parameter.

984cdaeb03 Make nanoseconds_t a double to prevent overflow on very large numbers of 
revolutions (I've just seen a flux file with 50).

the disk.

9a5958f80b Prevent OOB when appending no bytes to a fluxmap. 2020-05-14 10:40:49 +02:00

2b53ac057c Fix some bugs which allow erasing tracks with F_FRAME_WRITE_CMD to work again. 
(F_FRAME_ERASE_CMD always worked.)

30646ccb07 Fix an Amiga decoder bug where truncated sectors would be considered valid (the 
Amiga checksum algorithm is weak and zero bytes don't contribute to the
checksum).

067af18103 When writing images, use the sector size in the spec rather than the actual 
data size, to avoid problems with multipart formats like the Amiga.

0367b7e77d Merge from trunk. 2020-04-01 00:06:35 +02:00

cd19fcdadd The CSV report now writes records for every sector in the output map, even the 
missing ones.

1954f02cfb Don't reset the device on startup because it confuses Linux. 2020-03-30 22:23:18 +01:00

39b23200b0 Fix missing flag dependency. 2020-03-29 23:12:12 +02:00

b1ea5a9a35 Rework the writer to use a fluxsink rather than just writing stuff directly. 2020-03-29 15:08:45 +02:00
David Given
1b48ea20c4 Remove the cruncher. 2020-03-20 00:06:07 +01:00
David Given
fc2655ecd6 Rework the bytecode format to use a much simplified setup: a six-bit timer with 
the top two bits reserved for pulse and index state. This is actually smaller,
bandwidth-wise, than the old version, and may be smaller than the crunched
version.
 2020-03-14 18:58:43 +00:00

37aa8b62b0 Add a --write-csv=X option to the reader to dump the sector status map as a 
machine-readable file.
 2020-03-14 14:35:19 +00:00

04c09d1a5b Hopefully, fix the problem where ^Cing a job gets the board in a confused 
state.
 2020-02-21 22:16:20 +01:00
David Given
323da8272a Hopefully add support for giving the reader a set of required sectors, so if 
one is missing then we can tell and the track can be reread.

1656947764 Disable write precompensation, as it actually seems to make things worse. 2020-02-18 22:49:12 +01:00
David Given
8acf8e181d Rework the crunch encoding to be, hopefully, smaller and use less bandwidth for 
HD disks.
 2020-02-18 21:37:32 +01:00

1a6c6b5420 The bandwidth tester now tests bandwidth in both directions. It looks like my 
default USB port only gets about 500kB/s write bandwidth. However, when plugged
into a port with 850kB/s, I still get underrun errors...

a63a90bbd0 Only attempt to remove the old file on overwrite if it actually exists. 2020-02-14 22:30:46 +01:00
David Given
d25f96dd24 The IBM encoder now works well enough that my USB floppy drive thinks the disk 
is formatted... but has trouble reading sectors above about 1000. Also remember
that encoding MFM needs to keep one bit of state at all times.

e8febe6508 Allow converting Bytes to bits, and slicing until the end of an object. 2020-02-14 00:04:31 +01:00
David Given
be41c1de76 You now need to explicitly specify whether flux files get merged or 
overwritten, because the old behaviour was weird. Reader uses SqliteFluxSink to
write flux files, rather than raw database accesses.

a8eca06cf0 Don't hang if we hit the end of stream while waiting for a data record. 2020-01-27 23:09:29 +01:00

29bdfc043a Allow fractional revolutions and non-synced reading. Find more things which 
need fixing in the firmware sampler.

91ffcf59c3 When reading data records, retry if we get an UNKNOWN record to work the 
occasional false positive (which happens now and again with MFM).

9dc1067032 Add --dump-sectors. Sector positions are recorded correctly. 2020-01-26 18:30:35 +01:00

6af80d1e5e Improve some messaging. A data record is always pushed, even if it's empty (to 
help debugging).

d77841c3b7 Add the ability to fake the index pulse source, allowing old drives to be used 
with FluxEngine.

7c66e1b0d4 Don't recalibrate after drive errors --- it's really annoying and I don't think it helps. 2019-12-14 21:43:48 +01:00
David Given
4475e9f085 Increase the default bit-error-threshold to 0.4, because that's the value I 
almost always end up using.

792cc88192 The Amiga writer now generates valid flux files --- but it looks like the 
writer's broken (both the Amiga and the Brother have failed).

32bb956710 Detect voltage levels *correctly*. 2019-12-11 00:05:34 +01:00

f436d6b582 Add a feature where we can measure the FDD bus signal voltages using the PSoC's 
ADCs. Increase the track step pulse width to 6us, because.

5a2b2bc07a Allow support for command lines with non-argument filenames. 2019-08-31 01:40:44 +02:00

7988d0fe24 Don't replace bad sectors with more bad sectors. This means that if a sector is 
permanently bad, the one which wins and goes into the output SectorSet is the
first one, not the last one. Frequently the last sector is truncated by the end
of read and so it isn't useful.
