一个利用中断修改后进行的A/D采集功能的使用软件.-An interruption of the revised use of the A/D collection features the use of software.

linux 串口通信驱动源码,该代码能够接PC机键盘-linux-source-driven serial communication, the code can access PC keyboard

1) Project Description: this is a very simple frame sending test program. it will periodically sending frames.mainly used for demonstration and testing.2) Experiments and Notice 实验步骤和实验中的注意事项-- 发送模式有两种，无ACK发送，有ACK发送。-- 无ACK发送与sniffer配合测试，发送时红灯闪烁，sniffer通过串口显示cc2520 发送数据。-- 有ACK发送与cc2520rx配合测试，发送后，如收到cc2520返回的ACK则红灯闪烁表明发送成功，cc2520rx通过串口显示cc2520 发送数据。
