This premature screenshot shows an early version of the HMI Designer. The designer itself is quite simple, you use the menu/commands on top to create a “diagram” and the design tools at left will come up. In this case we create a HMI, but I will re-use the framework for other diagrams later. An HMI…
Voila – it’s not much to write home about, but it’s a Qt OpenGL app displaying 4 empty toolbar areas (colors for fun) and some 1000 symbols. The black area (left) will be the toolbar, the yellow at top will be common tools, red (right) will be property editor allowing editing of selected symbol. The…
Qt & Qt Creator have evolved over the years. I remember giving the tools a go some years ago and ditching them because they did not install & work properly. This is still the issue with some of the packages, so you need a bit of time & patience to get started on Qt. One…
One of the applications I want to create is a “HMI Designer”. This is technically very easy as I have done similar applications before. What I will do is to create a graphical application that can design square objects on a form. Each object will have a name that we can use for IO through…
I have been thinking a bit about creating a stand-alone HMI component. Basically a terminal with a touch display and optional keyboard, mouse and customized input equipment. The key principle would be that we use a Ethernet/RSX as bacbone for data traffic, while the HMI takes care of graphics, input etc. This is just some…
The latest version of the backbone bus. It is only 10cm long and with max 8 boards. Connectors are 2 x RSX, 5V PSU, and Actuator PSU’s. On the right side is jumpers and resistors for RS-485 terminator and bias. The backbone’s can be connected in many ways simply by connecting RSX1 to RSX1 and…
This picture is from CubeMX, just a few clicks and I have assigned 6 x UART’s, 3xSPI ports, crystal, SWD + added USB – the IO capabilities on the F405 never stop to amaze me + you gotta love CubeMX. Be a bit on your watch because not every possibility is available through CubeMX. Another…
I still got a few components to make\upgrade before I have a full Home Automation network. The CCM and RSX module allows me to create a central, but I need sensors and I need to feed the sensors power. One solution to this is to create an active RSX Switch with power output on each…
3D of a 3-port RS485 GW. This actually have 5 RS485 (or RS-X). 2 on the backbone bus running high speed, and 3 isolated with lower speeds in front. These can be used Standard RS485, RSX or even Profibus/485. The MCU is actually capable of running 3 port Profibus using UART’s saving the need for…
Added 2 coils on the 16 x Servo Module as well. On this I have plenty of space. I should have moved the MCU a bit down, but I will leave it for now. This module provide output only, meaning it can not do generic IO as my previous 32xServo/IO could. The limitator is the…
