hi,
When I try to combine capture demo into MMW demo, which only set LVDS output while common chirp processing is enabled. (SDK1.1)
The main part of modification is adding CaptureDemo_configureStreaming function and other modification is as attachment:
The main problem is, when code ran into rlDeviceSetHsiClk function, and it will come out some error :
