jdm programmer schematic

Hi,
does anyone have schematics for a pic18f4550 programmer?
 

jdm programmer 18f4550

Have a look at this page (programming software and schematic for hardware):

You can use JDM programmer + winpic800 software. This combination works fine for me.

Do you think this will work?
I can't see the 18f4550 listed on his webpage but there are several other 18f chips listed. (**broken link removed**)

jdm 18f4550

Zanor I think this will work because as you can read this is JDM based programmer. Do not worry, this should work with winpic 800 even 18F4550 is not listed on programmer website. Supported devices depends of software and winpic 800 supports 4550.
 

pic18 programmer schematic

predrage, I am using the Olimex JDM pg2c and WinPic800 and I can't quite get my 18f4550 to program. I've never used this particular PIC before nor have I used this software so please advise me what I might be missing. I just used this JDM to program an 877a using ICPROG so my hardware is correct... I bet i'm missing a setting in winpic800. Is "blockade configuration" ok to use? I'm borrowing this JDM... I use the real icd2 at work so I'm not very familiar with this thing. Did you have to change any special settings? I'm writing certain data but reading back FFFF's. Even after an erase I read back mostly FFFF's but some other data is still there. :cry:

I should also note that it detects my device as UNKNOWN.
 

jdm programmer pic18f4550

VoltageDrop, you could uncheck 'blockade configuration' and use the test feature to check your JDM (Vdd, Vpp in programming mode). PIC16F877A has a little lower Vpp threshold than that of PIC18F4550, so your JDM may not work with 18F4550 while it works with 16F877A. JDM configuration of WinPic800 is exactly for this Olimex PG2C, you don't need to change any thing in WinPic800. Also, try to put a small cap (47pF or so) between the RB6/PGC pin of the 18F4550 and the ground as close the chip as possible.

Cheers,

i need simple programmer circuit for PIC18F4550. it seems costly for me to buy the programmer. So i need selfmade kit.

Thanks & Regards.

Bootloader for PIC18F4550 is the simplest for U, search with google . . . . many and many . . . . .

You can program it using ICD2.
 

pic18f4550 bootloader

For PIC18F4550, you can make an DEV for it. With this board you can using bootloader firmware for 18f4550 to program it via USB port (that cool!) and you can write code and test some usb project on this board.
All of them (schematic, firmware, soft PC) you can download from www.micochip.com
keyword: 18f4550 + bootloader

Using JDM with winpic800, you can program hex file for 18f4550...
For any thing you can contact me: linhnc308@yahoo.com

Has anybody decoded the PICSTART programmer?
 

multi pic programmer 5 ver.2

As the title says, I'm using the Multi PIC programmer 5 v2. Trying to program a PIC18F4550. I am using Win PIC, and I get the following:

ERROR: Programming FAILED !

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

JDMs are not very reliable. Try programming a stock 628a first.

I don't have a 628a, it did work on the 877A though if that helps any...

Edit: I also tried this with a few programs (winpic, winpic800,PicProg4U--which didn't support it)...etc.

What did everyone else use for their 4550's? I was looking for the simplest way to program it for my ICD2 clone.
 

how to design a multi pic programmer board

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.
