question: VS1053 + MERUS audio, how to connect to each other?

Open dibalavs opened this issue 1 year ago • 0 comments

Hello Try to use next chain:

ESP32 -> [SPI] -> VS1053 -> [I2S] -> MA12070P

So digital output of VS1053 connected directly to MA12070P. But as a result, I hear silence.

How to connect them together?

VS1053 produces BCKL - 1.5Mhz with 16bit width may be it is not enough for Merus Audio? Also I tried to use MCLK from VS1053 (it generates 12.288 Mhz) to Merus, without no success.

If I connect Merus directly to ESP (BCLK = MCLK = 2.88Mhz and 32bit width) all works.

Does anybody is able to connect this 2 chips to each other?
