Design of Multi-functional Steering Wheel Button Detection System for Automobile Based on STM32
Currently,the application of multifunctional steering wheels is becoming increasingly com-mon.To ensure the normal use of the multifunctional steering wheel buttons,it is necessary to conduct testing before leaving the factory.Therefore,it is necessary to design and manufacture a testing system that meets the requirements.This article innovatively proposes a hardware and software design scheme for detecting the resistance signal button and LIN signal button of a multifunctional steering wheel.A physical detection system is made to detect the resistance signal button and LIN signal button,and support multiple types of steering wheel detection.The experiment verifies that this scheme has strong practical value.
