Hi there, I got a DAC (MAX541CEPA+) that only takes SPI. I was wondering how can I adapt this library to work with SPI instead of I2S. Many thanks |

I suggest that you have a look at my solution which is supporting spdif: https://github.com/pschatzmann/arduino-audio-tools/tree/main/examples/examples-basic-api/basic-a2dp-spdif Please note that you receive the data as int16_t with 2 channels, so you will need to convert it to a mono before writing it out. I assume you know how to write the data to your DAC because I can't help you with that. |
