ADAU1451 EQ ADDRESS
Hi,
I have a problem when load the EQ parameters on ADAU1451.
I build a 28 band EQ. T
The first parameter address is: 0x002B //DM0
The second parameter address is: 0x600E//DM1
The third parameter address is: 0x0030
The fourth parameter address is: 0x6013
Interleaving addresses.....and goes on, until 28 EQ.
When i load parameters into addresses 0x002B, 0x0030, ....,0x0071 there is no problem. At DM0.
But when i try to load into 0x600E, ,0x6013,..., 0x604A is a problem, the audio begins click and distortion comes.At DM1.
The parameters are the same and load in direct write during inicialization, i don´t know why. Am I missing any thing?

Hello,
I assume you are using the safeload function?
What version of the compiler are you using?
Can you attach the compiler output report so we can see all the usage?

During inicialization i mute DAC and do a direct write, then i unmute DAC. When the parameters are changed after inicialization, i use safeload registers for every block that is possible.
The sigma studio version is 3.14.
Hello,
Can you attach your project so we can try to replicate this.
I also need to know what sampling rate you are running the hardware on? Not just the SigmaStudio setting. What is the MCLK frequency?
Thanks,
Dave T
Crystal 12.288MHz
MCLK = Base_Fsx2(24.576Mhz for 48kHz)
Start Pulse = Base_Fsx2(96kHz for base sample rate)
Serial input port SDATA_IN0 -> Sample Rate = Fsx2
Serial output port SDATA_OUT0,1,2,3 -> Sample Rate = Fsx2
How can i send the project only to you?
For now the problem was solved.
I just drag and drop the 28 EQ blocks, the address are all inside DM0.
Only when use grow algorithm the DM1 problem shows up...
