Jun 27, 2023 · At the same time, I also input the same 10Mhz clock signal on the clock input port. The older way of checking using hackrf_debug will not work correctly on some hardware revisions. You can also link their clocks via the clk in/out ports you can get very synchronized signals. 4", which ensures that no HackRF header pins are occluded by the module. And there are external devices that generate the 10 MHz reference from GPS for precisely this purpose. And CPLD: hackrf_cpldjtag -x hackrf_cpld_default. Using the serial number of the HackRF One to be triggered, use hackrf_transfer-H to set up a triggered operation. Firmware from the HackRF release/repository is different than the original CCCamp firmware and only supports operation as a USB SDR peripheral. Usage Use hackrf_info to discover the serial numbers of both HackRF Ones. Actual behaviour. This requires 2022.
