I currently got a adsp 21489 EZLITE, and want to configure the sample rate from 48khz to 8khz in the example AD1939 C Block-Based Talkthru code.
From the datasheet of ad1939, it claims that it supports 8k-192khz sample rate. And I found this article in previous discussion: AD193x family - supporting Sample Rates lower than 32 kHz
I tried to modify the code in init1939viaSPI.c:
Setting the clock control registers to the following:
(AD1939_ADDR), CLKCTRL0, 0x81,
(AD1939_ADDR), CLKCTRL1, 0x03,
Unfortunately, it doesn't work for the board. Any pointer or guide to help me how to configure the sample rate to 8khz. Thanks a lot.
