Tim, you can attach a stream tag to the sample on which the GPIO should go high or low. The tag key should be "tx_command". The PMT format is the same as if you were sending a message to the block. Tags get processed first (before samples). That does mean that you need write to a block that checks

The code is hard to read in the formatting that came through. But some comments: - start_of_burst is not actually required, that's true. It's a remnant from the past. - You don't send a zero after EOB, rather, you need to attach the EOB to something. In your example, you could also attach EOB to th

[USRP-users] Toggle GPIO above sample level

2024-10-24 Thread Tim Vancauwenbergh
Hello, I have a GRC flow which generates a series of pulses. To suppress the LO leakage from the transmitter being on while sending samples with value '0' I want to use a method in GNU Radio Companion to Toggle a GPIO pin. The pulses are always the same, but I cannot use repetition using RFNoC as
