I just got a stalker last week because I want to build a race timer for my running club. It looks like it’s just what I need but …
I cannot get the micro SD card to log data, using the code provided in the datasheet. It flashes the light in the setup routine when it makes the initial call to FileLoggger::append but never returns.
The card is a Lexar micro SD of 2GB capacity formated as FAT 16 with a file called data.log - this never gets any data stored in it.
I suspect that it is something to do with the card, but unless I can get another type of card to try I don’t think I will make progress now.
Is there a list of problem/good cards to use with the stalker?
Does anyone have any ideas about how to debug this, given the fact that the append call does not seem to return?
Many thanks for any help anyone can give me.
