Design of Wireless Sensor Networks Node applied to ADXL345

摘要

The integrated and structured design of Wireless Sensor Networks node applied in acquisition and transmission of vibration signals were introduced. Then the interface of each module is analyzed and the program is designed. The problem of sensor and microprocessor timing mismatch was solved by ADXL345. All functional registers and initialization of ADXL345 were proposcd,and the sensor's multi-valued literacy program were designed.
