  1. Re: ASM ERROR : Linker Error "Warning: resource version (1.30) does not match!"

    Tim, it's late here. Can you provide a complete program so Les can test compile rather second guess the full setup.

  2. Re: ASM ERROR : Linker Error "Warning: resource version (1.30) does not match!"

    Tim, I also had a problem with cread32 as I was trying to bring in a float. I ended up using cread and put the problem down to me. I should have reported it at the time.If Les requires it I could...

    Lester, I'm getting not so tasteful ads. In the banner "Hot chats", Find ladies, Dating site.
    Reading a post in the Lounge I copped a dating site with an image.

    Re: Suggestions for pic microcontroller

    If you buy them from Microchip Direct they are dirt cheap but freight is a killer if you only buy a small number.
    There is also a chip select facility on the site to help you make your choice.

  8. Re: Some translation mathematical difficulties

    Hello again Yves,
    I'm on a roll with a quiet Boxing Day holiday.
    Here's how you could do it using a table.
    I couldn't get Cread32 to work, may be a problem with it but Cread worked OK.
    This is...

  10. Re: Some translation mathematical difficulties

    Looking at your graph I think you'd get away with 40 data points. I usually write a simple Delphi program to create the points.
    If you want I could produce it for you. Delphi can generate very...

    Memory bit wobbly nowadays but I think Les said "end" is redundant. As George said, the compiler knows when to stop.

  23. Re: using a gps to claculate distance and direction over small distances

    Hi George,
    I can't find if I created a BAS file but I did experiment in Delphi during 2012. I have attached all the files for the project although you probably only need the pas file.
    I can't vouch...

    Sorry George, I completely forgot to look up my short distance version. It just used simple triangulation and is better for close in. Will look this morning.

    Re: Why a delay in TX power up?

    Seems to point to the TX being slow to fire up.
