Update V5.3 / V6.2:
-Added file list and file name editing directory functions. Filenames for all types can be created and filelist displayed.
-Fixed Delta T/freq cursor display not working correctly while in chart mode (did not work after changing chart mode to oversampling). Delta time display over 120 sec. will now display in minutes.
-Fixed FFT to update properly while in hold mode at the slower timebases or after loading BUF file.
-Eliminated the delay at the end of auto reset used in persistence mode.
-Changed VDC meters to read inverted value if in ChA or B invert mode with OS buffers rather than non inverted input value to bring in line with rest of meter displays while in invert mode.
-Changed “save IMG” to “save ROM”. This saves a 512KB binary image of the complete ROM, including bootloader, licence, SYS, all apps, FPGA and logo in .BIN format for restoring device via internal header if ever necessary. Filename is set to ROM_IMG.BIN and cannot be changed. Apparently, some users thought this saved a different kind of “image”. Make sure enough space is available on drive before using this, specially on 2MB devices, if there isn’t the system’s file access functions leave the failed entry behind and uses up the remaining space.
-Removed the requirement for early (2MB) units that CFG files exist before they can be written.
Both versions still leave slot 4 open for an additional program, as well as the area at the start of the second half or the ROM where Alterbios and Pawn store some code.
Some notes on new directory functions:
-Select file type first in file menu to be displayed in list for loading or to edit name before saving.
-Read dir list or access filename edit function with file sub menu (button 4) (file save/load > file number > file type > dir list/name edit) If file load is selected list will be displayed, if file save is selected filename edit function will be displayed.
-Files are listed in sequence found in file allocation table.
-Select file to load in list with left toggle, press center button to load blinking highlighted file. List will scroll up/down when reaching top/bottom. Right toggle can be used to quickly shift list one page up/down at a time for reading large number of entries.
-Last loaded file will remain highlighted in list as reference until extension type in file menu is changed.
-BMP and BUF file selection will advance for quick loading in sequence with left toggle center or previous with right toggle center as with original number system.
-Before saving, edit filename with left toggle to change characters, right toggle to select next/previous character. Press center left toggle to save. Config files can be saved with button 3.
-Characters available are, in sequence: misc symbols > 9-0 > space > A-Z with spaces as default. Short press right toggle center button to reset selected character to space. Long press right toggle center button to reset all characters to spaces.
-Spaces can be left in name, the program will change mid-name spaces to underscores and remove all leading spaces to be compatible with DOS file naming.
-Fully compatible with previous file numbering system, old numbering system still functional.
-Config files selected from list will have name displayed in a vertical row at top left of screen, except in spectrograph and MAP modes. Numbered config files loaded in previous manner will only show number in original place in notification area under Ch C menu.
-Boot config 0 will not be displayed in list, as this is actually a WPT file. Save/reload this in original fashion since it uses the device’s serial number as file name.
-If files are named from a Windows PC, any file name containing mid-name spaces or of greater length than 8 chars will write an additional long filename entry in the Quad’s file table, and while these will be displayed in a Windows machine, only the DOS version with show in the program. These are abbreviated and end with a tilde “~” which will be displayed as a dot in the list, followed by a number. Any other allowed filename characters not in the Quad’s character table will also be displayed as a dot.
Please be aware that the program size for both versions has grown to a point where if loaded onto the wrong hardware version, it will attempt to overwrite some part of the system area. Specifically, if V6.2 is loaded onto pre-HW 2.81 devices, it will overwrite the FPGA, which will require it to be reloaded. If V5.3 is loaded onto a HW 2.81 or later device, it will attempt to overwrite some system code on the second half of the ROM. While there appears to be some measure in the DFU to prevent this from happening, I can’t guaranty this for all DFU versions, and could require the DFU to be reloaded via internal headers. MAKE SURE YOU ARE USING THE CORRECT VERSION FOR YOUR HARDWARE!
