Hello,
I was trying to run this library "spnc042" for PID controller (on TMS570ls0432). And everytime I run it, this or similar error pops up (unresolved symbol __IQmpy, first referenced in ./source/pid.obj). The problem is that none of functions from (IQmathLib.h) header file can be executed. Later on I came up with idea that corresponding *.lib file from (C:\ti\Hercules\Cortex-R4 CMSIS DSP Library\1.0.0\Lib) should be included to CCS (ARM Linker>File Search Path>Add..). But that didn't work as well.. And yes I inserted these defines (User needs to configure "MATH_TYPE" and "GLOBAL_Q" values) in this header file.
I don't know maybe I am missing something, or the tutorials of older versions are not compatible with my CCS 5.3.
So maybe you could create a blank project for this microcontroller and include necessary files and configuration for IQmath (24). And do some few lines of multiplication and addition of floating point type variables (just to make sure, how I should be using those maths)?
