问题:

当我指定一个奇数位的采样点去进行采集或者生产的时候，我的数据采集设备（DAQ）会出现错误-10010。为什么？

解答:

一些DAQ设备采用的FIFOs要求数据是以32位增长的。一个单精度的16位采样点无法传进或者传出FIFO。基于这个原因，采集的采样点或者更新的用来生成的采样点的个数都必须是2的倍数，传统的DAQ驱动会返回错误-10010。这个要求影响下列设备：

• NI 6120 Simultaneous-Sampling Multifunction DAQ
• NI 611x Simultaneous-Sampling Multifunction DAQ
• NI 6711/13/15 Analog Output
• NI 6731/33 Analog Output

注意：使用DAQmx来代替Traditional DAQ，这个错误可以避免。见下面的KnowledgeBase 3NRBDARM链接。
