Use problem

Post by sotomoko » Thu Oct 24, 2019 2:30 pm

Hello,
Sorry for my grammar but I'm French..

I am encountering a problem with InpOut32. I use this library with my program 32 bits on Windows 10 - 64 bits.
Before, I used WinIo on Windows 10 - 32 bits and I didn't any problems.

My program send values on the parallel port via a PCIe card. Some electronic material is connected and fed a dimmer. But, after replaçing Winio by InpOut32, I have some voltage variations very short and randomly.
For example, I have 6V output then I fall to 3V then 0V for half a second before going back to 6V.

I do not know what to do. Do you have any ideas or feedback from this type of problem?

thanks a lot for your help !

Sorry, I have no idea. As far as I knew, parallel port IO is binary either on (5v) or off (0v) so how you could possibly get 3v (or 6v) I don't know.
I suppose the 3v could be lag on your measurement device (meter?) but that's beyond me - and I have absolutely no idea why InpOut would be any different.

In any case, I didn't write InpOut (I only recompiled it to x64, I never claimed to understand everything about windows drivers) and I don't use it, nor support it anymore.

Sorry.
