Hi All,
I have an interesting little question, I have the following in a design for an ADAU1452
As you can see it simple flashes a "heartbeat" LED to show that the processor is alive with a cadence of 11000000. Can anyone think of a way that I can control the GPIO pin so the Cadence can be 10100000 or any other pattern that could be loaded to indicate various status? A typical logic design would just use an 8-bit shift register but I can't work out how to do it in SigmaStudio.
Another question:
Is there any way to compare the Core clock with the incoming clock on one of the SDATA input streams? This would be to determine the sample rate. The Core clock is always 12.288MHz but the incoming sample rate could be 48kHz or 96kHz and I would like to be able to determine which it is.
thanks for any help or suggestions
