Chapter 11 Using microSD Cards
Project restore is done from the subdirectory specified in ConfigMeFirst.txt
file or the <Micro800>/USERPRJ default folder, if none is specified in the
ConfigMeFirst.txt file. The user needs to ensure that the directory is populated
with correct contents before restoring.
The ConfigMeFirst.txt file is a configuration file stored on the microSD card
that the user can optionally create to customize backup, restore, recipe, and
data log directories. The following sections include information on how to
configure the ConfigMeFirst.txt properly.
Power-up Settings in ConfigMeFirst.txt
On power-up, the controller reads and carries out configuration settings
described in the ConfigMeFirst.txt file. However, the UPD setting also takes
effect when the microSD card is inserted. The configuration settings for the
ConfigMeFirst.txt file are shown in the following table.
IMPORTANT
The Micro800 controller reports a major fault when project backup does not
succeed because the memory card size is exceeded.
