Arduino Mega and GPS MTK3339

Post by buton »

Hi guys i am just wondering
if i use arduino mega with the gps ultimate module will i be able to run it at a faster speed than 1 hz?

how long it take to parse the message with a 8mhz clock? how long with the 16Mhz?

If you're thinking about this one: http://www.adafruit.com/products/790 it can provide updates at 10Hz.

I don't know the exact answer, but eyballing the code in the library, I'd expect it to take well under 100 microseconds at 8MHz. Half that at 16MHz. What kind of processing speed do you need from it?
