Library
I enjoyed the ready-to-use library that was provided with the Keil environment by Luminary Micro. Microcontroller manufacturers usually want to sell the idea of compatibility between their microcontrollers, but you usually have to work and look through their datasheets to really move from one microcontroller to another. That’s what Luminary Micro does for you; it maintains a set of functions that works for their entire family of microcontrollers. You don’t have to care about how a particular function in the microcontroller works; you just have to read the library manual. The advantage of that philosophy is that you can quickly write readable working code. The drawback is that you don’t have to read the datasheets and you’re moving away from the hardware. Another drawback (when size matters) is that the use of the library produces bigger code. Nevertheless, this is not an issue because the source code from the library is provided so you can still extract the only functions you need to fit into your projects.
