Boot menu
Multiple projects can be stored on the integrated SD card. The project which is started automatically is defined using the "start.emc" file. To load a different project, the start file need to be updated, or on touch enabled panels, a project can be selected via the boot menu:
Version -TP: When switching on the device (or after hardware reset), touch and hold the screen. Release the touch after the message "Enter Bootmenu" appears. Touch the panel twice within one second ("double-click") to enter the boot menu.
Version -TC: When switching on the device (or after hardware reset), wipe over the touch panel several times in short interval.
To avoid mis-use by the operator, the boot menu can be deactivated. For this purpose, an empty file named "bootmenu.off" must be placed in the root directory on the SD card. This can be done using mass storage mode and Windows Explorer to transfer the file, or directly via uniTFT commands:
#FWO</bootmenu.off>
In addition to project selection, the boot menu offers the option to start test mode, or to display information about the module. It provides the version, protocol status, baudrate, SPI mode, I²C bus address etc
Also the Mass Storage Mode can be entered in boot menu.
To prevent the operator from selecting Mass Storage Mode, this entry can be removed from the boot-menu. To deactivate Mass Storage Mode, there must be an empty file at root level called "usbmsc.off". This can be done by uniTFT commands like that:
#FWO</usbmsc.off>
