Query on AD1835 CODEC on ADI EZ_KIT 21262 |
|
|
Hello, I am wondering if somebody has any idea that could help me with
a problem I'm having with this kit.
I using it in a magnetic sensor measuring device in closed loop with
48kHz sampling. However I would like to change to 96kHz. The on-board
AD1835 CODEC permits this but I cannot get it to work at the higher
sample rate (my LRCLK disappears). I am using the default AD1835
configuration via SPI code bundled with the EZ-KIT. I've checked the
bit patterns written to the CODEC config registers and they all seem
correct.
I've been in touch with ADC DSP Support. It turns out they could not
get the Assembler code to work either but sent me a C version that
they say works.
However it does not work when I compile and run. We've checked other
things such as Visual DSP Versions and DIP switch settings but all is
OK there.
Has anybody ever had a similar experience as this? Could it be a
compiler issue? |
