Parts

This project is based on the STM32L476 Discovery Board. The primary peripherals, both external and on the board, are listed below:

• 2 external ultrasonic sensors (HC-SR04)

• 1 external speaker

• audio jack (on board)

• button (on board)

• LCD (on board)

This will involve the use of the following serial interface protocols:

• I²S

• I²C

It will also involve PWM to interface with the ultrasonic sensors.
