Lessons : 16 h TD : 0 h TP : 34 h Project : 0 h Total : 50 h
Co-ordinator : Dimitri Boudier
Prerequisite
- Bases in C langage (procedural langage, etc)
- Bases in software development tools (IDE, UNIX shell, Makefile, etc)
- Bases in numerical systems (combinatorial et sequential analysis, boolean algebra, etc)
- Bases in analogical systems (active and passive components, electrical diagram reading, etc)
Course Objectives
- Understand the functionning and the architecture of a CPU (Central Processing Unit) base numerical processor, like MCU family (Micro Controller Unit).
- Develop a drivers library and an embedded application on MCU
- Create the documentation of the solution
Syllabus
During main Courses (with demonstrations) :
- Introduction of embedded domain
- Heterogeneity of processors architectures
- Introduction of MCU family
- PIC18 MCU architecture from Microchip
- PIC18 MCU assembler from Microchip
- Scheduling and development of an embedded baremetal (without Operating System) application
- Introduction of communication networks (wire and wireless)

During Practical Works (development of a firmware for a bluetooth speaker) :
- Development of a BSP (Board Support Package) from scratch at the register stage
- Development, test and validation of drivers functions (GPIO, Timer, UART, Bluetooth, etc)
- Development, test and validation of an embedded application with offline scheduler (bluetooth speaker)
- Documentation of solutions
Practical work (TD or TP)
