Rec and play on LyraT-MINI
Posted: Tue Feb 18, 2020 5:29 pm
Hi,
I have been using a LyraT for a few months with ESP-ADF for my project with success.
Now i test the LyraT-minni version, but i have problem when i try to use the same code logic that for the LyraT.
I use 2 pipelines, one for the record, one for the playback.
But for now, it is impossible to enable record and playback. I don't want use both together, but one after the other, but impossible.
If i enable the record, le playback is not available.
If i enable the playback, the record is not available.
Of course i wish use both. How can i do that ?
This issue is due to the technical architecture of the LyraT-mini.
- LyraT 4.3 : https://docs.espressif.com/projects/esp ... l#overview
- LyraT-mini 1.2: https://docs.espressif.com/projects/esp ... #overview
I think i need use audio_hal_ctrl_codec only for one pipeline, playback for example, and use DAC of ESP32 for the other pipline. Like in this sample : https://github.com/espressif/esp-adf/tr ... ay_mp3_dac.
Has anyone ever had this problem?
Could my approach be the right one?
Thanks for your help
