I have a problem with a K8055 (green board with P8055-1 number on it) board. The board is a part of a bigger projekt and is not recognized by the computer any more.
The programming is very old and the source code is gone. I need to replace the broken board without touching the programming.
My questions are now:
Is the programming really 100% NOT ON THE BOARD and only on the computer, so that I can just replace the board (with the right jumper positions)?
[quote]2) Is the newer version (velleman.eu/products/view/?id=404880) 100% compatible with the older board (K8055)?[/quote]Yes, except the PWM frequency is 46.875kHz instead of 23.43kHz of the K8055.

It should be possible to use your original software.
thank you for the answer. Regarding to my first question:
Is the programming/software really only stored on the computer and not on the board?
I´m asking, because on some boards (Arduino and so on) you have to put the generated code onto the board (with a “upload code to board software”) and the code/programming/software is NOT stored only on the computer.
[quote]1) Is the programming/software really only stored on the computer and not on the board?[/quote]Yes, the application software is completely on the computer.
This should be the approriate thread to post my question: Existing software does not recognize a new K8055N board.
My customer works with an old version of the USB Bord experimental board in his plant. In order to rework the associated software we are using a contemporary K8055N. The existing software worked with the K8055N, only after replacing K8055D.dll with Version 5.0 from your website. The original K8055D.dll didn’t have a visible version number. It’s 338 kb in size and dates from July 1 2003, though. Now, we need to avoid different behaving software versions. A testing environment that makes any sense should behave the same way, the productive does, shouln’t it?
Now my questions are:
· The compatibilty statement seems not to apply to K8055N - or what could we have done wrong?
· Is there a documentation of version differences?
· Will the old board run with the new dll?
· If no: Is there a simple way to update the microcontroller firmware on the board
to the current version in order to make the old board run with Version 5.0 of K8055D.dll?
[quote]• Is there a documentation of version differences [/quote]The PWM frequency is different in the K8055N compared to the K8055.
K8055N: 46.875kHz
K8055: 23.43kHz viewtopic.php?f=3&t=10295
[quote]• Will the old board run with the new dll?[/quote] Yes, you can use the new DLL for the old K8055 too.
