STM32主时钟输出的双机系统应用

摘要

介绍了STM32单片机主时钟输出功能,通过硬件设计和软件设计实现了主时钟输出功能、STM32单片机主时钟输出的波形展示,以及在空调控制系统中的应用.STM32 F030使用STM32 F205输出的时钟,可以正常稳定的工作,经过多台实际机组的长期运行测试,两个单片机工作都非常稳定.%In the paper,the main clock output function of STM32 is introduced.The functions of main clock output and the display of out-put are achieved through the hardware and software design,which has been used in the air conditioning control system.The STM32F030 uses the output clock of STM32F205,it can work normally.After a number of units in the long-term operation of the test,the two micro-controllers work stably.
