GPS Ultimate Arduino Support

Post by Brewington »

I am interested in the Ultimate GPS Arduino Shield product 1272. I would like to use it with an Arduino Mega 2560 (or similar). I have two questions:

1) The Tech Description indicates this shield does not work with Mega; only UnoDuemilanove/Diecimila/Leonardo. However, I am seeing posts that indicate it does work with Megas, for example viewtopic.php?f=19&t=155138&p=765577&hi ... ga#p765577.

Does it in fact work with the Mega? Are there restrictions on its use there?

2) Can I log my own files to the SD card, or does that disk only do the automatic logging from the GPS chip? If so, is there a particular library that provides this functionality?

The comment about the Mega probably refers to using software serial in the shield's default configuration. The approach discussed here should generally work for the Mega:

Yes, you can log to the SD card. Think of the SD card as a separate item on the shield. There's a logging example here:

The basic idea is: (1) read/parse info from GPS, (2) write info to file on SD card

Here's the actual writing to the SD card:

Excellent, just what I was hoping.
