UML is a well accepted standard for modeling complex software solutions, but it has never reached executable accuracy. The standard lack a technique that allow executable logic, which is exactly what PLD does. This is key to having a tool with 1:1 between diagrams and code. I started modeling with Entity-Relationship Diagrams years ago, and…
This costed me ca 400.- USD on a local shop, so I decided to try it out. The first thing is the visual look. FlashForge Finder 2 looks like a furniture and can easily be placed in a living room or office. One negative issue is the manual – it’s a bit short and it…
UML State Diagram is a standard, but I find it’s implementation into tools to be wage. So, I implement my own adaption because I intend to have a 1:1 with actual source code. This is not uncommon as most automation tools will have to make adaption in areas where executable accuracy is weak. I was…
Just showing a test diagram on the UML State Engine Designer I am making. It is stoll lots of work and details left, but progress is actually going fast the days I work on it. As for now this is just an experiment. A state engine can visualize some top level flow, but the details…
One of many new features that was not available in Target 3001 is display of signal names on tracks and pads. I selected the wrong footprint for SWD, but as it is the same size as a 1.27 pitch header I did not think it matter before I noticed that it count the pin differently…
It is soon 1.jan.2020 and Norwegian import rules changes, meaning I basically get MVA and a 20.-USD handling fee on every package unless I get the foreign company to declare MVA. It will be a pain and take some time before this happens. Ordering parts from Asia will be close to impossible unless you order…
I am a bit handicapped as my Lamp with a magnifier broke. I was using that all the time, but having seen how badly designed that it I decided to rebuild both of my lamps to be LED lamps. What I will do is to buy a 130VAC to 12VDC adapter in a shop (or…
Plain (Programming Language for AI Networks) is very different from Languages like Python, Java and C#. The only similarity is that they all are based on a Virtual Machine and all use C/C++ as native host language. One difference is that C++ is more openly integrated into Plain than Java and C#, while Python have…
I decided that I want to make 2 different Ethernet/Wifi modules With different purpose. With Raspberry PI it will be 3, but RPI and ESP32 overlap in functionality. ESP32 with Ethernet/Wifi/Bluetooth is a very attractive “Connector” solution where I can add more connections by adding multiple Hat’s. I can sadly only add a single Raspberry…
I recently purchased an small dev kit for HLK-7688A (above) and noticed that it has a Prolific USB-to-Serial port. Connecting it I get this message: Windows detects the port, but the driver will not open it. I assume this is a fake chip issue again. I have had this issue with Prolific before – which…
