GPS data logger

[pascal]

Dear readers,

I have merged two of the topics developed in these pages and made a
nice little data logger for GPS.
It produces directly kml files so that you can take the card out of the
logger and directly see where you have been.

I am sure it may have nice applications. Well, the file system is still not
perfect, but it seems to be reliable at least if you write only to the last
created file.

I will report more detail later.
