This demo is a bit in the early stage, but I am using C# and .NET 4.7.2 for a simple test. I developed in C# a few years back and was a bit dissapointed over performance. But, I notice that this have improved dramatically with later .NET versions so I am putting it up for…
This illustrates the BasicPI Firmware Stack in progress. What I always do in embedded applications is to make a “standard” main.cpp as follows: void AppInit() { // wire hardware } int main() { AppInit(); // start OS } A team I worked in years ago agreed on this standard so we should…
A common problem with plotting lines in raster graphics is visualization errors as we display the graphics. Most times we can just ignore these, but as I am drawing scrolling real-time plots I also receive the side effect of an integer error. This show a line that due to integer rounding is a straight line…
I have so far never seen a performance test where C/C++ did not win an easy victory due to it’s nature, but I am very curious about what I see in front of me now. The failure I pointed out earlier is how .NET or Windows behave then you push it to it’s limits, but…
I did a lot of work in C#/Forms a few years back and found it to be a bit to slow for actual usage. It was easy to get fancy UI graphics done, but you instantly started struggling with performance on the screen. I remember using ca 1 month to get the functionality done and…
This is an early beta of the HMI Designer. The idea is that you draw your HMI displays, save them as XML and then send them to a HMI Browser. The Browser will execute the graphics and send back user events allowing a system with no knowledge of HMI, how or what to make use…
This diagram illustrate the HMI solution the way I am planning it. I would like one external RS485/UART so I can attach the display to any embedded solution. CAN, USB and SPI Backbone is mandatory. And I think SPI Half Duplex will do fine over max ca 50cm that we talk about here. SPI is…
I want to work on creating a modular HMI solution. I already have Raspberry PI with HDMI, Keyboard and Mouse interface, but I need a solution for smaller displays, specialized button’s and knobs to go on instrument type projects. The concept I like is that an embedded device can store it’s own interface and then…
