摘　　要：提出了一种基于Atmega8和Stm32F101双处理器的投影机升降控制设计方案,介绍了其电路组成、功能以及软件流程。其中Atmega8负责数据采集,Stm32F101实现对电机的控制,处理器间通过I2C总线进行通讯。系统采用了红外遥控或外部按键输入装置控制,也可以用PC机联机控制。试验验证设计方案正确、有效,定点精度符合实用要求。This paper presents a design of projector lift control based on dual processor aanega8 and stm32f101 and introduces its circuit composition, function and software processor. In the design, stm32f101 is responsible for motor control, and Atmega8 is responsible for data collection. The processors communicate through the I2C bus. The system uses an infrared remote control or external keystroke, or it can also use pc-on-line. The test verifies that the design is proper and effective and its fixed-point accuracy meets the practical requirement.
