Digital electronics

Digital electronics viewed from its two most common aspects:

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

 - Microcontroller programming. Implementation of standard features in C language (learned in the first semester): bus communication, sensor and actuator interfacing, and time-sharing management.

• Knowing standard combinatorial functions
• Understanding the difference between a combinatorial system and a sequential system
• Know the basics of sequential logic
• Know how to analyze and synthesize standard sequential functions
• Knowledge of the architecture and features offered by microcontrollers
• Implementation of these features
• Criteria for selecting a microcontroller for a given application.

• Combinatorial systems
• Simplification of logical functions
• General syntax of the C language (typically the first semester program)

Written exam: 70% of the final grade

Practical work: 30% of the final grade

Schedule: 9 a.m. lecture — 1:30 p.m. tutorial — 6 p.m. practical

Standard combinatorial functions

• information switching, comparator circuit, parity and oddity check
• multiplexers and demultiplexers
• encoders, decoders, and transcoders
• arithmetic circuits

Sequential systems:

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

Microcontrollers: 7:30 a.m. lecture — 3:00 p.m. lab

• Conventional processor vs. microcontroller. Libraries, presence or absence of an operating system.
• Architecture and Mapping: RAM, Eprom, computing power, registers associated with microcontroller functions.
• Analog and digital interfaces (GPIO, DAC, PWM). Port configuration and use.
• 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 interrupts. Case studies:
  - Polling vs interrupts (application to buses)
  - Management of "basic tasks" in time-sharing: cooperative vs preemptive multitasking
