2. – Use Winpic800 and selects hardware JDM and you port COM1 or COM3:

3. - Reduces to the minimum the length of the cable between the JDM and the PIC. (This is the error that surely you have)

4. – Connect
VDD 11 AND 32
VSS 12 AND 31
VPP 1
RB7 40
RB6 39

I will build your design tomorrow with the short lengths, hopefully that will work.

Thank you for the feedback.
