Introduction This post begins a series of investigation and examples for the STM32 processors. Specifically I will be looking at STM32F405RGT6 which is the processor used on the VESC (by Benjamin Vedder) which I have bought one copy of from ebay. Thus the long goal will be to replace the software on the board byContinue reading “STM32 Getting started”

Suppose you have an ADC signal e.g 12-bit value that needs to be scaled. If your processor is for instance an 8-bit AVR and/or you have few cycles to waste on scaling you cannot afford using floating point arithmetic and not even division. Often the following scheme can be used with sufficient accuracy: Suppose itContinue reading “Trick for scaling in embedded processors”

As a follow up on my last post – I created a Github repository for code that can be used to visualise cellular automata in Factor (using OpenGl). https://github.com/lonelab/cellularautomata Just copy the contents into the factor source tree under work/cellular and you should be able to run it the usual way… (see http://www.factorcode.org) Then picturesContinue reading “Fun with Factor and cellular automata”
