Thank you

Here is an updated link to the K8055D.DLL source code: box.net/shared/dqjnhtjb2t
This source is for the original version (dated June 2003)

Thank you so much ! :smiley:

To expand the capability on my board I replaced the OTP processor with a FLASH processor loaded with the Microchip USB stack and bootloader, then I was able to develop firmware using the Virtual Com Port implementation and to modify the code via the USB port using Microchips demo application.
Its a bit more involved than using the Velleman firmware but not beyond someone with a little Microchip programming experience. At the moment I’m working on firmware for the WinUSB driver.

This link now redirects to an online backup website, is the DLL source still available elsewhere?

I re-open this post.

I’m trying to use the K8055 interface with my Raspberry Pi 3 using Windows 10 IOT.
Is it possible to to have a compiled dll (k8055.dll) for this device ?
The raspberry is a arm processor and don’t work with usual k8055*.dll

Thanks in advance for your help.

Have fun with the K8055 Usb Card on the Raspberry Pi 3 (model B)

Sorry for reviving a very old thread, but I am having trouble downloading the source from box.net.

The link still seems to be active, but nothing happens when I click download. I have tried Edge, Chrome, Firefox and none of them are able to download.

Does anyone have a copy of the K8055 dll source code? Thanks!
