基于KEIL C的RTXTiny操作系统的电话振铃检测程序。单片机为LPC900系列。 本程序并不能直接使用，但足以说明问题。如果您要使用您还需要定义相关变量等内容。 同时您还需要了解KEIL C的RTXTiny操作系统的使用。 有问题请MAIL ：xy-mcu@163.com-on KEIL C RTXTiny OS phone ringing detection procedures. MCU for LPC900 family. This procedure is not used directly, but suffice it to say. If you need to use your definition of relevant variables such content. While you also need to understand KEIL C RTXTiny operating system use. A question, please MAIL : xy-mcu@163.com
