Hello All,
i am am using SoDaRadio on a Raspberry Pi4 with B200mini. Operation is
confirmed, but w/o GPIO because original software is not enabling the
use of GPIOs for B200mini.
Now i want to make use of the GPIOs to trigger switching a TX/RX relay.
I am sending this:
// GPIO PIN 1 is used for TX/RX Control manual (no ATR)
// GPIO PIN 2-4 are used for Band Setting manual (no ATR)
// -> 0x0F is the mask , 0x0 -> manual (0x1 = ATR)
usrp->set_gpio_attr("FP0", "CTRL", 0x000, 0x00F);
// setting Data DiRection 0x1 = output
usrp->set_gpio_attr("FP0", "DDR", 0x1, 0x00F);
// reset GPIO pin 0,1,2,3
usrp->set_gpio_attr("FP0", "OUT", 0x000, 0x00F);
I would expect that GPIO pins 0,1,2,3 are set to 0V, but alle PIN are
high as after poweroff.
Need your help.
