UNO2IEC Change Log
================================================================================
2014-05-08:
* Answering with a negative string if the protocol version mismatch. This is to prevent the Arduino to keep asking
the host for connection repeatedly. Note: Support for negative answer string not yet added to Arduino side!
* Added all binary files to project in the .pro file into the 'other files' category.
* The cbm dirlist view now converts the underscore and circumflex characters to display the CBM font left and up
arrows. This makes it look more correct when entering (testing with) dos-wedge commands.
* The macro for declaration of dos command class in the header now makes it much more compact to declare a new command.
* Allowing unlimited amount of aliases (abbreviations) for a dos command.
* Further improved the parsing of leading characters in a command string (directory backslashes should EITHER move
up from an image or to the parent directory level
* Understanding the device number change command U0>n Changes on the fly if the close command comes.
Will need to detect this with the M-W command too.
* Protocol change to version #2 since close command now returns 'C' if last command was not LOAD/SAVE file.
* Fixed the detection of the version string (again), the problem was that the pendingBuffer was not cleared.
* Splitting string will keep empty when adding to dirlist window: This might cause some string to have some
unexpected extra line endings.
* Not sending FNF when save fails. Not sure if SAVE can detect errors???
* NOT clearing the queuedError when getting the close command. This would wrongly clear code before the error
channel has been read out.
* Settings dialog now accepts drive number 4-30.
2014-05-05:
* Fixed protocol version parsing in connection string, first try was buggy and didn't match properly.
* Fixed date/time generation on host side and parsing on ardino side, both were buggy.
* Removed some compilation errors caused by conditionals when compiling release.
2014-04-30:
* Added setting for specifying the border size (frame) in the CBM simulated list view. It is added in the
settings dialog and is an integer between 0 and 100. Useful if you don't want that frame to take up screen
estate. Nostalgic feeling however recommends a setting of 60 here (ehm, or even 64).
* Added a utility.hpp header for placing very general helper functions, definitions (macros) or class(es).
* Automounting of disk image when creating a new image through the new command is removed. It doesn't really work
in a nice way to propagate the mounting events when it comes indirectly like this.
* Added disk write protect handling for dos commands new, scratch, rename.
* Fixed/improved directory path parsing at beginning of path like slashes, colons, root specification etc.
* Finalized M2I handling, newdisk, delete, rename, open for writing new/existing.
* Simulation mode of saving file.
2014-04-23:
* Readded the srqIn pin number to be transferred in answer upon connection and made it persistent in settings again.
* Modified connection answer string so that it contains date and time, arduino scans the string and stores the date
and time when receiving it.
* Host side check whether the protocol version matches when connect request is received. Refuse connection if mismatch
and issues error in application log. Current (first) protocol version is 1. The connection request string is now
changed to 'connect_arduino:<version>\r'
* Only capital letters in protocol control characters are allowed. This is to differentiate the connection request
string from other control characters. This meant that the 'r'<size> sequence was changed to 'N'<size>.
* The connection request string can now be issued and is checked for even if it host side thinks it is connected.
This will enable reconnection even if the arduino suddenly crashes or resets for unknown reason while connected and
then tries to reconnect.
* The arduino interface class now handles date and time, it is prepared for serving date and time if requested by the CBM.
The IEC protocol part of this is not finished yet.
2014-04-03:
* Refined user interface to that minimum of control are shown leaving much more space for image list,
and directory list. Much more efficient in space. New dialog for mounting specific file at given location.
Added to settings dialog the image directory path instead of main dialog.
* Added new icons for menus and some other buttons that was missing icons.
2014-03-25:
* In both the arduino and Qt application the open command 'O' has changed
the format so that it is counted with a length specifier instead of CR or zero termination.
Reason is that commands may contain any byte, for instance if is writing data to 1541 memory or raw.
* In FileDriverBase added virtual method supportsType where a file system can be inquired whether
it supports the given file by checking its extension.
The method default implementation uses the extension() method to enumerate all file extension
and find out whether it is available.
