Relating to the description of the GPIO:
https://files.ettus.com/manual/page_gpio_api.html
Should the code example on this page, which has the following code:
// finally, let's set up GPIO6 as we described above
usrp_x300->set_gpio_attr("FP0", "ATR_0X", 0, AMP_GPIO_MASK);
usrp_x300->set_gpio_attr("FP0", "ATR_RX", 0, AMP_GPIO_MASK);
usrp_x300->set_gpio_attr("FP0", "ATR_TX", 0, AMP_GPIO_MASK);
usrp_x300->set_gpio_attr("FP0", "ATR_XX", 0, AMP_GPIO_MASK);
actually be:
// finally, let's set up GPIO6 as we described above
usrp_x300->set_gpio_attr("FP0", "ATR_0X", 0, AMP_GPIO_MASK);
usrp_x300->set_gpio_attr("FP0", "ATR_RX", 0, AMP_GPIO_MASK);
usrp_x300->set_gpio_attr("FP0", "ATR_TX", 1, AMP_GPIO_MASK); // Should it be a
1?
usrp_x300->set_gpio_attr("FP0", "ATR_XX", 0, AMP_GPIO_MASK);
for setting up GPIO6 to be high only when transmitting? If not, then I'm not
understanding what the code is really doing to get GPIO6 to be high when
transmitting.
Thx.
