Chapter 10 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.
Powerup Settings in ConfigMeFirst.txt
On powerup, 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.
The Micro800 controller reports a major fault when project backup does
not succeed because the memory card size is exceeded.
ConfigMeFirst.txt Configuration Settings
Setting Takes Effect On... Description
Firmware update settings
[FWFILE] Powerup File path location of the firmware revision on the
microSD card. The default location is in the
following format:
firmware\<catalog number>\<filename of firmware>
[FWDOWN] Powerup Sets whether to upgrade or downgrade the
controller firmware from the current revision.
0 = Upgrade firmware; 1 = Downgrade firmware
IMPORTANT: Firmware Upgrade will happen if
[FWFILE] setting points to a newer version of
firmware file compared to current firmware in the
controller, irrespective of [FWDOWN] setting.
