摘　　要：提出一种基于STM32F103单片机的用于电动车电池能量管理系统(EMS)的液晶显示触摸屏的设计方案,该方案以STM32F103作为核心控制器。STM32F103通过I/O口与四线电阻触摸屏相连,利用自带的A/D转换功能检测触摸并计算触点坐标实现触摸功能,并通过自身的I/O接口与TFT液晶屏模块实现通信,控制实现显示的功能。A LCD touch panel based on STM32F103 MCU design program which is used in EMS system is introduced in this paper,with STM32F103 as the core controller.STM32F103 is connected to four line resistance touch panel through I/O interfaces to monitoring touch and calculate the coordinates of contact by its own A/D conversion function to realize touch performance,and communicates with TFT LCD module through its own I/O interfaces to realize display performance.
