Hi.

If  i want to use PDM_Filter_64_LSB() function from pmd_filter.h in my program or just build the ''Audio_playback_and_record'' project, i got a 'undefined reference to PDM_Filter_64_LSB' error. I guess i have to use the libPDMFilter_GCC.a file somehow. How can i attach it to my project in Atollic TrueStudio? Please help! Thanx.

    Presumably you'd just Add it to the project, or drop it in, presuming you have a version that permits external libraries, which the old Lite version didn't.

    Hi, I'm using Version 3.2.0 Lite and i'm getting undefined reference to PDM_Filter_Init when I include pdm_filter.h. I have the libPDMFilter_GCC.a in the same directory as pdm_filter.h and main. Do i have to add another reference somewhere? Thanks,

    Never mind, found it at build settings, tool settings, c linker, libraries, add PDMFilter_GCC...
