Title DESIGN OF DIGITAL STORAGE SYSTEM BASED ON AT24C1024EEPROM
Abstract Digital storage system can complete the data collection, data storage and other functions.It has a wide application prospect,in various industries will occupy an important position, more and more fields to a monolithic integrated circuits to control the use led as a display terminal equipment by some monolithic integrated circuits to control the object is intelligent control.
The design is to reduce costs, expand the development of the scope and the system running stability, reliability, designed by MSP430F149 and based on AT24C1024EEPROM,using analog digital circuit, microcontroller and integrated knowledge of measurement to complete the system design,I2C device in bytes, strings and pages according to the design requirements. while the design of the relevant multi-channel serial communication systems RS485/RS232 circuit and complete remote control of the data.
MSP430F149 is a 16-bit flash chips including the type of operation of a monolithic integrated circuits, the development of device easy, but the characteristics and programming for the control system design a great convenience., all modules of a schematic diagram of a circuit are protel 99SE to complete.
