Basic knowledge

This section is a good starting point for those who aren’t familiar with embedded systems: it contains a series of articles not related to a specific topic. They should be read to build a background knowledge required to work with embedded systems.

C Library design for embedded applications: tips and hints

C Library design: tips and hints

Write reusable code is one of the most powerful and time-saving thing that an embedded programmer should learn. Compose well-arranged libraries makes things easiest, especially when we want to add old code in a new project. Citing one of the most talented programmers I have ever met, “Well done code should be like a LEGO: must fit perfectly and without any effort”. So a good library should be quite abstract, with a simple hierarchy and should provide some well documented APIs.

Even if this is a generic embedded article, we will provide some concrete example.

Registers and bit masks

Registers and bit masks

When I started with embedded my knowledge about programming was (and probably still is) very elementary. I often used logical operator like logical NOT (!), logical OR (| |) and logical AND (&&) but was almost ignoring the bitwise operators.SL Plugins

Handling registers is actually so simple that at first approach I wasted a couple of days and this was because bitwise operators are required to. Talking with friends of mine coming from Arduino, this problem seems to be much diffused. The trap seems to be a lack of basic knowledge of informatics and electronics. So in this continue reading...
