Linux/IWR1443BOOST: The upper and lower limits of MMW_MAX_OBJ_OUT.(Displayable range value.)

Hello,

The lower limit for MMW_MAX_OBJ_OUT is 1, which may not be useful, while the upper limit depends on the available DATA_RAM memory. You can check the unused DATA_RAM memory as highlighted below in the map file to see how much memory you have left.

The total DATA_RAM needed for MMW_MAX_OBJ_OUT is given by MMW_MAX_OBJ_OUT*sizeof(MmwDemo_detectedObj). For instance, increasing the MMW_MAX_OBJ_OUT from 100 to 200 increases the used DATA_RAM in the map file by 100*sizeof(MmwDemo_detectedObj) or 1200 bytes.

However, please note that we have not tested increasing MMW_MAX_OBJ_OUT beyond the value defined in the SDK demo and in addition to memory allocation, the maximum no. of detected points sent out may be limited by the UART data rate and possibly the overall timing of the software processing.   

MMW_MAX_OBJ_OUT size set to 100:
