I’ve made a build tool to replace make. It’s intended to be very similar to make, but with modern features that make lacks. Check it out on crates.io! Basic usage Make a file called tasks.su. Write the following in your taskfile. a.out: main.o % < *.o g++ $^ -o $@ Make sure the indentation is made with a hard tab. The syntax is very similar to Make, but unlike Make, pattern rules are separated from normal build rules....
I got very bored and decided to create a brushless DC motor driver pcb. It was pretty fun going through all of the design considerations, so here we go. Architecture The BLDC driver is intended to be run by a MicroMod controller. This is mostly because the club I’m at uses MicroMods extensively, and I wanted to put this in that same ecosystem. Despite what the schematic implies, power does actually come from the power section, it’s just that power symbols in KiCad are global and don’t show up on hierarchal schematics....
For the past couple months, I’ve been trying to get exceptions to work on AVR as a hobby project. After several months of work, I’ve done it. Exceptions work, you can just include <vector> and it just works. How to use it Currently I put prebuilt toolchains on github. My changes are currently a bunch of patches to gcc 13.2.0, binutils, and a few others. What I actually did I’ve reimplemented libunwind, the personality function, and also cfi macros by replacing them with my own stuff....
I was looking at I2C code, and noted that there was an awful lot of manual bit manipulation. Unfortunately the native solution in c++, bitfields, are non-portable and for that reason is discouraged in code bases. For that reason, I have written a library called bitstructs, which aims to do what bitfields do but portably. What are bitfields Bitfields are a bit of an obscure feature in C++, aimed at embedded developers....
