Hello HifiBerry-Community
I want to add an I2S-Output to my "Hifiberry DAC+ DSP" in SigmaStudio. But i dont know which output i have to add.
The P3 "eDAC" should ouput the music which is active on output 0 and 1 (Analog Out L/R).
As far as I know, I can use this output:
So how can I write an I2S-signal with a L/R-signal to SDATA_OUT0?
Thanks a lot for an inputs! (And sorr for my english...)
The EDAC output is the one that's already in use by the onboard DAC. With the existing profiles, you already have the I2S data on this header.
Ok, one step closer to the solution...
When I connect my ESP32 with a running I2S code, I hear only strange noise on analog output (only when play music). I cant judge, if the data received by ESP32 is correct...
As written in I2S header (arduino-example), I have wires connected as following:
- SCK/BCLK from PIN5 (eDAC P3) to GPIO14 (ESP32)
- SD/DATA from PIN6 (eDAC P3) to GPIO26 (ESP32)
- WS/LRCLK from PIN7 (eDAC P3) to GPIO25 (ESP32)
I would say, that no matter which code to read out I2S on ESP32, Hifiberry should be able to make "nice" music at the analog-output?
