TI's PDFs seem to point out the fact that the DSPLib was written for the 62XX series DSPs. I have attempted to compile in the DSPLib, and have had no luck, I can't even get a clean compile. Do i need to recompile the DSPlib for the 6711? I'm aware that most of these are definitly newbie questions, so any help I can get is appreciated. Thank you! --Matt

The dsplib does not seem to use any instructions specific to 67XX core; so I suppose it does not need to be recompiled. C62XX instructions are a subset of C67XX. What kind of error messages appeared during the compilation and for which routines? Regards, Andrew > --Matt

As per page 15 of the DSP Lib reference manual: (http://www-s.ti.com/sc/psheets/spru402/spru402.pdf) Added dsp62x.lib from ti\c6000\dsplib\lib and rts6201.lib from ti\c6000\cgtools\lib to the project, via the standard method. Should i be using rts6700.lib? I assume the other 6700 series lib, rts6700e.lib is for use with the emulator, which I do not have. also added "dsp62x.lib;rts6201.lib" to the include libraries box under the linker tab of the project build options, and c:\ti\c6000 \dsplib\lib to the library search path of the linker tab under build options for the project. Ran a build all: got 1 warning ## start error ## <Linking> >> C:\ti\myprojects\mss - audio\audiocfg.cmd, line 197: warning: (.args) not found Build Complete, 0 Errors, 1 Warnings, 0 Remarks. ## end error ## Lines 196-200 of the audiocfg.cmd example read: .args: fill=0 { *(.args) . += 0x4; } > SDRAM No real idea what this means, but the cmd is a generated file. Is there something I missed somewhere in the config tool? It's just a warning, so I continue. Anyway, now to doing something simple like passing an array of numbers to the maxval() routine. now add C:\ti\c6000\dsplib\include to the include search path (-i) under compiler|preprocessor, so that I can do an #include <maxval.h> I added #include <maxval.h> in the top of audio.c then, I added the following declarations in void main() short maxout; short stuff[4]; and this code to populate/call maxval. stuff[0] = 2; stuff[1] = 5; stuff[2] = -4; stuff[3] = 3; maxout = maxval(&stuff[], 4); Now my C might just be rusty, but DSPlib reference for maxval says: short maxval(short *x, int nx) where *x is a pointer to the input vector, the size of nx. I'm passing a pointer to the array 'stuff' and its size (4). I get the following error: "audio.c", line 57: error: expected an expression line 57 is the maxout = maxval(&stuff[],4); Like I said before, any help would be appreciated.

The easy one first, you may want to call maxval as any of the following maxout = maxval(stuff, 4); maxout = maxval(&stuff[0], 4); maxout = maxval((short *)&stuff[0], 4); maxout = maxval((short *)stuff, 4); On the runtime support library issue: the audiocfg.cmd uses rtsbios.a67 RTS library (-lrtsbios.a67 somewhere in the middle of the file). .args is a section definition, for info on linker sections see SPRU186 Assembly language tools UM. I never ran into such an error though ...

I am currently trying to interface to the 6711DSK through the HPI port. Does anyone have any example host source code written in VB? Thanks in advance Dave Cranidge
