Hi, Thank you for your quick reply. I tried to used that UHD example by doing several changes, but when I going to change data direction register (DDR) by "usrp->set_gpio_attr(gpio, "DDR", ddr, mask); " command. But I got following error massage,
Error: LookupError: Path not found in tree: /mboards/0/gpio/DDR I have Ver 6 USRP B210 green board and 3.8.005 UHD version. I am waiting for your help. Thank you in advance.
