I am going to do frequency scan using C++ code in LimeSDR. How to devide a range of frequency into several pieces? Is it possible to use a loop to devide frequencies and outfiles?

Here is an outline of what you want -

Set The sample rate to 10e6

if (LMS_SetSampleRate(device, 10e6, 2) != 0)
	error();

Step to all frequencies between 800 and 900 MHZ opening a file every 10 MHZ -

Blockquote

for(int k=0;k<10;++k){
    FILE *out;
    char filename[256];
	if (LMS_SetLOFrequency(device, LMS_CH_RX, 0, 805e6+k*10e6) != 0)
		error();
    sprintf(filename,"minute-%08d.raw",k);
    out=fopen(filename,"wb");
    if(out == NULL){
        printf("Could Not Open %s to Write\n",filename);
        exit(1);
    }
	
    ....
	
    if(out)fclose(out)

}
