摘　　要：以Nucleo 144 STM32F767板为硬件平台,基于Nuttx系统探究了USB CDC/ACM串行设备实现方式。该实现方式有别于传统桌面Linux操作系统和其他IoT操作系统,采用从应用层发送控制命令字到内核空间达成USB CDC/ACM串行设备实现策略,并使用Debian9.0系统和Nuttx系统的NSH shell环境验证了USB CDC/ACM串行设备的正常工作。The Nucleo-144 STM32F767 board is used as the hardware platform,and USB CDC/ACM serial device implementation method is explored based on the Nuttx system.This implementation is different from the traditional desktop Linux operating system and other IoT operating systems.The application layer sends the control command word to the kernel space to load the USB device driver,and the normal operation of the USB CDC/ACM serial device is verified by using the Debian 9.0 system and the NSH shell environment of the Nuttx system.
