摘　　要：在综合采集系统中,很多外接传感器都是串口通信。为了解决STM32采集系统中串口数量不足的问题,采用WK2168进行串口扩展。WK2168支持UART/SPI/IIC/8位并行总线接口并具有256级FIFO的低功耗4通道UART扩展芯片。该方案选择一路串口,扩展为4路UART,满足项目整体需求。Power standby mode in the integrated acquisition system, many external sensors are serial communication. In order tosolve the problem of insufficient serial port in the STM32 acquisition system, WK2168 is used to expand the serial port. WK2168 supports UART/SPI/IIC/8 bit parallel bus interface and has 256 level FIFO low power 4 channel UART expansion chip. Thisscheme selects one serial port to expand to 4 UART, to meet the overall needs of the project.
