USB car simulation driving system

This solution simulates the design of a real car, using a microcontroller to connect to the steering wheel, clutch, brake and accelerator to capture operation feedback. The USB2.0 endpoint of the microcontroller is used to implement a USB composite device, which is suitable for simulated driving systems and game controllers.

The advantage of using NUC123 is the built-in 1T multiplier, which has powerful computing power and fast instruction processing speed, and the operating speed can reach up to 72MHz. And USB can support 8 endpoints to realize multiple applications of USB composite devices, and has passed USB professional certification.

This USB car simulation driving system includes a steering wheel, accelerator, brake, clutch pedal and gear lever. The USB is connected to the computer host; PWM capture captures the pulse wave of the steering wheel and controls the steering wheel motor to perform forced feedback of forward or reverse rotation. Through the software Controls the output and display of results on the screen. GPIO is used to control the car lights and read the gear position, and the 10-bit ADC is used to read the pedal simulation signal.

The advantage of NUC123 is that it has built-in UCID company code and UID chip unique code, which can effectively protect the system design from being stolen and cracked.

This solution has successful experience in mass production by customers, and solutions or reference designs are available for selection.
