This book is unique in presenting the scope, the topic of integrated balance assembly language programming, microcontroller programming via the C language, and interface hardware. Programming topics are discussed using both assembly language and C, while hardware interfacing examples use C to keep code complexity low and improve clarity. The topics emphasize the linkage assembly language programming between the C language constructions and their assembly language equivalents, so students clearly understand the impact of C coding choices in terms of execution time and memory requirements. Hardware interface topics included in the book cover the fundamental (parallel, serial, interrupts, A / D, D / A) using a device that does not require extensive background circuit. Laboratory project provides experience of off-the shelf-wide laboratory (13 trials) for using the PIC18: one experiment in introductory computer architecture topics, four experiments on PIC18 assembly language, and eight hardware experiments.
