Hi.

I´m developing with LPC1769 using LPCXpresso and I have a problem.
I have downloaded the DSP library from nxp and tested the testbenches that come in it, and they work great. But when I try to add that code into a FreeRTOS project I get the following:
undefined reference to `vF_dspl_fftR4b16N256'.
Do you know how may I fix that?

Thanks in advance

Hi,

thanks a lot for your help, I could manage to fix the problem. One more question, where can I get the software examples for App Notes AN10934 and AN10943?

Thanks in advance.

Hi!

Sounds like you may need to add the library file from the CMSIS DSP library into the LPCXpresso project. This can be done in the project Properties dialog, under the C/C++ Build group, Settings sub-option. Then you will get another treeview of options. Now select "Libraries" under "MCU Linker" and make sure the DSP library is listed.
