4) Right-click on the LOG object called LOG_system. From the pop-up
menu, select Properties.
You see the properties dialog for this object. At run time, this log stores
events traced by the system for various DSP/BIOS modules.
5) Change the buflen property to 512 words and click OK.
6) Highlight the CLK object called dataIO_CLK. Notice that the function
called when this CLK object is activated is _dataIO. This is the dataIO
function in volume.c.
Note: Underscores and C Function Names
This C function name is prefixed by an underscore because saving the
configuration generates assembly language files. The underscore prefix is
the convention for accessing C functions from assembly. (See the section
on interfacing C with assembly language in the
TMS320C6000 Optimizing
C Compiler User’s Guide
for more information.)
This rule applies only to C functions you write. You do not need to use the
underscore prefix with configuration-generated objects or DSP/BIOS API
calls because two names are automatically created for each object: one
prefixed with an underscore and one without.
