| 中文摘要: |
| 在STM32处理器平台上使用USB HID接口协议设计了一种低成本的多功能控制器，控制器通过USB接口收到上位机指令后可进行变频、变占空比的PWM信号输出、GPIO读入和输出、模拟量AD采集等多种功能；上位机软件采用一组通用的HID接口的API函数实现对下位机硬件的读写控制，而且免驱安装，能显著降低开发成本。实验验证的结果表明，系统可以稳定运行。 |
| 英文摘要: |
| On the platform of STM32, a multi-purpose controller is designed with USB HID protocols, which can change the frequency, output the PWM with the changed duty ratio, read and output the GPIO, collect the analog quantity AD data and etc. after receiving the command from the master computer through the USB. The software of the master computer applies a group of API functions of the universal HID to control the reading and writing of the slave computer, which can significantly reduce the development cost with no driver needed. The experimental results show that the system can run stably. |
