关于单片机（51系列）通过GPRS模块和上位机进行通信-on SCM (51) GPRS modules and PC communication

本系统参照片上系统的设计架构、采用FPGA与SPCE061A相结合的方法，以SPCE061A单片机为进程控制和任务调度核心；FPGA做为外围扩展，内部自建系统总线，地址译码采用全译码方式。FPGA内部建有DDS控制器，单片机通过系统总线向规定的存储单元中送入正弦表；然后DDS控制器以设定的频率，自动循环扫描，生成高精度，高稳定的5Hz基准测量信号。-The system with reference to the design of system-on-chip architecture, used a combination of FPGA and SPCE061A approach to SPCE061A Singlechip for process control and scheduling core mission FPGA for external expansion, internal self-system bus, address decoding using the entire translated code approach. DDS has built internal FPGA controller, microcontroller through the system bus to the provisions of the storage unit into the sine table DDS controller and then to set the frequency, automatic cycle of scanning, to generate high precision and high stability of the baseline measurement 5Hz signal.

1.电子琴功能 用实验板上K1~K7作为电子琴的7个按键，每个按键对应一个音符要求当按下其中一个按键，就通过P2.5口输出对应频率信号使蜂鸣器发出特定音符声音。 2.乐曲演奏 若按下K8键，完成自动弹奏“送别”歌曲。 -1. Organ function of the experimental board K1 ~ K7 as the organ of the seven buttons, each button corresponds to a note of which require that when the press of a button, on the adoption of P2.5 port output frequency signal corresponding to a specific note to the buzzer sounds . 2. Music playing, if pressed K8 button to complete the auto-play " Farewell" songs.
