SEMAINE 1

Week 1 delves into the physical principles of diode junctions, transistors, C-Arduino programming, fixed-pattern signs, and an introduction to VHDL. Participants engage in remote experiences, including the creation of a chaser light.

SEMAINE 2

During Week 2, participants explore sequential logic circuits, input/output, pulse-width modulation (PWM), time-division multiplexing, and 7-segment 4-digit displays. The remote experience involves creating a 7-segment 4-digit display.

LA SEMAINE 3

Week 3 focuses on matrix displays, binary-coded modulation, permanent memories, counter sequencers, sequential circuits in VHDL, and LED properties. Participants get hands-on experience with an 8x16 matrix display.

SEMAINE 4

Week 4 delves into topics such as interruptions, timers, addressable LED ribbons, multiplexed matrix displays, programmable logic circuits (FPGA), and gamma correction. Remote experiences include creating a 16x16 matrix display and using LED ribbons on STM32.

SEMAINE 5

During Week 5, participants explore direct memory access, real-time clocks, remote control, specialized interpreted languages, controlling displays with an FPGA, and video and LED walls. Remote experiences include working with Nucleo STM32 and creating a 32x32 display on STM32.

SEMAINE 6

Week 6 covers advanced topics such as direct memory access, real-time clocks, remote control, specialized interpreted languages, controlling displays with an FPGA, and video and LED walls. Participants engage in remote experiences, including working with Nucleo STM32 and creating a 32x32 display on STM32.
