[USRP-users] Can only control 1 pin of x310 GPIO

2024-11-19 Thread Will Haftel via USRP-users
Hi, I am having some issues controlling the GPIO on the x310. So far I have only been able to control the output of pin 0. Here are some code snippets of things I have tried: I have these lines before trying to control pins: usrp->set_gpio_attr("FP0", "CTRL", 0x000, 0xFFF); usrp->set_gpio_a

Dear, I am revisiting an issue I encountered earlier. I have a flow that generates pulses with spaces between them continuously. To switch between the RX and TX paths on a single antenna, I tried utilizing GPIO to control an RF switch. Tests were conducted on a B210 and X310. Initially, I used GP

[USRP-users] B210 power and gain levels

2024-11-19 Thread johnhigginsgis
I have few questions regarding B210. 1) Ettus recommends -15 dBm for the max input power. Is this power at the RF ports (i.e. RX-A/RX-B)? 2) Max input power for AD9361 is given as +2.5dBm. Is the difference due to some additional circuitry preceding the 9361 or is -15 dBm just a value Ettus re

Hi, According to the manual, The mask argument can be used to apply value only to select pins, and retain the existing value on the rest. Because of this feature, this API call will incur two register transactions (one read, one write). I think the value parameter should be a hexadecimal number,
