Programming PIC Microcontrollers with XC8 (eBook)

Armstrong Subero has been tinkering with electronics for as long as he can remember. The thrill of creating something from the ground up and watching it work is something that one never shakes. His entire life changed when he discovered microcontrollers. They were so powerful and simple and complex, all at the same time. After finishing school, Armstrong taught himself programming. Armstrong landed his first job as a Systems Technologist completely self taught and a lot of it was due to his in depth knowledge and passion for microcontroller technology. He has used many microcontroller families during the course of his work, however he has an affinity for PIC microcontrollers. Armstrong currently works for the Ministry of National Security in his country and designs robots as well as write books, blogs and software on trinirobotics.com and angelstemlabs.org in his free time.
