stm32f4发现rc522 pre源

通过W5200芯片连接网络，实现DHCP，DNS，UDP，TCP通讯，W5200内部自带TCP协议栈，通过SPI接口连接单片机，此代码单片机为STM32F103 VBT6，可同时实现8个SOCKET

基于LPC1759用状态机做的CDMA模块AnyDATA DTL518的代码，通过DMA与UART1通信，不占用CPU。主要包括上电时序初始化，拨号连接，短信接收和处理。其中用到cortex-m3的一些库函数，网上很好找

我一直在用的I2C总线函数库,内容不多,但很实用.--在网上见的资源挺多,但很多时候是没有测试过的,下了一大堆,搞得眼花燎乱.这个是我在某人主页上找到的,经修改调试后,一直在用着的,绝对好用.-I have been using the I2C bus in the library, which is not big, but very useful .-- online resources挺多see, but often is not tested, and under a lot of, in a confused chaos burn. This is my home page to find a person, and debugging, as amended, has been with the absolute ease of use.
