【摘要】 根据高速定点DSP芯片TMS320F206的特点,提出了使用串行A/D转换器TLC2558作为DSP系统的模拟量输入部分,解决了以往基于并行数据传输的A/D转换器不能与高速DSP进行很好配合的问题。在此基础上设计了DSP与串行A/D转换器连接的硬件电路,并就A/D转换的软件设计时应注意的问题进行了探讨。更多还原

【Abstract】 This paper put forward a method that use serial A/D converter TLC2558as analog signals input of DSP system considering the characteristic of high speed fix-point Digital Signal Processor TMS320F206.It solves the problem that parallel-based da-ta transmission can not cooperate with DSP systems.On this basis,a hardware circuit is designed.At the same time,some problems in A/D conversion program design are discussed.更多还原
