1. How do we change the DAC settings on the DM642
board ?
The method we tried out to change the Sampling rate
from 48 KHz to 8 KHz on the
TLV320AIC23 chip is as follows:
a. We changed the following line in the file
"..\ti\ddk\include\aic23.h" from
#define AIC23_REG8_DEFAULT
AIC23_REG8_48KHZ
to
#define AIC23_REG8_DEFAULT
AIC23_REG8_8KHZ
b. Then we rebuilt the project
"..\ti\ddk\src\audio\evmdm642\evmdm642_edma_aic23_64.pjt"
using Code
Composer Studio (CCS).
2. Even after the changes done in 1.a and 1.b were
carried out, we could not make out
any change in the sampling rate of the output audio.
Regards,
Mayank
