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。
According to the characteristics of high-speed fixed-point DSP chip TMS320F206, it is proposed to use the serial A / D converter TLC2558 as the analog input part of the DSP system to solve the problem that the A / D converter based on parallel data transmission can not well cooperate with high speed DSP The problem. Based on this, the hardware circuit of DSP and serial A / D converter is designed and the problems that should be paid attention to when designing A / D converter software are discussed.
