PScript would only be able to perform math unless we integrate it to the target platform. In the drawing above I illustrate (1) the build in function “print” and (2) a variable “a”. Both are declared as a C/C++ struct in a table that point to a function with a specific format that accept a…
I must admit that PScript is a nice break from the larger BSA task. Sadly BSA is written in C# and PScript in C++ because PScript is perfect for extending BSA. But, I can actually use C++ from C#, so lets see. I have created a stack that I use while I interpret and I…
I surpriced myself with how easy it was to implement the PScript Interpreter and would like to share the basic technique that I am using. The language is still under development, but the idea is to have a minimalistic Interpreter that can be used embedded so I need a very small footprint on the core…
I draftet a specification for a PScript interpreter some time ago and have implemented a minimalistic version. Basically I am down on very small footprints using only 1020 bytes SRAM to execute a decent size script. I actually think I will try implementing this on an Arduino Uno just for fun, it is that small.…
This board can be purchased from Sparkfun for 215.- USD and is basically a breakout board for ZED-F9P from ublox. ZED-F9P can be purchased for 148.- USD in quantum of 10 units, but I only wanted two of these boards for now for my robot project. What is important with this is the 10mm precision…
I have written about this issue before, but ST never fail to suprice me on their SW quality – crap that don’t work: Bugs, bugs and bugs! I updated STM32CubeIDE to version 1.6.0 yesterday and discovered that the IDE fail to load the images – I had to default to STM32-Link Utility to be able…
Having worked with computers in 40+ years I must admit that I sometime dig into nostalgia and look at vintage computers before I recall how little you got done and how much time things took. The world has moved on – and thanks for that. RP2040 or Raspberry Pi Pico if you like is a…
This application is a replica of work I have done in Qt and C# before, but this time I use QML which is a very different technology. At first I must admit that it is overwealming and complex. One of the steepest learning curves I have experienced as it involves C++, Qt, QML, JavaScripts and…
One of the key features on the boards are that they assemble to a larger control system by just clicking them together. I have around 12 different boards by now and will start adding new boards and variants as I convert all my electronics from Target 3001 to KiCAD. These two board have 5V, Device…
Running a BLDC (3-phase motor) you need to insert and tune some parameters with regards to size of motor, number of winding, how much current do you output etc. But, more important is the algorithm and technique you chose matching the job at hand. You have three different algorithms (FOC, Sinusoidal, Trapezoidal) and a variety…
