esreis: No I dont think I can fit the float lib without significant rework.
On both boards there is a Mega88 that have 8k bytes program space to use. Only adding radians function and math.h adds 1588 bytes. And adding bearing function takes another 2844 bytes. Adding distance_between function uses another 664 bytes. Totaling at 5096 bytes! Thats more than half the program space! I need to find a way to do the calculations using only ints. Edit: Compare with the arduino that have 32K flash... Hmm...

esreis: Yes, a atmega328 would be nice...
What if we skip the fact that the earth is round? (Worked for people a long time ago. ) The difference in length for less than 10 km must be really small. Need to calculate a bit on that... /Calle

uC change

Yes, if the footprint and pinouts are exactly the same, it would be great to have a larger uC on there, which I can switch out in a few minutes.
