C standard libraries on bare metal

I am mostly doing development on devices that have ported Linux so the standard C library provides lots of it's functionality through implementing system calls which have a standardised behaviour. However for bare metal, there is no underlying OS.…

Do open source libraries exist for VHDL the way they do for C++ or python?

When I'm approaching a problem in C++ or python, there are many libraries that exist which do the heavy lifting of my code. I'm thinking about GNU GSL, BOOST, or FFTW for C++, and NumPy or SciPy for python. In many ways, the fact that these…

Altium Default Font

I want to change all default fonts of Altium to Arial, specifically in the Schematic. Right now they are Times New Roman. I changed my system font in my template but that doesn't seem to effect the components used in the schematics which make up 99%…

Conventional way to manage and use the libraries in Altium

I guess I have been always doing it wrong way because I don't have to use Altium so often. Whenever I start a project I create a schematic library (*.schlib) and a PCB library (*pcblib). And then I copy the symbols and footprints from other projects…

How to make an Arduino play a sound

What is the best way to make an Arduino play a sound file? Is there a code library or shield I would need? How would I store this sound file on the Arduino's chip? Is isn't very big, so I would be concerned doing this.

Creating a component library which includes distinct elements

I'm learning custom library design in Altium Designer. I designed several libraries so far (BJTs, resistors, capacitors, etc), all worked without any problem. This time I tried to design an IC package (TL082 Opamp) which contains two distinct…
