设计资料
Because this design uses multiple serial ports,比如使用了GSM通信,Fingerprint communication,Voice broadcast communication,The communication methods used by these three modules and the microcontroller are serial communication,Set the matching baud rate.The system uses a variety of modes of input,矩阵键盘,红外遥控,ICCard input, etc,Therefore, the difficulty of design lies in the integration of multiple modules,The workload of the system is relatively large.The information that explains the testing process is relatively complete.
