Streaming Audio with FRDM-K66F

Hi,

I would like to have high quality mono audio (16bit, 48kHz) simultaneous receiving & transmitting with the FRDM-K66F via Ethernet to another FRDM-K66F. I'd be using the codec on the board not the ADC. I'm not looking for code to do this, but simply want to know if anyone's been able to get something like this working. I'm asking because I wonder if the K66 can handle this much workload. What has your experience been like?

Thank you very kindly,

Andre.

Hi

- 80MHz K22 with 48k/samples/s via USB doing real-time floating point FFT and displaying: https://www.youtube.com/watch?v=n-GABeILGV8&t=3s
- 120MHz K64 doing 400kHz 16 bit ADC input and real-time floating point FFT requires about 30% of its power.
- 120MHz K64 receiving 16 x 24 bit audio channels at 8ksamples/s, calibrating, and sending to PC host via UDP (Ethernet) about 20% CPU load and sleeping in low power mode for 80% of the time

180MHz K66 receiving 48k x 16 bit samples per second and streaming via Ethernet: it will be quite bored.....so nothing to worry about.

Regards

Mark
