i want to control a external switch array via LimeSDR-gpio dynamically. One of my first step was to change the value of FPGA Register 00C0 to FFFE to get tx activity on J12 header (Pin 0).
Iḿ using vectors n gnu-radio of some “ones” and “0” to get a periodical tx-burst and was also able to receive signals (two channel MIMO-mode). Unfortunately the J12 Pin 0 is always “high” now. as long as gnu radio is running. Is there a posibility to enable AND disable J12 pin 0 exactly with tx-representation? I have burst times of ~500 ns and periods of ~1-7 µs.
If there is no possibility to do that in gnuradio, i would appreciate a lot to get a basic tx-example (cpp or python) with periodically tx on and off, which is correctly represented by the JPIO-Pin.
Thank You in advance
