Need Help for programming a PIC18F2550

Hello everybody,

I don't know if I'm at the right place for that question, but surely someone can help me. I'm unable to program a PIC18F2550. I have a JDM programmer, a willemprog and I also build a Tait like programmer but none of them can program thoses chips. I've tried WinPic and WinPic800 (cause IC-Prog does not support 18F2550) but always no result. I'm able to program many PIC like 16F84, 16F627, 16F877 and some others but not the 18F2550. I've looked at the data sheet and the programming specs but I didn't see nothing special. They seems to support standard programming and ICSP too. If somebody have already program thoses chip please tell me how you did that!

Thank you for any help

I guess it's the time for you to get a real programmer. EPIC, ICD-2, PicStart or else. Yup much expensive but sometimes you don't have better choice.
