BSA – Data Flow

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…

BSA – Styling Native Controls

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…

BSA – Code Generator Results

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…

Home Autiomation – LoRa based Bootloader

Making one is straight forward, but I actually think I can use the build.in silicon bootloader as is… You probably know that all STM32 MCU’s comes with a build-in bootloader in ROM located at a special address. You invoke this…

USB – Serial Debugger

This shows the moisture sensor from my previous entry with one exception – I added the USB Serial port. I have used various serial ports for debugging in the past, but never the USB despite I have always had it on my boards (almost always) – I simply never took the time to figure out…

Home Automation – Moisture Sensor

It’s spring and summer comping up, and I am spending a bit of money on flowers every year so I would like to know more accurately their condition. Weather can change from very hot to very wet and not all plants get what they need from rain – some plants also get to much water…
