STM32 development board example: Timer. Development Environment: Keil For ARM

这是以太网芯片W5500的UDP最新例程代码，基于Keil4.72版本，主控芯片为STM32F103RCT6。用户下载并烧录入MCU中Reset后，在PC上用网络调试助手虚拟一个UDP Sever/Client，W5500可以作为UDP Client/Server同PC进行数据通信测试，需注意服务器和客户端的IP及端口设置。W5500是一款全硬件TCP/IP协议栈以太网芯片，代码简单，移植到其他单片机平台非常方便。

采集AIN0和AIN1的信号，通过可调电阻，使输入的模拟信号发生改变，来进行A/D转换。为保证数据的准确性，通常采集10次以上，在求平均值。A/D转换器采集AIN0和AIN1的信号,并显示出来。-AIN1 acquisition and AIN0 signal, through an adjustable resistor, so that the analog signal input to change, to carry out A/D conversion. In order to ensure the accuracy of the data is usually collected 10 times more than the average in the order. A/D converter and acquisition AIN0 signals AIN1 and displayed.
