Data Logging sketch for Mega

[fat16lib]

I have posted a sketch, MegaLogger.pde, that will run with no jumper wires on a Mega Arduino with the Data logging shield.

It will time stamp files and logs the data, time and analog data.

It uses software I2C and SPI on the Mega. It also runs on a UNO and uses hardware I2C and SPI.

I have included the libraries I used with the sketch.

The file is AdafruitMega20120329.zip located here http://code.google.com/p/beta-lib/downloads/list.

Yep it works great and can be very fast if you want!

NICE !!!!!!!

Not only does it work perfectly, it's easy to use and understand! Thank you for your hard work

This does run well, I am using it to collect environmental data.
One question – the sync() function is not called anywhere in the code.
I have read that this must be called every time data is written to the card.
I don’t completely understand CD card programming but other examples I have seen do use the sync() function.
Possible it is called by the logger object, does nayone have any comments.

Thank you

The sync() function flushes any partially filled buffers to the card. Otherwise, the data is only written when the buffer fills up. Calling sync() on every write prevents loss of unwritten data, but it takes time and will limit your max logging speed.

i am trying to your sketch to run on the DUE.

I keep getting:

what am i doing wrong?

Thank you Thank you Thank you.
For a long time I was trying to make my mega1280 to use my ethernet and sd card ad the same time using SDFAT just like with my UNO and with your beta library, everything work fine now, no problem at all...
