Like some people among you I purchased some time ago the K8000 computer interface card, but not everyone still has the Visual Basic 4 environment or not everyone can simply write an application for external interface cards, I also had to understand this programming language first, so I started to build an application in Visual Basic 2005 Express Edition.Later I encountered some problems when testing and debugging the application and since I previously worked with ActionScript, Visual C # was a more understandable language, so I rewrote this demo version in Visual C# 2005.Some time ago Visual C # 2019 appeared and meanwhile the application has been updated to the newer version with a new application: the program assistant, which is a program that will help you to understand the programming language and which even generate the necessary application code, but still you have to paste manualy this generated code into your own application.You can download the application for free and you can rebuild it according to your needs.You can also download the assistant from here.Today I’m working on an ESP32 microcontroller, more about this later.If you have any questions, you can always contact me.Good luck!.K8000 computer interface card:K8000 C# versionsK8000 Demo C#K8000 assistantK8000 C# version 2010 K8000 assistant version C# 2015K8000 C# demo version 2015 multiK8000 C# demo version 2015
