[Discuss-gnuradio] Re: Digitial IO pins

[Jeffrey Karrels]

update.

First off, I had a typo in my email. I meant 'sink.write_io' instead
of what I wrote.  Secondly, I finally was pointed to the schematics of
the rfx900 which helped a lot.  I was unaware of the pin layout
before.  Got it now!

io_tx_15 ---| 1  | 2   | --- gnd
io_tx_14 ---| 3  | 4   | --- gnd
io_tx_13 ---| 5  | 6   | --- gnd
io_tx_12 ---| 7  | 8   | --- gnd
io_tx_11 ---| 9  | 10 | --- gnd
io_tx_10 ---| 11 | 12 | --- gnd
io_tx_09 ---| 13 | 14 | --- gnd
io_tx_08 ---| 15 | 16 | --- gnd


Thanks
