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…
I just received HLP-7688A module and looking at the size I must admit that I tempted to create a Switch/Router in Hat format. I am not os sure about the SPI on this, but it has 2 UART’s, so assuming I can control the code on the Linux module this could be interesting with Wifi…
I am slowly getting the SW stack for BasicPI together and wonder if I should implement a minimal shell language based on Plain. I can regardless run a Plain appliction at start-up for configuration, but a shell language means that we are able to connect on a CLI console and write/execute scripts and commands ad-hoc…
