Hi,

I am having quite a bit of trouble with a task I have to do, I was wondering if anyone would be up to helping me over an im (preferably msn), as it's probably easier to do it that way. To give you a brief intro to the task I have to get a GPS Receiver to display the time in seconds on two seven segment displays. A link to the task sheet is below. If you think you could help me out/help me fix my code or help me design a better way around it, I would greatly appreciate it.

Here is the task: http://img181.imageshack.us/img181/4875/gpstaskja3.jpg

Thanks

i'll just place some more info in here i've done some code, the thing is that it has to fit into a 64/32 chip MACH4A5 (by lattice). at present i'm getting this error...

Code:

Also I have posted my code onto this pastebin if someone could help me. I have put a code to get into it for various reasons, the code is cc2510. Here is the link http://www.pastebin.sk/en/6648/ would really appreciate some help with this.
