An old joke in hardware engineering circles says, contrary to popular belief, electronic gizmos don’t run on electricity. They run on smoke. When something goes wrong, the smoke (sometimes accompanied by flames) escapes, and the device stops working.
We’ve discussed recently the importance of firmware engineering, especially in light of the coming deluge of Internet of Things (IoT) devices.
Today we go into a bit more detail about firmware development: How we got where we are in the evolution of firmware development, some of the main differences between firmware development and PC or mobile software development, and how those differences drive the execution of a firmware project.
