Cautions with _write_oe

Hi,

I have the TV_RX board in slot B and Basic RX in slot A of the USRP. I
am
trying to get the raw A/D data that comes into the FPGA, out on the
daughter
card connector. I would like to use the 16-bit general purpose debug
pins
from the FPGA on the connector on Basic RX. However, I’d like to be
careful
before I write to the direction register using the _write_oe given that
an
improper setting can cause damage. My question is whether I can have
both
TV_RX and Basic RX boards plugged in, while I use the _write_oe? If yes,
what is the precaution that I have to follow? Any suggestions
appreciated.

Thanks,

Nirali P.

You are safe with both the basic boards and the tvrx, since they don’t
drive any of the pins.
