采用T1公司CC2530芯片,设计了一种利用基于ZigBee的压力传感器实现对大气压力进行检测的系统。采取IO口模拟I2C时序来实现I2C的通信方式,规避了由于CC2530自带的I2C接口的不稳定所造成的数据结果不准确的后果。
Adopt T1 company CC2530 chip, designed a system that uses the ZigBee-based pressure sensor to detect atmospheric pressure. Take IO port to simulate I2C timing to realize I2C communication mode, and avoid the inaccurate result of data due to instability of CC2530’s own I2C interface.
