Comparing raw pin toggling speed between Arduino platforms.

Comparing raw pin toggling speed between Arduino platforms.

When comparing CPU's and architectures it is also a good idea to compare the frameworks and learn how the framework will affect your system.  In this article I will be comparing a number of popular Arduino compatible systems to see how different "flavors" of Arduino stack up in the pin toggling test.  When I started this effort, I thought it would be a straight forward demonstration of CPU efficiency, clock speed and compiler performance on the one side against the Arduino framework implementati

Comparing raw pin toggling speed AVR ATmega4808 vs PIC 16F15376

Comparing raw pin toggling speed AVR ATmega4808 vs PIC 16F15376 Toggling a pin is such a basic thing. After all, we all start with that Blinky program when we bring up a new board. It is actually a pretty effective way to compare raw processing speed between any two microcontrollers. In this, our first Toe-to-toe showdown, we will be comparing how fast these cores can toggle a pin using just a while loop and a classic XOR toggle. First, let's take a look at the 2 boards we used to c
