Could you add a PPS output so the program can be used as a time source?

    Hi

    That might not be difficult in a hardware device. For software however, what would the output signal be?

    I'd like to have a PPS on RTS. Just a quick pulse every second would do.

    That might be feasible. I'll see if it can be incuded in next revision of the software.

    Hi,

    Also looking for a 1PPS output on RS232. Are you planning such a solution?

    I am afraid not for now, since my time at present is limited and my use of gpsfeed+ not so frequent and I never had a use for an 1PPS signal. But I might try to implement it if I need to spent some time on gpsfeed+ code in the future. I cannot make a commitment though.

    What would be the pin you would expect to see the 1PPS signal on? Searching for GPS 1PPS I find that its implementation varies with the manufacturer of the GPS. Some have it on DCD, others on DSR or on CTS or even RI. Do you have an 'educated' preference about this?

      I also have look at which pin to use previously. What I observe is using DCD is more common. But I can change the connection accordingly. Thank you for the info.
