TMS320F28069F: InstaSPIN Projects and Labs: the file of proj_lab10a.c

Hello,

I have a question on the InstaSPIN Projects and Labs.

Specifically it is on the file of proj_lab10a.c.

On the code line 112, the global variable of gCmpOffset is declared and initialized as follows:

// set the offset, default value of 1 microsecond
int16_t gCmpOffset = (int16_t)(1.0 * USER_SYSTEM_FREQ_MHz);

However I am not able to find any place where the global variable of gCmpOffset is used.

Is this variable being used in the scope of the project?

Thank you for your guidance.

With regards,

G. Kim
