Design of GPRS Based on MCU STC12C5A60S2
The MCU has the smaller volume, low cost, face control, antijamming ability strong and so on merits, GPRS is based on the GSM development foundation in data traffic. one kind of GPRS system Has been designed by using MCU STC12C5A60S2, it including correspondence transformation connection, SIM300 module, MCU, display circuit, keyboard electric circuit, RS232 exterior serial communication connection and so on. The related hardware welding on the PCB, the software programming after-burning writes in the MCU, inserts the liquid crystal display monitor and the SIM card, joins the receiver and the microphone, connects the good GPRS antenna. On the electricity, the establishment correspondence transformation connection, may realize the close-down, the dial and the answering telephone, transmits and receives the SMS, to receive and dispatch E-mail, carries on the Internet to glance over and so on, indicated that has achieved the design requirements.
