DCA1000EVM: DCA1000EVM捕获数据问题

我使用的设备是IWR6843AOPEVM Rev G + DCA1000EVM 捕获原始的ADC数据

数据捕获过程中能够正常使用 但是少了一半的帧

正常捕获后的数据大小为 4 x 3 x 128 x 256 x Frames x 4bits

我捕获的ADC数据大小会小一半

调用rawDataReader.m 验证也是只有一半的帧（No of Freams 为25

每帧里面数据格式正常

附上xx.mmwave.json文件

捕获完数据后为提示一个这个信息：（我设置成4帧 也只是只有一半

Chris Meng：

你好，

使用mmwave studio自带的默认的DataCaptureDemo_xWR.lua能否复现你的问题？

你应该是修改了LUA。
