Hi,
I am evaluating Imp004 for a Bluetooth audio product. I see that CYW43438 separately supports PCM and STM32F412 supports I2S/PCM, but the Imp004 with the STM MCU and Cypress BT/WiFi combined does not expose any pins connected that can connect to the PCM pins.
Is there any internal pin diagram that shows how STM32F412 is connected to the CYW43438 ? What pins are used and what are not ?
Any help or direction related to the support for Bluetooth audio will be greatly appreciated.
Thanks and Regards,
Subramanyan
