ZeroOverheadCPP

Exploring the concept of Zero Overhead C++ in Microcontrollers.

Setup

• cmake
• avr-gcc 10.1.0
• Arduino UNO

Folder Structure

• app: The program files implementing some kind of blink program
• bin: The resulting binary files. I only commit the .lss files, not the .elf nor the .hex nor the .map files.
• build: See Building
• lib: The zero overhead library

Basic Concept of ZOL

The basic concept is that the compiler produces the same Assembler Code for the C and the C++ program.

Building

Please execute the following commands:

mkdir build
cd build
cmake ..
cmake --build .

You'll find the compiled output files in the bin folder.

Goals

Provide similar functionality to the Arduino Libraries. Have a nice API. Be as fast as C.

ToDos:

Basically, the headings from the Arduino Reference.

• Digital I/O
• Analog I/O
• Time
• Math
• Trigonometry
• Random
• Communication
