Not sure if this is the appropriate forum to post in, but I'm working on a project where I'm wanting to transmit PCM G.711 audio between two microcontrollers. I have experience with the ATMega2560 and used a XBee module to wireless transmit between microcontrollers.
Would a microcontroller like the ATMega2560 be capable of transmitting PCM audio? I figured it might not be since the specs might be too limiting in order to do what I want. I've tried researching this online and I've struggled to find a definitive answer. And if possible, would I need to implement code utilizing a protocol specialized for audio like I2S? I've used UART for transmitting data and it seems that UART wouldn't be able to handle audio data.
