I am sitting setting up all the properties for the components and it is a bit of work for each component, so what I want to do is one of my usual tricks to code using Excel. Simply by creating a CSV list, read it into a C# app and generate all the property settings…
This shows the moisture sensor from my previous entry with one exception – I added the USB Serial port. I have used various serial ports for debugging in the past, but never the USB despite I have always had it on my boards (almost always) – I simply never took the time to figure out…
This block diagram only illustrate a few of the modules in the Abstraction Layer – loads of more will be added as needed. I started this library years ago so it has existed in various versions, but are re-designing it to be cleaner now. This is a C++ library designed to make coding of user…
I typically code ESP32, ESP8285, a lot of STM32, Pico, Linux and Windows to mention a few, so I want to be able to move code between those platforms with a minimum of hazle. For this purpose I create a C++ API that I call “Abstraction Layer”. I did not want to use the word…
This is an error! in my wisdom I decided to always select a SPI Flash not realizing that CS signal mark the beginning and end of each command. nCS needs to be connected to a GPIO pin for SPI based memory to work.
double h = Height = newSize.Height; Height is a property with set and get functions in C#, so what I expected was that set Height was called first – which it does and then that get Height was called secondly – which it does not. In fact the assign operation will execute the…
This is a Dev kit from ST that is a complete Motor Controller in ESC format with 3 current sensors, 3 BEMF, 3 discrete Gate Drivers, Hall sensors, temperature sensors and 28V@120A Solution. The MOSFETS are rated at 120A with 480A pulse, but heat dissipation causes them to be limited to max 40A with hard…
St have a good series of MCU’s and I have stuck with F405 for a while. But, I just discovered G474RE, G484RE, G484CEm G491CE etc. This series is very similar to F405, but contains a lot of extras for a lower price. Also some of the MCU’s are LQFP48, but it is still a M4…
We will always have some kind of RTOS behind PScript regardless where we execute, so what I need a few system functions to interface to the RTOS in an uniform way. I my own linear scheduler that scale better than and that is perfect for extending thread shifters. The advantage is that I get the…
Part 6 introduces an easy way of communicating where one module raise an event and another receive it. But, for this to work I need some infrastructure that easyIPC provides for me. easyIPC uses a device address where device 0 is NMT (Network Master) on the local network. At this point I don’t care if…
