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…
I managed to get STM32H743 running blinking some leds, but not without pain. STCubeIDE is able to download code, but fail on debugging. All in All I basically conclude that H7 is not sufficiently mature yet! This is not about the MCU, but tool, toolchain, drivers and everything around it.
Well – I got a STM32H743 Nucleo kit yesterday and wanted to autogenerate code for it from CubeMX (or STCubeIDE more exctly) – out of the box – it generates code that DOES NOT COMPILE on an eval kit. Sadly this is not the first time, it has become more the rule than the exception.…
I decided to have a look at the STM32H7x3 series running at 480Mhz. The Nucleo board uses the 144 pin ZI version, but they also have a 100 pin V version. 100 pin is attractive because it gives me access to external memory, Ethernet and more + if I should go for a 100 pin…