* Added virtual newDisk (format) method in filedriverbase. Only M2I format supports this as of now.
This should be added support for T64, D64, G64 further on. Only skeleton in D64 exists,
unsure how to call it as an instance method though.
* Renamed openHostFile and closeHostFile to mountHostImage and unmountHostImage as more suitful names.
* dos copy command implemented parsing for, but only implemented for nativefs.
* Memory Write command implemented to some extent, but must be tested still!
* All dos commands are now parsed as byte arrays and not as qstrings because they must be terminated
with a container that uses length specifier and not zero terminations.
* Made some code refactoring and tidying in the interface class on the Qt side.
* File writing/creation in M2I-container added. But this is still needed to be tested, probably not working yet.
* Added simulation of dos commands (in 'wedge' style) entered in the cbm-view. This is only added for debug
builds and is used to test implementations without having to rig the complete system with hardware and all.
Testing is added with parsing of command and results by using a simulated state-machine controlled with an enum
that gets new additions for each new thing to test.
* BUGFIX: The resetPin assignment was not made persistent with QSettings, only read out with default value.
* NEW: CBM-view now simulates a more true to the nature scrolling cbm screen where text at top and bottom disappears
instead of being remembered like in a typical qtextedit control.
MMC2IEC Change Log
================================================================================
June 9, 2007: Version 0.8 : By Larsp. This version is on mmc2iec batch 1 units
- Huge change to interface.c and d64driver.c and t64driver.c. A function pointer
interface is now utilized for the different file formats, cleaning up the code
and allowing elegant implementation of multiple file formats.
- Save-With-Replace implemented.
- M2I file format introduced allowing 16 char petscii filenames with read/write
access. The file is a simple index with the petscii filenames and
corresponding FAT files.
- Command channel commands implemented. Scratch and Rename works in FAT mode and
in M2I mode they also work with wildcards. New disk also works and initializes
a new M2I file with the given name.
- Error channel messages implemented.
- Device 10/8 selection jumper implemented. In conjunction with device 9/8
jumper, device 8, 9, 10, 11 is now selectable.
- IEC_driver.c now actually uses config.h settings.
================================================================================
May 13, 2007: Version 0.7 : By Larsp
- config.h introduced. Hardware configuration and other flags are defined in
this file. It is also possible to disable v0.7 hardware features, to make
hardware requirements equivalent to v0.6.
- IEC protocol has been fixed to allow multiple IEC devices on the bus.
- Mechanical card detect switch is taken advantage of now. When no card is
present, ?FILE NOT FOUND occurs. When a card is present, it is repeatedly
initialized (BUSY LED flashes) until successful. This feature practically
eliminates the need to use load"<<",8 to initialize the card.
- Mechanical write protect switch implemented. The sdcard module will fail to
write sectors if write protect.
- Minor space savings and improvements in FAT driver. If FAT driver fails to
write changes back (e.g. write protect), DIRTY LED will simply keep being lit.
- Device 9/8 selection jumper implemented.
================================================================================
April 24, 2007: Version 0.6.1 : By Spaceman Spiff
- Zapped the hex2char function from util.c. This function is not used, and was
not correct.
- Fixed a lot of string types to signed char instead of unsigned char, since this
is the default for the C library functions. This gets rid of the "passing arg xx
to function yyyyy differ in signedness" which otherwise happens with newer
compilers.
================================================================================
April 5, 2007: Version 0.6
- IEC_driver.c
The IEC protocol timing values are now set using #defines and the timing has
been corrected to achieve better stability.
Communication works with C64 as well as DTV now.
- t64driver.c
Support for T64 files that has the "num used" value wrong which is apparently
very common.
- interface.c
Bug fix: Before, the interface was not properly initialized at cold reset, and
this was not apparent to the user. Now that situation IS apparent, and the
interface IS properly initialized.
Improved error handling and messaging.
Support for P00 files.
- sdcard.c
Detection of failed SD/MMC communication
================================================================================
February 5, 2007: Version 0.5
- First release
