A lot of IoT/Cloud solutions focus on access through internet, while I want a closed network of sensors in my house with a switch that enable very secure and restricted access from outside that network. I don’t want it to be fysical possible to break in without fysical access. But, I want to use Wifi…
I have always dreamed about automating my own home and one of the key starting components are low cost sensors. This technology is available today, so it is not rocket science, but I want to create a low cost practical system. Starting with sensors only I would like to monitor temperature in every room in…
I recently bought a test kit (ESC) from ST that I used 2 days on to create a motor controller, and I liked the design so I am using it as template for a new controller. You will remember that I created a “ThunderStick” using DRV8301, basically a controller very close to the Vedder design.…
I have used STM32F405RG for a long time, but decided to switch to STM32G series and upgrade some of my PLC modules. This shows STM32G491RE simply because I managed to buy a series of these. These are more capable than the F4 with upgraded IO + 2 FD CAN ports. I have earlier used SPI…
This is the Diagnostics Tools in Visual Studio showing BSA Start-Up. The first big raise of memory usage is probably my Tool View – not sure – but the last one is me moving BSA to the other screen and redrawing the grid in the process. This is the cost – something like 50Mb or…
Following my previous article I realized that creating and adding UIelements are the issue. I have those in 2 places – once as I create/modify the grid and secondly as I create a list of UIelements for the Property Editor. In both cases I create a load of controls using new and maximize IO between…
Loading the attribute list into the property editor was a performance surprice – it is slow and noticeable at already ca 10 attributes. I am fully aware that IO between CPU and GPU is a weak point in performance using GPU technology, but this one is rediculous. I started having similar problems on QML with…
The table above looks ok – you can see an array of attributes as expected. The picture below is the same list with attribute details expanded. It’s a bit work in progress, and I am not sure about the result yet – I have to think about this one as it looks a bit messy.…
This is my first attempt on a mock up of an array of attributes for UML Class, and I am very pleased with the result. I need to change the header color of the table and do a few things, but this was a first mock-up to get a feeling about how functional this would…
I will introduce a display symbol to do IO towards HMI so I don’t need copies of Forms everythere, but the diagram below is actually functional. I could actually generate code based on this – the two processes are modules where one run on STM32 and the second on Raspberry PI. The first collect ADC…
