Re: KW 24 USB unknown device

Yes of course, I work perfectly fine with an IOW40 PCB, and never get warm.

Is it possible to change this product?

Re: KW 24 USB unknown device

Thanks for your answer,

It does not work in any computer.

I have changed the USB port and do all sort of changes and it does not work.

Besides, the chip seem to be hot when the PCB is connected.

I think it is damaged.

Re: Programing on LED-Matrix

Ok, I have told you before i´m not an expert on programing languages. I have experimented another code and i can switch on-off a single led: void CInterfaceSystemDlg::OnCHECK1writebit1() { // TODO: Add your control notification handler code here IOWKIT_SPECIAL_REPORT report; report.ReportID = 0x15; ...

Re: Programing on LED-Matrix

Ok thanks i understood, memset is not the "point" i need! Please can you give me an example (with C++ code) to set an individual led ON, on a matrix of 8X8? Actually i can do that, but using memset on this code: void CInterfaceSystemDlg::OnCHECK1writebit1() { // TODO: Add your control notification h...

Re: Calling IowKitGetSerialNumber!!

Ok, checked! More 2 questions: 1 - Is it possible to have special mode functions Led-Matrix and Switch-Matrix operating at the same time? 2 - I know the API dont have support for plug/unplug but is there a way to refresh or make the reset of the program instead we have to close it and re-open if we ...

Re: Calling IowKitGetSerialNumber!!

Hi again, Thanks Christoph, your advise to not use ioHandle several times along the program was very useful because i could save a lot of warnings from the compiler. :) The bad news are the assert failure doesn´t go away!! And i´ve tried with the 2 examples you have show, with the static text and th...

Re: Calling IowKitGetSerialNumber!!

Hi, first of all, thanks Christoph for your prompt reply! I´ve called IowKitOpenDevice() on the section //TODO add extra initialization code. I think this is enough or i must call the function several times as it comes necessary like in this situation? I´ve done copy/paste your code for my .cpp file...
