-
Nikolay Nikolov committed [r503] on Code
* updated PCB, fixed some DRC errors
-
* some DRC fixes and cleanup
-
* moved the floppy logo slightly upwards
-
* update PCB to rev.2; added D1 diode
-
* update footprints
-
+ placed R1 on the PCB
-
* updated the polarized capacitor symbol to use the new KiCad 6 library
-
* update project to KiCad 6
-
* updated files
-
* updated PCB to rev. 2: added diode D1
-
* updated poliarized capacitor symbols to use the new KiCad 6 library
-
* upgrade to KiCad 6
-
* updated copyright year
-
+ use the faster, more efficient and more reliable timer based reading of data
-
* pullup all unused pins on the ArduinoMegaDisk2 controller
-
* always use the XMemBuf for reading tracks, if available, for better stability
-
- removed unused and incorrect constants
-
* fixed firmware bug when writing from the internal buffer
-
+ added format check for the amiga decoder
-
+ workaround for FPC 3.2.0 bug
-
* updated copyright year
-
* increased Gap1 to 600 for the Amiga (overkill, but using a large value for Gap1 should be safe)
-
- removed the MFM sector size table from unit mfmamiga, because that is not used on the Amiga
-
- removed unused unit Util
-
- removed commented out code from unit mfmamiga
-
- removed GetMFMSectorSize from MFMAmiga
-
* Gap0 and Gap4 for the MFM_AMIGA writer renamed Gap1 and Gap2
-
+ add a small gap after the track
-
+ initial (untested) implementation of Amiga floppy format write support
-
+ support reading .adf files in the MFM_AMIGA disk writer
-
- get rid of FCurrentSectorSize
-
- removed unused local var
-
+ also check the Amiga sector header checksum
-
+ implemented Amiga sector data checksum checking
-
- cleaned up unused MFM code from the Amiga MFM decoder
-
+ Amiga .adf format support added
-
* DecodeAmigaHeader renamed DecodeAmigaSector
-
* moved the try..except outside DecodeAmigaHeader
-
- removed redundant for loop
-
* fixed whole track decoding
-
* alternative method for reading more sectors
-
* first attempt at calculating the header checksum, not working, unfortunately
-
* converted the sector label buf to longwords
-
+ decode the sector label correctly
-
- removed TestWrite local procedure, because it's no longer used
-
+ Amiga sector decoding implemented
-
+ test decoding of a sector, not sure if correct
-
+ read the header and data checksums
-
+ decode the sector label
-
+ decode amiga mark and header
-
+ added unit mfmamiga, for now it's a clone of the mfm unit
-
Arduino Mega to PC Floppy Interface rev.1
-
+ run a quick XMem memory test on startup and disable the XMem bus if the test fails
-
+ added a bank select XMEM memory test as well
-
+ added a XMem memory test diagnostic function
-
- removed FormatTrack_GCR, since it's not used
-
+ introduce object TPortInputLine in the add/edit controllers dialog
-
* raise an EDiskDriveControllerError in case of an input/output error during opening of the serial device
-
+ introduce and use the EDiskDriveControllerError exception class
-
Windows support
-
* Windows fixes
-
* use a single file handle for serial input and output communication
-
* switch to using untyped files instead of text files for the serial device communication
-
+ serial output also piped through the newly introduced Serial_WriteChar, Serial_WriteInteger and Serial_WriteString methods
-
+ introduced Serial_ReadChar; all serial port reading goes through it now
-
* updated by Lazarus 2.0.2
-
Verification of the recording after writing
-
Automatically setting the sector gaps when writing
-
Manually setting the sector gaps when writing
-
Setting the interleave factor when writing images

Write precompensation support
-
Linux serial port initialization doesn't work the first time
-
Linux serial port initialization doesn't work the first time
-
* fix for bug #6 - the Arduino serial interface wasn't working immediately after
-
+ also print the available verbosity levels when an invalid verbosity level has been specified
-
+ print the available verbosity levels if the -v option is used without a parameter
-
* improvements to the write command error messages
-
* updated copyright year

Write precompensation support
-
Writing to PC floppy
-
This works now. The only thing missing is write precompensation support.
-
+ force the user to specify the read track mode to the read command
-
+ added rtm_Unspecified and wtm_Unspecified read/write track mode values
-
* force the user to specify the cylinder and head count when using the read command
-
* some improvements to the read command error messages
-
* moved the print functions up
-
+ better error handling for unknown parameters for the decode command
-
* slight improvement to the error message
-
+ more helpful error messages for the decode command
-
* sort the commands in alphabetical order in the main case statement
-
* huge improvements to the command line help command output
-
+ the usage page moved to a new 'help' command
-
+ added debug and release build modes
-
* allow accessing up to 84 tracks
