Course M309 - Advanced C Programming of Microchip 32 bit Microcontrollers using MPLABX and the XC32 C Compiler

Duration: 5 Days

Intended Audience

Attendees should have some experience of embedded systems programming and a good basic knowledge of the C language, and have a keen interest in mastering more advanced algorithms and data structures of use in embedded systems application development.


The course emphasises the implementation of disciplined and well structured code and the design of modules with clean interfaces. Topics covered include:

  • Advanced use of dynamic data structures and algorithms for manipulating them.
  • Structured interrupt handling
  • Strategies and patterns for the implementation of basic multi-tasking applications
  • Basic and Extended finite state machines and their uses
  • More advanced data structures and algorithms - binary trees, heaps, hash tables, CRC checksums
