Re: [Discuss-gnuradio] toggling LFRX gpio pins

[Nemanja Savic]

After some time I maybe realized how this thing works, but I don't know jow to call correctly methods from dboard_iface:

def get_pin_ctrl(self, *args, **kwargs):
        """get_pin_ctrl(self, unit_t unit) -> boost::uint16_t"""
        return _uhd_swig.dboard_iface_get_pin_ctrl(self, *args, **kwargs)

ef get_gpio_ddr(self, *args, **kwargs):
        """get_gpio_ddr(self, unit_t unit) -> boost::uint16_t"""
        return _uhd_swig.dboard_iface_get_gpio_ddr(self, *args, **kwargs)

or any of these methods that have *arg and **kwargs. When I call like this:
iface = usrp1_src.get_dboard_iface()
print iface.get_pin_ctrl(uhd.dboard_iface.UNIT_RX, 0)

I get following error:

Traceback (most recent call last):
  File "lftx_io.py", line 31, in <module>
    print iface.get_pin_ctrl(uhd.dboard_iface.UNIT_RX, 0)
  File "/usr/local/lib64/python2.6/site-packages/gnuradio/uhd/uhd_swig.py", line 1691, in get_pin_ctrl
    return _uhd_swig.dboard_iface_sptr_get_pin_ctrl(self, *args, **kwargs)
TypeError: dboard_iface_sptr_get_pin_ctrl() takes at most 2 arguments (3 given)

Hi guys again,

I have designed small RF frontend using TI's cc1000 transciever. Since the transciever need to be configured using external pins, I need to be able to toggle gpio pins on my LFRX. I have found that I should use dboard_iface which is available in python via swig. However I have several questions:

How should I address my board, since there are 4 possible slots, and onlt 2 values of type unit, UNIT_RX and UNIT_TX.

As far as i can see, every uhd source has method get_iface, does this anyhow concerns me?

Thanks again,

Nemanja
