I have never before programmed on a DSP, so i might have missed something obvious, but here is my problem:
I am trying to implement a FIR filter in the Block Based Talk Thru example for the 21369.
My delay line (temp) and my FIR filter seems to work when i use my debug code.
But when i run the program with an input whitenoise the output is not filtered as it should be.
I think the problem has to do with the numberformat used in the unsigned int, negative numbers, and the DAC.
Any help will be greatly appreciated.
P.S. Pardon broken english, it is not my native
This is the code from the blockProcess.c
