hi there i want to design interface board such as k8055.but with Different options.
it is can programm it by bv6 or c++ or any language same k8055 issue. and i know it is easy but the Difficult one is new dll file for it.so how can i creat dll or do dll file which can allow anyone to put it in his system32.and doing program by any language???
You think creating a DLL is the difficult part? I guess you haven’t worked on the firmware yet.
Please use proper punctuation in your posts. Apart from the language barrier, without capital letters and punctuation marks it even harder to make out what you are trying to say.
We can obviously not teach you how to write a DLL.
so i can creat dll by firmware? it is help me?

ok

but why?
you can give me the key and i can find out the way. i need your Suggestion.

Did you ever take a look at the Open8055 source code?
It’s all there. And it is all based on free, open source tools, like the MinGW compiler and the Lite version of Microchip’s C18. There you have a “working” example of creating a firmware together with the corresponding DLL and a test application.

mr MostlyHarmless i thinking you have good Experienced.so can you show me or do what is you say by attchment file or vedio.
thanks dear

I don’t think this can be properly explained in a YouTube style video.
Just check out the source code here: github.com/wieck/open8055

i understand dear
thank you
i want ask about 3d printer when is it come?and i can run it under mac system?

thanks about your feedback me.i hope these github.com/wieck/open8055 help me.any way i dwonloaded and i read it
so please do not maind if i want to ask you.
thank you dear
i want ask about if i want to change pic16c745 by new on is there any procedure i have to do it befor install it?
Yes. If you want to exchange the PIC I would recommend that you use a PIC18F25K50. In that case all you really need to do is to remove resistor R35. On the original K8055 board, that resistor is forcing USB into low speed mode and we definitely want to use full speed USB. The PIC18F25K50 can operate full speed USB on its internal oscillator. The Open8055 firmware when compiled for that PIC does not use the external crystal at all. I can remove the crystal and the board functions just fine without it.
If you want to use any other PIC, like the PIC18F2550, you also need to replace the crystal with a 4MHz one and the capacitors C4 and C5 with 33pF. Those older PICs are not stable enough to operate full speed USB on their internal oscillators. They do it for a while, but not reliable.
Finally (most important) you need a way to get the Open8055 firmware or the bootloader into that PIC. I use an Olimex PicKIT-3 clone to do that. Note that many older programmers do not support the “K” series PICs. So if you have a programmer already, make sure that the chip you’re getting is supported. If you don’t have one, just get a PicKIT-3. It is a USB device based on a PIC itself. The MicroChip IDE recognizes it and flashes the programmer as needed. You can basically compile from the IDE right into the PIC, if it has an ICSP on the board, like the K8055N does.
you are charming me.
but i want to change by same model pic16c745.
thanks

thanks[/quote]
Why in the world would you want to use such an outdated and obsolete PIC in a new design?
actually i want to replace the pic16c745 which in k8055 by same new model.
that is it.

Do you have the firmware needed to load into a pic16c745 to run in a k8055?
no. i do not have any thing just k8055 board and new pic16c745
That is a dead end.
For copyright reasons, Velleman never publishes the code or even .HEX files of the firmware for PICs. You will NOT get anything that you can load into that “new” PIC16C745, that makes it work like the original one that came with the K8055.

My goodness.so is there any Solutions???or idea???
