Embedded Devices? What the Frack is that?

Yello!! This article is for both the newbies, who are looking for a quick introduction to embedded devices; or the pro who just wants to have a quick rewind of the key concepts of embedded devices.

If embedded devices are something you have not heard of I am sure you might have at least heard about Raspberry PIs.

What is Raspberry Pi?

Both ! But this article, we will discuss the one on the right.☝️

• Recently there has been a big shift in the kind of computing devices we find.
• No longer are computers always desktop or larger machines.
• We are finding smaller, cheaper, and lower power devices everywhere.
• This really started with mobile phone technology.

But recently devices like Arduinos and Raspberry Pis have gained a lot of attention.

• As developers, these devices provide us with great opportunities.

But we need to make sure that the code we develop is fast enough to work within the more demanding constraints of an embedded system.

The Arduino Project

Arduino Boards

Arduino Uno

• The most popular Arduino board is the Uno.
• It is a simple dev board with the following pin out:

6 analog input pins.

13 digital pins.

• Due to its popularity, a lot of boards use the same pin layout as the Uno.
• This makes it easier to support devices that were designed with the Uno in mind.

The Raspberry Pi

• The Raspberry Pi was created in 2012 by the Raspberry Pi Foundation.
• The original purpose was to teach Computer Science in developing countries.
• Designed to be a cost-effective complete SoC (System on Chip) capable of running a full Linux Operating System.
• Sold enormously well and used outside the realm of Computer Science. like,

IoT Development.

Robotics.

Hobbyists.

Secondary school teaching.

And so much more.
