Digital electronics

Digital electronics seen under its two most common aspects:

  - Combinatorial logic and logic gates: Combinatorial and sequential aspects (flip-flops, counters, frequency dividers, registers).

 - Programming of microcontrollers. Implementation of the usual functionalities in C language (learned in the first semester): communication by bus, interfacing of sensors and actuators, and time sharing management

• Know the standard combinatorial functions
• Understand the difference between a combinatorial system and a sequential system
• Know the basic elements of sequential logic
• Know how to analyze and synthesize standard sequential functions
• Knowledge of the architecture and functionalities offered by microcontrollers
• Implementation of these features
• Criteria for choosing a microcontroller for a given application.

• Combinatorial systems
• Simplification of logic functions
• General Syntax of the C Language (typically the 1st semester program)

Written exam: 70% of the final grade

Practical work: 30% of the final grade

Logic : 9h CM - 13h30 TD - 6h TP

Standard combinatorial functions

• information routing, comparator circuit, parity and imparity check
• multiplexers and demultiplexers
• encoders, decoders and transcoders
• arithmetic circuits

Sequential systems:

• notion of state, synchronous and asynchronous systems
• flip-flops: elementary components of sequential logic RS, JK, T, D
• standard sequential functions (analysis and synthesis): counters/decounters/frequency dividers, registers

Microcontrollers : 7h30 CM - 15h TP

• Classic processor vs. microcontroller. Libraries, presence or absence of operating system.
• Architecture and Mapping: RAM, Eprom, computing power, registers associated with microcontroller functionalities.
• Analog and digital interfaces (GPIO, DAC, PWM). Configuration and use of ports.
• Communication via RS-232 bus (or RS-232 emulated on USB) : case of interaction with a computer (local data feedback).
• Industrial buses (I2C and SPI): basic operation
• Hardware and software interruptions. Case studies:
  - Polling vs. interrupts (application to buses)
  - Management of "basic tasks" in time-sharing: cooperative vs. preemptive multi-tasking
