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…
I am working on “alDisplay” that is my embedded abstraction class to LCD/TFT diplays. This is quite a challenging task because I will have to deal with how specialized and proprietary these displays are and on top of that performance. The drawing above illustrate four layers – in my case actual hardware (orange) and three…
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…
