2010-10-19 Thread bobb
We're exploring the possibility of monitoring the overrun/underrun status via the USRP2 UART. I'm curious to learn what approaches people have taken to do this (e.g., connect the UART to a logic analyzer, use a level shifter -> RS232 -> host serial/USB port, etc.). I'd also like to know wha
