The volatile keyword
Although the C keyword volatile is very useful in embedded applications, care is needed to use it correctly and vigilance is required to ensure its correct implementation by compilers.
++i and i++ : what’s the difference?
Although the ++ and -- operators are well known, there are facets of their operation and implementation that are less familiar to many developers.
Remember Y2K?
There was fear that the turn of the century at the end of 1999 would cause problems with many embedded systems. There is evidence that the same issue may occur in 2038.
More than just a pretty face - a good UI is essential
A user interface can make or break a device - determining its success in the marketplace. With careful design, the UI can make the product compelling and result in a high level of satisfaction from new and experienced users.
Software is free and can right any wrong
Software changes are so much easier than hardware modifications, so the temptation is always to take this approach to fixing bugs. This may not always be a good idea.
There are 10 kinds of people in the world
It is useful, in embedded software, to be able to specify values in binary. The C language lacks this facility. In this blog we look at how to fix that.
Who needs source code?
Many developers feel that the supplying source code is essential for licensed software components. There are other perspectives, including the possibility of it being an actual disadvantage. Even the definition of source code has some vagueness.
Assembly language is best - except when it isn’t
A look at why writing in C often produces more efficient code than hand-written assembly language.
Stand-by or boot-up
Many factors affect the usability of devices - a key one is how long it takes to start up.
Graphical medicine
Although an appealing user interface is a good option for any device, in medical applications it can be a life saver.
A design non-methodology
Although writing an RTOS or kernel may be an interesting project, it is unlikely to be a wise course of action.
Core competencies
Creating software from scratch is attractive, as the developer has total control. However, this is rarely economic or even possible with complex systems and tight deadlines.

Small or fast?
Developers of software for desktop computers take code optimization for granted. Embedded developers typically need to pay much more attention to the details
Product quality: belief or proof?
Embedded software development is a challenging activity, so it is essential to have tools and IP that is of the best quality. However, assessing that quality can be, in itself, a challenge.

OS influence on power consumption
Power consumption of an embedded system may be influenced in software in general, but selection of an operating system can be key.
Static or static
The keyword static in C and C++ has multiple uses, which are not always well understood.
