Hello people! I hope you are well!

In this article I would like to present you a simple C++ 3D vector library. This is just a prototype and I am sure you can find other better and more complete alternatives. So, we are just dealing here with a “Yet Another 3D Vector Library”.

I created this library because I wanted to reuse some 3D vector operations in various OpenGL computer graphics exercise programs (from my M.Sc. studies). Of course, I could use an already existing library. However, I wanted also to understand how some basic 3D vector operations work.

Generic C++ template functions for reading from / writing to the Arduino EEPROM memory.

Hello my Arduino fellows! How are you? The summer is hot! 🙂 In this post I would like to share with you two generic C++ template functions for reading from / writing to the Arduino EEPROM internal memory. I have used in the past these functions successfully in a project and I think that might be also useful to you.

It is a fact that just by looking the contents of a single byte in any memory we are not able to say what the data actually mean. The data or the bit pattern that appears has any meaning we want. It is always the context that gives meaning to data. It could be a memory address, an unsigned integer, a two’s complement signed integer, a machine opcode, an opcode operand, an IEEE-754 floating point number, an ASCII character, noise 🙂
