Arduino Sketch compilation, cost of virtual tables, Wire memory use - part 2
In part 2 of this series we discuss how sketches compile on Arduino, along with the cost of using the virtual keyword to create virtual classes. Some things are not quite as clear cut as may be initially thought, especially in the very low memory environment of the ATMega328 (Arduino Uno). Lastly we discuss the memory usage of Wire and how...
Evaluating static memory (SRAM) usage in an Arduino Sketch - Part 1
While writing IoAbstraction and TcMenu, I noticed that SRAM memory usage seemed to increase at a rate greater than what seemed right by static evaluation of all the objects I had created. This will become a series of articles on the subject of efficiency in microcontroller environments. In this part, we'll look at how to evaluate memory on your device, and...
How the Arduino memory model works - for AVR
An overview of memory organisation All general purpose processors, be it Intel, ARM or AVR devices work by reading instructions from memory and executing them. They are generally based on one of two Architectures: Von-Neumann or Harvard. The vast majority of larger systems such as PC's and mobile devices use Von-Neumann, but AVR processors in Arduino boards such as Uno and...
