ESP8266 Community Forum

- Fri Feb 12, 2016 5:02 pm #40991 First post; I've read up on a number of projects and interested in a particular application.

I'd like to use the ESP8266 as a usb host to stream data over wifi. I'd like to use it to stream data from an rtl_sdr dongle. The sample rate could be as high as 2MSPS (2 million 16 bit samples). Is this even remotely close to feasible?

1) Can it act as a USB host?
2) What is the maximum reasonable thoroughput?
3) IF this platform isnt reasonable, any suggestions on a reasonable one? Intel Edison is probably the next best platform I am aware of but likely overpowered for my needs. Likewise with RPi.

Thanks,
Philip

I doubt ...

- Sat Feb 13, 2016 1:57 am #41016 What is a feasible sample rate? I've seen projects where it can bitbang NTSC TV (60 MHz)...

Outputing some "templated" NTSC signal using I2S with DMA is one thing, but dealing with an USB software layer to transmit 2 million 16 bit samples to an RTL-SDR dongle is another thing.
