说明：  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
(Based on LPC1759 using the state machine to do CDMA module AnyDATA DTL518 code via DMA communication with UART1, do not take up CPU. Including the power-up sequence is initialized, dial-up connections, receive and process messages. Which use some library functions cortex-m3, online good looking)
