Verilog_Louis/Semaine_3/Capteur_recule_bidirectionel_V2/Ultrasonic/sim.out
Gamenight77 1811301ef2 Refactor ultrasonic_fpga and ultrasonic_sensor modules for improved functionality 
- Initialized registers in ultrasonic_fpga to avoid undefined behavior.
- Modified state machine in ultrasonic_fpga to include a COMPUTE state for better echo measurement handling.
- Adjusted echo counting logic to ensure accurate distance calculation.
- Updated ultrasonic_sensor to allow for a more flexible trigger pulse timing by reducing the threshold for valid triggers.
