There have been some threads on this a year or so back where Pjotr shared his successful integration of the ESS Controller board (developed by Ian JIn in Canada) with the Khadas Tone Board (KTB). There is a photo of his end result on this forum. However, the connections discussed in that post don't seem to correspond with the signals available on the connector used by Pjotr. I wondered if anyone else had done this and if so, which signals they picked up from the Khadas board to pass through to the ESS Controller. In Ian's documentation he specifies using SCK and LRCK to trigger this on-board analyzer. LRCK is available but the only other similar signals I can see available on the KTB are MCLK and BCLK. Can anyone help me on this?
