如何在不适用dca1000收集板的情况下,使用iwr6843+MMWAVEICBOOST采集raw adc data?之前找到一个文档好像是官方的demo
Mmwave Radar Device ADC Raw Data Capture
To access ADC data from mmWave sensors, user need to program various basic components within the device in a given sequence. In order to help
user understand the programming model needed to configure the device and generate ADC data in device's L3 memory, an example usecase is
provided under mmwave_sdk_<ver>\packages\ti\drivers\test\mem_capture. Refer to the doxygen documentation located at mmwave_sdk_<ver>\pack
ages\ti\drivers\test\mem_capture\docs\doxygen\html\index.html for more details.
但是有点看不明白,谁可以解释一下 或者提供一下想法么
Shine:
这个文档里的mem_capture demo是老版本的SDK1.2之前的版本里的,现在的SDK里已经没有这个demo了。
目前都是通过DCA1000EVM采集数据的。如果不用DCA1000EVM的话,需要自己修改代码实现。请参考下面的帖子。https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/765864/mmwaveicboost-about-getting-adc-raw-data-with-mmwaveicboost-starter-kit

你好Shine
目前我想基于芯片开发做实时的IQ数据传输处理,所以需要舍弃掉dca1000开发板,请问有什么解决方案么?

Shine:
是要通过SPI口或者uart口来传输数据吗?SPI和uart的传输速度要比lvds口慢,不适合传输大量的数据。如果您一定要做的话,可以参考C:\ti\MMWAVE-SDK 03_05_00_04\mmwave_sdk_03_05_00_04\packages\ti\drivers\spi\test\xwr68xx里的例程。

对的 目前就是通过XDS110 USB与PC连接,想通过这个口来传输ADC数据 请问有合适的demo么?

Shine:
抱歉,没有demo。
