I2S Output Function Lost Even When RAM and Instruction Usage Are Within Range
Hi Everyone, I have verified the hardware with a smaller amount of RAM and fewer instructions, and I’m sure the environment is fine — the I2S output works normally in that case. However, after I added

finding solution for auto switching input source if input level reaching threshold
Dear ADI Teams i have some idea,if the volume is low then input source is the loudness one for bassboosted,and if high volume is detected then the input will switch to the original input for easier co

adau1701 Setting up parallel delay modules causes severe comb filtering issues.
As shown in the image, I split a single signal path into three parallel paths and inserted a delay module into each downstream path. When I set the value limit to 512 samples, the result was that even

Fractional Delay Buffer Splitting Problem
When I create a project and use two fractional delay blocks that sample the same signal, the compiler shows that buffer space is reserved only once—which seems logical. I want to use 48 fractional del
