Hy all
I installed the IC upside down and now I’m missing a new backorder but my PIC.
Where can I get the PIC to my IC to flash?
Thank you
Sorry, for copyright reasons we never supply source code.
You can return your assumed defective PIC for inspection/replacement to:
Velleman Projects Tech. Dept.
Legen Heriweg 33
9890 Gavere
Belgium
Can you send me a new one?
i Paid more for shipping then a new one 
Send me a Facture for Pay IC an shipping
Best regards Alf
Sorry, we do not sell direct.
In that case, please turn to your Velleman distributor.
Order code: VK8090
I have this same problem, I cant find kit VK8090 anywhere on google where can i get a replacement pic? or the binary to download, I have a pic programmer and it looks like you pinned out the programming port.
The K8090 protocol is well documented.
The Microchip PIC18F14K50 is well documented as well.
What is missing?
The binary.
No, it is not.
It may look difficult at first, but just think of the Open8055 project. It is not impossible to write compatible or even improved firmware for these cards. Velleman has excellent electronics engineers. These Velleman projects are very solidly engineered products. However, I think they don’t develop the PIC firmware themselves. If I am not mistaken that is done by some small subcontractor and it is the reason why they cannot publish the code. They probably should (develop and publish), but that is an entirely different discussion, which should not happen in this thread.
James Holland and I created a PIC18F based replacement firmware for the K8055. We unfortunately haven’t seen James on this board since. Nevertheless, the firmware, client library and first example programs are published on github. I am pushing little enhancements or bug fixes every week. The firmware has capabilities, like servo control and frequency counting, that even the new K8055N doesn’t have.
I don’t own a K8090 and I don’t intend to order one tomorrow. But I think I have a good grasp on how a USB based Microchip PIC firmware and the corresponding DLLs work. The PIC18F14K50 can’t be that different from a PIC18F24K50, which is my favorite chip so far. I use it on the K8055 and K8055N boards. I think there is a lot that you could copy from our code.
Here is your problem: If all you want is a binary, then I can’t help you.
If you want to start something like an Open8090 project, I can and will help you.
For the record: we do write our own PIC firmware.
Protecting the firmware is our only weapon against illegal copying of our projects by (Far East) kit manufacturers, as all other parts are freely available…
I stand corrected then. I was under the impression that was part of the cooperation with RE-Applications.
RE-applications wrote PC software in past, I believe it was for the PIC programmer.
If you think about it.
If Velleman did put their firmware out for everone they would not be in bussiness very long and unable to bring out more cool products.
If you read through past post that have always gone out of their way to help.
They have rewritten some of their software for those that have requested it or swapped out PIC chips for those that have damaged them.
One of the things I don’t understand are the ones that say it cost to much to send the PIC in for trade out.
Sending the PIC in would be more cost effective then buying a new kit.
Just my thoughts.
Stepping off of my soap box.
I agree with most of your points, Wrong Way. Velleman is a rare exception when it comes to support for their projects and kits. Velleman staff here on the forum is outstanding.
That is the one point I disagree with.
Protecting their firmware is entirely Velleman’s prerogative. And it may be a good weapon against Far East rip offs.
However, that isn’t their only weapon. Their kits are outstanding in build quality as well, and most of them are targeted at the beginner to intermediate level hobbyist. You know very well that some beginners can even damage Velleman type PCBs. I know you know this because you are one of the usual suspects asking for pictures and trying to help figure out assembly problems. We have seen pictures of damaged traces. We both know that this should never happen with the type of PCB, shipped by Velleman. But it does happen.
You therefore know what would happen if one of those beginners would lay their hands on a Chinese manufactured PCB. They would melt the traces and destroy the PCB beyond repair during the first 15 seconds of working on the project. Correcting a mistake by desoldering and remounting the component is next to impossible with that sort of low grade PCB.
Show me a Far East rip off that can beat Velleman quality.
MostlyHarmaless,
When you look at it from that aspect you are right.
so, stuff that should be moved out of this thread aside, what can I do? Like I said I would be happy to buy a replacement pic as it was my fault that it broke, but I cannot find the VK8090 kit anywhere, I would be happy to send in my pic for a replacement but I broke it, will you guys replace it?

I get paid very well to program microcontrollers, ones far more powerful and complected than pics. If you to pay me to write that code I will be happy to earn some extra money on the side, but after coming home from a long day of programming I want to sit down, do some simple soldering and play with a toy, not program it.
FIRST: contact the shop where you bought the kit. They can order a replacement PIC at Velleman.
If the store is unable to help, you can call your local support office: (817) 284 77 85
