Hi PJ,
Could you say more about these two methods?
Analogue Audio: I don’t think the ESP32C3 has a DAC, so we’d be going directly from a GPIO pin with a PWM tone as I understand it. What kind of circuitry/components would follow that?
For I2S: I was thinking of using the methods of DronBotWorkshop. My question regarding this is: would it be possible to use a file from the flash memory instead of the SD card?
