problem regarding conversion from float to Q15
megha daga - May 16 2006
Hi
I am working on a code to convert float to Q15. I am working with just 4 samples. I have stored the 4 coefficients in coeff[4]. the converted value is going to get stored in... 542 and 20

Hi
I am new to group and to 54x. Please guide.

Dear Jeff
I did following things:
First: Working
long rx_wait = 0;
long tx_wait = 0;
while (!PEP5416_AIC23_read16(hCodec, &bufferrcv[i])) rx_wait++;
while (!PEP5416_AIC23_w... Re: [Fwd: Re: code working on simulator but not on device?] [2 Articles]

Suggestions:
1) Comment out Preemphasis() for now, during debug.
