Embedded interface of automobile switch detection control system

An embedded interface of an automobile switch detection control system is composed of an ARM processor, a driving circuit, a servo and stepping motor set, a field sensor and an A/D conversion device,and the structure of the embedded interface is shown in the figure 1. A general purpose input/output port GPIO of the ARM processor is respectively connected with the driving circuit and the A/D conversion device; three groups of output signals of GPIO (General Purpose Input/Output) control a servo motor and a stepping motor through a driving circuit to generate control on three actions of pressing, screwing and shifting of an automobile switch; and three groups of input signals of GPIO are used for receiving the automobile switch closing state acquired by the A/D conversion device and detected by the field sensor, so that the parallel detection process of the automobile switches with three different actions is completed, and the universality and the detection efficiency of the system areimproved. 一种嵌入式汽车开关检测控制系统的
