Many modern applications use custom theme/styles, but this is actually far more difficult to implement than you would expect on Windows. Windows have a lot of standard GUI components where you can control most, but not all colors and styles. So, if you want dark theme you either need to buy a library or start…
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…
Some of you will remember that I planned a “System Diagram” in Plain! That was a block of configuration code that tied event on modules together. This is exactly what I plan to use UML State Diagrams for. In this diagram we generate a Temp Changed event on one device that is sent to a…
Just showing a rude alpha version of the designer – I have yet to settle for a name I like. Notice the scroll bars on the diagram. Modifying Windows Scrollbar to dark theme is actually a bit of work. Windows Controls always leave out a few bits you can’t control per application, so getting a…
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 the big advantages with STM32 is that they have a range of MCU’s from the small M0 series to the more powerfully M7 series. Changing MCU to scale up/down is very easy. The MCU’s will have some differences in pin usage and register usage, but ST have been decently good at keeping their…
This has been on my list of things to do for a while and represent a few challenges. Chips like AD9851 contains a full DDS that interface to a MCU on one side and give 3.3V signals on the other side. I have yet to decide wherever to use AD9851 or something else, butAD9851 is…
2nd Draft of my new 32xServo/IO Hat rev 1.4. Added the leds and missing SPI resistors + reorganized connectors at bottom. I notice that I need to add a capacitor to assist D2 (TVS) on the bottom + I want to add 2 jumpers allowing left and/or right array to be connected to 5V as…
