ModbusTCP监控程序
资源描述
这里先传个代码的文件先看看吧。TCP的协议样例如下:
请求和响应带有六个字节的前缀,如下:
byte 0: 事务处理标识符 –由服务器复制 –通常为 0
byte 1: 事务处理标识符 –由服务器复制 –通常为 0
byte 2: 协议标识符= 0
byte 3: 协议标识符= 0
byte 4: 长度字段 (上半部分字节) = 0 (所有的消息长度小于256)
byte 5: 长度字段
(下半部分字节) = 后面字节的数量
byte 6: 单元标识符 (原“从站地址”)
byte 7: MODBUS 功能代码
byte 8 on: 所需的数据
因而处理示例“以4的偏移从UI 9读1寄存器”返回5的值将是

This code will be useful to you if you have tried using ADOCE, but never got anything to work. It is not meant to be integrated into any application, but rather it should be used for demonstrative purposes. It clearly shows the basics of how to use the technology.

STM32F407 USB讀卡器
此源碼實現的功能:開機的時候先檢測SD卡和SPI FLASH是否存在,如果存在則獲取其容量,並顯示在LCD屏上面(如果不存在,則報錯)。之後開始USB配置,在配置成功之後就可以在電腦上發現兩個可移動磁盤。代碼用的是探索者STM32F407開發板實現,所用到的硬件資源如下: 1)指示燈 2)串口 3)TFTLCD模塊 4)SD卡 5)SPI FLASH 6)USB SLAVE接口
