V/F变换器作低成本A/D转换的方法与途径

A Interface between V/F Convertor and SCM as Low Cost A/D Conversion

提出了V F变换器通过与AT89C5 2单片机的接口来实现低成本A D转换的方法。由于利用了单片机的资源 ,故使得实现电路比较简单 ,可靠性好 ,且提高了转换精度。

In the paper a method is advanced that using V/F convertor with AT89C52 SCMInterface realizes low cost A/D Conversion .Because of using SCM resource ,circuit is simpler ,reliability is higher and precision of conversion is improved .Mutuai parametersare calculated ,flow charts and assemblers are given.
