I^2C总线技术在DSP系统中的实现

The Implementation of I^2C Bus Technology in DSP System

许多嵌入式系统处理器由于不带有I2C总线接口而限制了I2C总线接口器件在其上的应用。介绍了I2C总线的特点和时序,并以串行E2PROM为例,给出了在TMS320F240X DSP系统中模拟实现I2C总线的方法。实践证明,该方法简单、可靠,对于构建实际的DSP应用系统来说具有现实的参考价值。

Many embedded system processor can not use I^2C bus devices because of its lack of I^2C bus interface. This paper introduces the character and time sequence of I^2C bus and taking serial E2PROM as example and presents the simulating application method of I^2C bus in DSP system. The practice proves that this method is simple and reliable and gives practical reference value for actual construction of DSP application system.
