DCA1000EVM: 使用DCA CLI采集数据时遇到问题

Chenming He
Prodigy 150 points
Part Number: DCA1000EVM
Other Parts Discussed in Thread: AWR1642,

你好，我正在使用AWR1642+DCA1000在Ubuntu系统上采集数据

根据sdk_user_guide文档，我在启动AWR1642之后，依次利用DCA1000EVM_CLI_Control发送配置并进行数据采集

其中使用的json文件内容如下：

{
	"DCA1000Config": {
	"dataLoggingMode": "raw",
	"dataTransferMode": "LVDSCapture",
	"dataCaptureMode": "ethernetStream",
	"lvdsMode": 2,
	"dataFormatMode": 3,
	"packetDelay_us": 25,
	"ethernetConfig": {
		"DCA1000IPAddress": "192.168.33.180",
		"DCA1000ConfigPort": 4096,
		"DCA1000DataPort": 4098
	},
	"ethernetConfigUpdate": {
	"systemIPAddress": "192.168.33.30",
	"DCA1000IPAddress": "192.168.33.180",
	"DCA1000MACAddress": "12.34.56.78.90.12",
	"DCA1000ConfigPort": 4096,
	"DCA1000DataPort": 4098
	},
	"captureConfig": {
	"fileBasePath": "/home/hcm/Desktop",
	"filePrefix": "outdoor_capture",
	"maxRecFileSize_MB": 1,
	"sequenceNumberEnable": 1,
	"captureStopMode": "infinite",
	"bytesToCapture": 50000,
	"durationToCapture_ms": 5000,
	"framesToCapture":10
	},
	"dataFormatConfig": {
		"MSBToggle": 0,
		"reorderEnable": 1,
		"laneFmtMap": 0,
		"dataPortConfig": [
		{
			"portIdx": 0,
			"dataType": "real"
		},
		{
			"portIdx": 1,
			"dataType": "complex"
		},
		{
			"portIdx": 2,
			"dataType": "real"
		},
		{
			"portIdx": 3,
			"dataType": "real"
		},
		{
			"portIdx": 4,
			"dataType": "complex"
		}
		]
	}
	}
}

采集过程如下：

1、这里遇到了第一个问题，start_record成功，出现了outdoor_capture_Raw_0.bin文件，而stop_record时发生了报错，但同时一下子出现了outdoor_capture_Raw_1.bin~outdoor_capture_Raw_40.bin（因为我把maxRecFileSize_MB设置为1，每个.bin文件都很小）

看起来终止命令没有成功，但是数据依然保存了下来。我个人怀疑是json文件内参数的问题，但是没有在这个文档里找到各个参数的详细解析，请问在哪里有呢？比如captureStopMode这一项，显然有多个参数可选

2、现在我暂且认为采集的数据是正确的，我试着用它生成range-doppler、range-azimuth热图

此前，我已经成功解析了使用mmwave studio录制的数据，生成了正确的热图，但解析现在采集的数据时发生了错误。在我的理解中，每一帧数据有numTxAntennas * numRxAntennas * numLoopsPerFrame * numADCSamples个采样，每个采样是一个实部+一个虚部。但这和json里却有这样的配置：

"dataPortConfig": [
		{
			"portIdx": 0,
			"dataType": "real"
		},
		{
			"portIdx": 1,
			"dataType": "complex"
		},
		{
			"portIdx": 2,
			"dataType": "real"
		},
		{
			"portIdx": 3,
			"dataType": "real"
		},
		{
			"portIdx": 4,
			"dataType": "complex"
		}
		]

这似乎无法对应上，不知道是不是它导致的错误

希望您能解答我的两个问题，谢谢！

    你好，

    请问Linux下的CLI工具是你自己编译的么？能否在window下使用默认的工具测试一下，看是否有同样无法stop的问题?

    关于Json文件，请参考下面的论坛讨论：

    (+) IWR6843 and DCA1000EVM: I capture ADC Data on same scene with different method(mmWave Studio 2.1.1.0/ and mmw demo), the result on 1DFFT is different obvious - Sensors forum - Sensors - TI E2E support forums

    你好，请问Windows下的“默认工具”是指什么？

    win系统的CLI程序也需要自行编译生成，我尝试了一下，还出现了错误。。。

    我安装了mingw的make和g++，发生了这样的报错

D:\mingw\bin\make.exe: *** [Release\RF_API.dll] Error 1

    Ubuntu系统可以正确编译，但是stop_record仍会报错

    另外，您提到的论坛讨论涉及了数据的发布格式，这的确可能是我第二个问题的原因，我后续会确认一下。但这应该不影响数据录制，报错问题依然没有解决

    在C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\PostProc目录下有预先编译好的DCA1000EVM_CLI_Control.exe，请尝试使用，看是否报错。

    你好，

    请问你编译前是否有make clean？

    我这里没有编译环境，没有尝试过在windows或者Linux编译这个工具。

    你好，

    我是在新建的文件夹里编译的，一直有报错。目前怀疑是系统版本的原因，之后我会尝试用别的电脑重新编译。

    但是目前在Windows系统下采集的数据依然有问题：

    我注意到，您之前发的帖子里，发帖人有这样一段总结：

    1.1 The IQ swap set is different
    TestCase004 -- mmWave Studio Case

    ar1.ChanNAdcConfig(1, 1, 0, 1, 1, 1, 1, 2, 1, 0)
    the last param is IQSwap, which is 0

    TestCase006 -- mmw-LVDS case
    adcbufCfg -1 0 1 1 1

    <SampleSwap>
    ADCBUF IQ swap selection:
    0-I in LSB, Q in MSB,
    1-Q in LSB, I in MSB
    only option 1 is supp

    这指的应该是sample的实部、虚部顺序问题吧？我的理解是，DCA以2 lane传输，数据的格式应当以 real, real, imag, imag 排布，但是做FFT生成热图后依然是明显错误的。我尝试以 imag, imag, real, real 的格式解析，同样不对。

    请问这可能是什么原因呢？

    数据格式的错误原因找到了：

    lvdsStreamCfg -1 0 1 0

    awr的配置文件里应该这样设置，我之前按照sdk文档第13页的说明，设置了-1 1 1 1，这是不对的。。。
