  • The Kannel Open Source WAP and SMS gateway works as both an SMS gateway, for implementing keyword b

    The Kannel Open Source WAP and SMS gateway works as both an SMS gateway, for implementing keyword based services via GSM text messages, and a WAP gateway, via UDP. The SMS part is fairly mature, the WAP part is early in its development. In this release, the GET request for WML pages and WMLScript files via HTTP works, including compilation for WML and WMLScript to binary forms. Only the data call bearer (UDP) is supported, not SMS.

  • TLV1544与TMS320VC5402通过串行口连接

    TLV1544与TMS320VC5402通过串行口连接,此时,A/D转换芯片作为从设备,DSP提供帧同步和输入/输出时钟信号。TLV1544与DSP之间数据交换的时序图如图3所示。 开始时, 为高电平(芯片处于非激活状态),DATA IN和I/OCLK无效,DATAOUT处于高阻状态。当串行接口使CS变低(激活),芯片开始工作,I/OCLK和DATAIN能使DATA OUT不再处于高阻状态。DSP通过I/OCLK引脚提供输入/输出时钟8序列,当由DSP提供的帧同步脉冲到来后,芯片从DATA IN接收4 b通道选择地址,同时从DATAOUT送出的前一次转换的结果,由DSP串行接收。I/OCLK接收DSP送出的输入序列长度为10~16个时钟周期。前4个有效时钟周期,将从DATAIN输入的4 b输入数据装载到输入数据寄存器,选择所需的模拟通道。接下来的6个时钟周期提供模拟输入采样的控制时间。模拟输入的采样在前10个I/O时钟序列后停止。第10个时钟沿(确切的I/O时钟边缘,即上升沿或下降沿,取决于操作的模式选择)将EOC变低,转换开始。
