Hello Everyone, One person already got this problem but the final solution has not been given (if there is any). I recall : - my OS : Windows XP - my drivers :...
Well I had a similar pebolem, using XP however I was using K8.dll and had only 0 readings.Other than 150 ohm resistors that should be 100 ohm, and noticing ...
One more thought, check for shorts in the PC8591 area then check Vref, if it is low <5 volts it will take very little voltage to make the reading high. ... ...
Hello, My K8001 is not working anymore (led does not flash). I'm not sure what components are broken. the LED LD1 does not flash anymore. It might have been an...
Check for voltage on SCL and SDA first, should be 5v, if the 12 volts shot up any of the chips could be bad but a good test is the feel test, any warm or...
hello i've got a tip for buget k8000 users , disasemble a old printer , and plug out the stepper motors , there are 4 and 5 wired motors , connect them to the...
Hello, had a hard disk crash, so I had to buy a new one and reinstalled windows. today, I reinstalled the driverlinx portio driver, and winplc. if I run...
Hi Bart, I am working on the program on Visual Studio.NET using C# and VB.NET for a long time, and I have the same problem with you. For C#, I am using the...
Leong-Chiang Tee there is 1 difference: bart's software did work before his HD crash ... _________________________________________________________________...
... crash? oh well got it working again, changed the parallel port setting in the BIOS setup (from ECP+EPP to ECP only). it's wierd, because the communication...
... Yeah, thats true but be careful with the loads of the stepper motor... Use small ones without big loads (= big amount of mAmps...). I tried it with a small...
Hi, Well, the testing program provided by Velleman works fine. That is what I mean I may have the same problem with Bart. I tried to change the BIOS for the...
... A tip....USE TIP (hehheh). In other words, don't plug motors directly to k8000. Plug first some other components. TIP122 darlingtons are transistors that...

I just finished with my k8000; after that I start testing program from Velleman (output test) and LEDs started switching on and off. But my happiness hast take...
... Sure, a current amplifier is Highly recomended in this application. This TIP122 looks quite promising.... I ll try it ASAP.. Thanks for the info Jukka ...
Hi, After 4 months of hard work (hehe!), I've develop all K8000 library in Java. Of course, I have to use a low level library in order to access IO functions,...
... in Java. Of course, I have to use a low level library in order to access IO functions, but just with the minimum functionality (inpb and outb). Now, IŽll...
... Would be nice if you placed the lib in the files section of the k8000 yahoo group. http://groups.yahoo.com/group/k8000/files/ Makes it easier for futher...
Ok, I'm working right now (well, something like that...), but this afternoon, I'll put the library in that section. Just one question: Why there's ANYTHING...
I've already developed a Java JNI ready lib for the K8000 - look in the file area of this group. But if we can give up all the dll-stuff it would be much more...
*After that my k8000 is not responding any more. do you have an oscilloscope? check if you still have signals on the SCL/SDA lines! (should look like a...
I don't have oscillospcope. I checked a voltage between pin 8 and pin 16 and there is +5VDC, so PCF8574 gets correct electricity. I bought new PCF8574 (both),...
i am looking forward to the java driven k8000 , i also saw the java thing from guben , but it's not realy java ? its microsoft java ! , is this also the case...
No, no, no!!! Is SUN compliant java, all methods are developed in java, and just the low level functions inpb and outb (read and write from parallel port) are...
... Microsoft java? What's this? It's the C-dll with additional JNI stuff. JNI is not Microsoft. The only thing where Microsoft is involved, is the C++ IDE for...
... That means, that your solution depends on JNI two. So it's still platform depending. At least you need to recompile your dll on the respective platform....
Yes, you are right, I pull up functions. And I have to tell you thank you very much. A couple months ago I discover your JK8000 library and I based all my work...
Hi, I've solved my problem. In case anybody is on the same situation. I didn't figure out why Bart's API couldn't work on vb7 + windows xp. However, I...
