BSA contains two techniques to model data. One is classic ER Diagrams and the second UML Class Diagrams. Class diagrams provide an object oriented approach that will go well with languages like C++, C# and Java, but a class is basically only a definition of a new datatype that you can declare as a variable…
It is two controls with an identical border on the picture above. The button display the border correctly, while the ComboBox do not display the border at all. It does have a BorderBrush that I set, but it has no effect. This is quite common with build in native controls – it might be a…
And this is the result of the code generator. In C++ and C# you can use inheritance – simply use a base class for symbols, autogenerate a HMIButton_base and then create the final HMIButton manually – this is a nice way to allow autogenerated code while you still have the full manual control. C# have…
This example is the property list for Button. This is just an early draft, but as I added more properties to Button yesteday I realized that this would take some time with the number of components involved as every property require a bi of coding. So using a CSV file allow me to use Excel…
I am sitting setting up all the properties for the components and it is a bit of work for each component, so what I want to do is one of my usual tricks to code using Excel. Simply by creating a CSV list, read it into a C# app and generate all the property settings…
Now as I know why I have a performance issue and know the solution it is also possible to make a compromize. I need to address performance, but I can live with what I have for a while. The issue is that it is easier to experiment with functionality using XAML, so I can make…
This picture is the old one that had performance problems. The new one is not so impressive yet, but it’s performance is far better. I ended up doing the exact same from code as I did from XAML finding out that it was far faster and allowed me to do some smarter code. At the…
This block diagram only illustrate a few of the modules in the Abstraction Layer – loads of more will be added as needed. I started this library years ago so it has existed in various versions, but are re-designing it to be cleaner now. This is a C++ library designed to make coding of user…
If you have ever written a driver or picked up someone elses code you will recognize the need for documentation and examples on how to use it. I am writing loads of drivers these days and stugle with Vendor datasheets as well as HAL’s – usually I end up hacking and trying to understanding how…
I typically code ESP32, ESP8285, a lot of STM32, Pico, Linux and Windows to mention a few, so I want to be able to move code between those platforms with a minimum of hazle. For this purpose I create a C++ API that I call “Abstraction Layer”. I did not want to use the word…
