R3 1.3 - 24 June 2025

This release allows Touch screen calibration  for older resistive screens in models upgraded from G1,G2 or G3 to G4 and wishing to use Portrait mode (landscape mode calibration was available and valid and could be used for portrait mode but it was necessary to temporary switch to landscape for calibration).
This release adds some new functionality for Video feeds - automatic detection and compensation for different vertical line count between PAL and NTSC camera feeds. Added Video channel selection in Action menu (in case the “video” functional icon is not placed on the screen you can still select video channels in the action menu. Fixed a small bug where additional RDAC CAN for Rotax 912 data was not shown in the diagnostics menu. Fixed a bug related to deleting multiple files at once in a folder using the built in file manager.  Fixed a bug related to using the Sandia transponder as well as Tailbeacon transponder - related to the RS232 serial port.

R2 1.3 - 30 May 2025

This release fixes some issues related to screen updates during a waypoint search.

Added: New function in System Basic Setup functions menu: Install a Linux startup script.
This function allows you to install a supplied or self made script into the Linux /etc/init.d folder. Scripts here are used to start various services and the last script is used to start the EFIS application itself.
Additional scripts can now be added, usually as execute once, that can perform a large range of operations as needed. This is intended for future use and has no current application.
Added: The file manager is now able to install the exp4 EFIS binary executable as alternate means to the boot loader based installation. This can be used if the basic file system support for the Linux EXT4 file system is not able to install a new EFIS application. You simply select the exp4 file in the SD card file manager and copy it to the ROOT folder. In this case the root folder is not actually the Linux root folder but the installation folder for the entire EFIS system (under /efis).

R1 1.3 - 10 April 2025

Dfile.bin custom screen file system is now implemented and functional. Note that dfile.bin files made in previous generations (G2, G3) will not work properly in the G4 due to changes in some component data structures.
You may rename the dfile.bin to one of the following names to make them loadable by EFIS type:

If Portrait mode

exp-480x800.bin, chr-768x1024.bin, mx2-600x1024.bin

If Landscape mode

exp-800x480.bin, chr-1024x768.bin, mx2-1024x600.bin

For Explorer, Challenger and MX2 respectively.

Fixed an issue if “arc” screen component parts (including invisible) are drawn outside of visible screen area. This would cause all subsequent drawing of screen items for a page not to show (Portrait mode only).

Fixed creation of recording file to external SD card (It failed with not enough space on target)

Added a non functional component to screen designer showing a line of dashes in the list of items to draw. This can be used to visually group or separate items in your drawing list.

Added copy of *.jpg and *.mod files in screen files installation function (Install tasks menu), same for deletion of screen files.

Added new function to System Setup -> System basic setup functions. Function to replace the current boot loader (u-boot) on both SSD as well as built in flash memory (the default boot code device).

R1 1.2 -15 January 2025

Mass copy of large files using file manager could result in SD card being detected as removed. Added software filtering of card detect to remove glitches. Changed file synchronization to disk during copy to avoid long wait for Linux file system flush at end of write. Synchronization now done every 8MBytes copied.
Added file name in file copy status display. Added message at end of copy to confirm number of files copied. Added confirmation dialog after selecting target folder for a file copy.
Fixed slight miss-align of vector map display in portrait mode.
Fixed Nearest Airports function when selecting an airport no information was displayed.
