No Indication of Overflows in GNU Radio #34

Open 777arc opened 5 years ago

777arc commented 5 years ago

I'm using the Pluto in GNU Radio, and I noticed that when I'm running at a high sample rate, like 60M, there is no indication of overflows. I'm assuming there are overflows considering USB 2.0 can't handle 60M IQ samples per second, and the specs say the Pluto can only go up to 20M. Let me know if I'm missing something here.

The notification mechanism has not been merged yet for underflows/overflows, but the functionality exists here if you are curious: https://github.com/analogdevicesinc/gr-iio/tree/underflow-overflow-support

Ah thanks. I would get it merged into master as soon as you can because the first thing a lot of folks getting their first Pluto are going to do is check how high a sample rate they can realistically get on their machine. You can close this issue if you want, although it's a good way to advertise this feature branch.
