I've worked with a DSP project where I needed to print the values of functions out. What I did was added functions to the ini file listed at the Options for Target - Debug tab's Initialization File field. If you don't have one, just use a text editor to create it and save to as file_name.ini. The functions acted as wrappers for the stdio printf. There was an array, output[1023], being used with fft functions that I was interested in. In one context the first 512 elements were interesting, in another, all 1024 were interesting.
.ini contents:
FUNC void print_output512(void){ unsigned int i; printf("BEGIN OUTPUT 512\n"); printf("BEGIN OUTPUT 512\n"); printf("BEGIN OUTPUT 512\n"); for(i = 0; i < 512; i++) { printf("%f\n",output[i]); } } FUNC void print_output1024(void){ unsigned int i; printf("BEGIN OUTPUT 1024\n"); printf("BEGIN OUTPUT 1024\n"); printf("BEGIN OUTPUT 1024\n"); for(i = 0; i < 1024; i++) { printf("%f\n",output[i]); } }
If I recall correctly, you then compile and in debug use the command INCLUDE file_name.ini. Then you can set a breakpoint where your interested in viewing values and call the functions by name in the command window. You can copy and paste from here.
