Many solutions depend on something happening as a responce to time – it can be something you need to do 12 a clock Wednesday or every second, but to do so you need a timer object that can generate a signal on the requested time. This tool is needed in all diagrams in BSA for…
The table below shows the current list of tools in HMI Designer part of BSA. It is few common tools like lines, notes etc not listed here, but this is the basic collection. I might add a few tools as I see the need, but this will more or less be version 1.0. A main…
This table shows the planned BSA support. Windows, Raspberry PI and STM32 are primary development targets, but Linux is covered through Raspberry PI and Mac’s will be covered. Other platforms, specially on the BSP (Board Support Package) side will be added. Platform BSA Designer HMI Browser BSP Windows Yes Yes Yes Linux Yes Yes Yes…
DataGrid and PropertyEditor is still work in progress, but the same PropertyEditor that is used in BSA will also be available as a component. The same goes to the DataGrid. DataGrid is a smaller grid designed to use inline edit. I will also use a virtual grid designed to visualize huge amounts of data. I…
This is the beginning of BSA’s property editor. A property editor is a specialized grid that can edit objects and is very common in dveloper tools. Rather than produsing hundreds of IO diialogs you use a generic editor that you pass a list of variables. The way this will work is that it show the…
This first picture show a UML State Diagram. I promissed to focus on HMI, but I fancied adding the symbols before I hide these diagrams in the first version. This second picture show a Plain Logic Diagram. I will walk through the interaction between the diagrams and their usage later. As you can see it…
Qt/QML lack an image designer, but I found that using good, old MSPaint worked out well. I have added tools to support various modeling techniques, but will focus on HMI design and automation in this first version. It is a graphical GUI designer included in Qt, but good luck getting something out of that. This…
I like to think about an input signal in the four steps autlined above: 1 – Signal is collected (or received) in raw format. typically sampled on a digital or adc pin in raw format. A 12 bit ADC will have a raw value between 0 to 0xFFFF. 2 – A raw value is of…
This figure show a key principle in modern HMI design. I have only illustrated 2 input signals, but the principle is the same regardless of what signal or what hardware you use. Using a analogue signal as an example you collect that from a sensor or ADC channel. The signal will then be normalized and…
My previous entry talked about coding in QML. I am still on the learning path here, but I am slowly finding my way into QML. It is a steep learning curve, but once you start master the technology it also get easier and the graphical result is the best I have seen so far. It…
