[参考译文] DCA1000EVM：DCA1000EVM 实时数据记录

您好：

您是否配置了有限数量的帧？ 如果您正在配置无限数量的帧、那么您需要调用  AR1.StopFrame () API、否则它将继续无限期地成帧、并且您将溢出 DCA1000上的内存。

此外、DCA1000不支持"实时"数据采集。  DCA1000上的存储器已满后、捕获将失败。 您需要在存储器已满之前停止采集并将数据发送到 PC。  

此致、

Adrian

感谢您的答复！

是的、我使用  ar1.FrameConfig (0、1、1、10、2、 0、0、1)。  

我知道没有"实时"数据采集！ 我可能在错误的上下文中使用过。 我想尽快更新数据文件、以便处理后续数据。 是否有更好的替代方法可以这样做？

您好：

是否可以共享完整的 lua 文件？ 根据当前信息、我在您的程序中没有看到任何错误。

此致、

Adrian

您好：

如果延迟2秒、就不会有2秒的拍摄时间。  

捕获时间由 No. 样品和帧。 目前、无论捕获时间如何、代码都会等待2秒、因为之后没有其他命令。 如果有一个停止帧命令、则  

我建议计算捕获所需的确切时间、然后等待该时间。

您好、  

感谢您发送编修。 因此、我尝试记录8个 Rx 通道、用于10个线性调频脉冲和128个 ADC 样本。 是否有方法可以为 capture 命令指定此值、而无需使用 sleep？
