Re: [time-nuts] Lady Heather on low power CPU/Linux?
I use this on Linux: cd ~klotz/.wine/drive_c/Program Files/Heather wine heather.exe /IP=localhost:45000 /TW=250 I use Ralph Smith's tboltd so heather connects to a TCP port, but you can also just give a COM port to connect on the line above. The /TW=250 gives reasonable performance without tremendous CPU usage. http://wa5znu.org/2011/08/tbolt/ Leigh/WA5ZNU On 02/22/2012 04:45 PM, Mark Sims wrote: The roots of Lady Heather lie in a program written in the mid 1980's for controlling a Magellan GPS board (a multiplexed single channel receiver - Bruce has it now).

If I have not just bought one of those $40 Rubidiums I'd be working on this. LH could stand to be refactored so it coulld run on low powered PCs or even an Arduino type micro controller. My idea was to divide the work over three processes 1) very light weight and only connects the t-bolt information to a network socket. no procesing. This could run on a uP if needs be. Written in plain ANSI C and very portable 2) and engine for calculation and control. it has no user interface at all and runs as a background task. multi-platform unix/linux/Windows/mac 3) User interface. Talks to #2 above. There is no reason why there can't be several of these each with a different look could be native or even a web page. I really don't like having to run Windows just for this lone program and even then the screen design and over all user interface is primitive, even by Windows standards The way forward, if I get to this before some one else does is to start with small funtionality in each of the three programs, perhaps just temperature monitorring.

Re: [time-nuts] Lady Heather on low power CPU/Linux?
FWIW, I'm running an Atom D510 motherboard with an 8 port serial card. I'm using Windows 7 and VNC for remote access (the machine runs headless). I am regularly running LH v3 beta, TimeLab (reading PPS data from a TIC), TAC32, and GPSCon each on its own serial port simultaneously without any problems. I normally only have two of the apps maximized, but don't see any significant lags. The only problem I've had was the dreaded Microsoft serial-mouse-on-bootup issue. If you think it's fun watching one phantom mouse scribbling on your screen, wait until you try it with four! (BTW -- apparently, under Win7 the old switch to turn of serial mouse detection no longer works; all you can do is go into the control panel mouse settings and disable each phantom serial mouse separately.)
