Life As an Embedded Software Developer
Let’s now take a brief look at some of the qualities of embedded software that set embedded developers apart from other types of software developers. An embedded software developer is the one who gets her hands dirty by getting down close to the hardware.
Embedded software development, in most cases, requires close interaction with the physical world—the hardware platform. We say “in most cases” because there are very large embedded systems that require individuals to work solely on the application-layer software for the system. These application developers typically do not have any interaction with the hardware. When designed properly, the hardware device drivers are abstracted away from the actual hardware so that a developer writing software at the application level doesn’t know how a string gets output to the display, just that it happens when a particular routine is called with the proper parameters.
- Hardware knowledge
The embedded software developer must become intimately familiar with the integrated circuits, the boards and buses, and the attached devices used in order to write solid embedded software (also called firmware). Embedded developers shouldn’t be afraid to dive into the schematics, grab an oscilloscope probe, and start poking around the circuit to find out what is going on.
- Efficient code
Because embedded systems are typically designed with the least powerful and most cost-effective processor that meets the performance requirements ...
