| 摘 要： | 在设计一个产品时,通常要用到串口通讯,而且往往需要多个串口来协调系统内分部件的工作.要在一个系统中实现多串口通讯有很多种方法,一般会选择一个单片机加外围串口扩展芯片的方案来实现.现讨论使用最少的资源(仅一个单片机)实现了3个以上串口通讯的解决方案.

| Abstract: | In designing a product,the UART communication technology is often used,or exactly speaking,Multi-UART is also required to coordinate the work of other sub-components in a system.In view of this point,or in order to realize this Multi-UART communication technology,there are a lot of methods,but at most time,a common method that a microchip in combination with peripheral circuit is applied.Therefore,the least resources(only one Microchip)is used to achieve more than three serial communications technology. |
