I'm running a regular IIR biquad program copied from adi on the
board but it isn't working. At start it emits a beep then nothing--I can't hear my input voice. When I press the flag for talkthru I can hear my voice. My delay line became filled with FFFFFFs (overflow?) when I halted the program. Below is the equation. I'm using 3 sections and 1 section so it's just small. I disabled the transmit interrupt nesting but still it doesn't work. In the simulator it doesn't have overflows and it's suppose to be a working algo and theoretically it's supposed to work. Why is it not working? Tnx for the previous replies |
