Soeren Apel d8fb599c67 lecroy-xstream: Wait for trigger before acquiring additional frames 2018-01-11 02:21:50 +01:00
Soeren Apel 724b4945d5 lecroy-xstream: Properly handle a stopping acquisition 2018-01-11 02:21:50 +01:00

Uwe Hermann d3f14af7ed hantek-dso: Capture ratio is a uint64_t. 
From src/hwdriver.c:

  {SR_CONF_CAPTURE_RATIO, SR_T_UINT64, "captureratio",
          "Pre-trigger capture ratio", NULL},
 2018-01-11 02:21:50 +01:00
Uwe Hermann 04069272b4 hantek-dso: config_set(): Shorten SR_CONF_CAPTURE_RATIO case. 
The sr_config_set() wrapper already checks for SR_CONF_CAPTURE_RATIO
being 0..100.
 2018-01-11 02:21:50 +01:00
Uwe Hermann be702d16d0 hantek-dso: Add missing SR_PRIV. 2018-01-11 02:21:50 +01:00
Uwe Hermann 6deb361bbf hantek-dso: Sample rate is a uint64_t. 
Also make 'base' uint64_t, otherwise there'll be compiler warnings.

Uwe Hermann ab8df2b1a6 hantek-dso: Random cosmetics, drop unneeded debug output. 2018-01-11 02:21:50 +01:00
Philipp Marek 8f484ca78e hantek-dso: dso2250: Fix capture runaway, only do the requested number of frames. 
After the first capture ->num_frames never got to be _equal_
to ->limit_frames; fixed by resetting to zero in dev_acquisition_stop(),
and protected against similar problems in the future by switching to
greater-or-equal instead.
 2018-01-11 02:21:50 +01:00
Philipp Marek 12f62ce620 hantek-dso: dso2250: Allow setting TRIGGER_LEVEL as well. 2018-01-11 02:21:50 +01:00
Philipp Marek 16a1dca4ad hantek-dso: Fix a memory leak. 2018-01-11 02:21:50 +01:00
Philipp Marek be10b96d40 hantek-dso: Fix segfault when accessing already free()d memory. 
This fix was guessed from other drivers' code.

This fixes bug #458.
 2018-01-11 02:21:30 +01:00
Philipp Marek 95983cc3fe hantek-dso: dso2250: It's not HORIZ_TRIGGERPOS but CAPTURE_RATIO. 
Seems a bit unfortunately named; if my current guess is right,
perhaps it should be
  :%s/SR_CONF_HORIZ_TRIGGERPOS/SR_CONF_HORIZ_DISPLAYOFFSET/g

Philipp Marek 11e3319656 hantek-dso: dso2250: Support sample rates correctly. 
Fast mode not done yet, only 125MHz allowed right now.
 2018-01-10 22:34:23 +01:00
Philipp Marek 3b2b703177 hantek-dso: dso2250: Report the sample rate back. 
So that cursor (and other) measurements and the time axis are correct.
 2018-01-10 22:34:20 +01:00
Philipp Marek 87f56d0178 hantek-dso: dso2250: Initial support for the Hantek DSO 2250. 
Crashes after first acquiration, but at least it _does_ acquire data.

Andreas Zschunke 5089a14345 hantek-4032l: Add initial driver implementation. 
[Note: This patch is basically a squashed version of the initial driver
commits by Andreas Zschunke <andreas.zschunke@gmx.net>, two fixes by
Andrej Valek <andy@skyrain.eu>, and various coding style / cosmetic
fixes by Uwe Hermann <uwe@hermann-uwe.de> to make the driver a lot more
consistent with the rest of the libsigrok code-base.]

Stefan Brüns bbcffe51d2 rigol-ds: Fix crash when fetching logic channels 
When refactoring the code, some places where sr_scpi_send was replaced
by rigol_ds_config_set the first argument was not changed from sdi->conn
to sdi. Fix the remaining ones.

Fix: https://sigrok.org/bug/1073

Uwe Hermann 8e45ba3f4e zeroplus-logic-cube: Fix Logian-16L metadata. 
According to a vendor software screenshot of a user on IRC, this
device is detected as having 200MHz max. samplerate and 128kBit
memory per channel.
 2017-12-25 15:42:06 +01:00
Uwe Hermann fb1d341d6e zeroplus: Add support for Meilhaus Logian-16L. 
Untested yet, but pretty likely to work.

Uwe Hermann 42d14d9108 sysclk-lwla: Fix a regression with (at least) the LWLA1034. 
This regression was introduced in f1ba6b4b2c.

Due to how the sysclk-lwla driver does up to 3 open/close operations in
one dev_open() API callback we cannot rely on the sr_dev_open() and
sr_dev_close() wrappers setting the sdi->status variable in this case.

Tested on LWLA1034.

Untested, so we don't know for sure it'll work.

This fixes bug #1045.

Frank Stettner 4f0463a079 drivers: Fix locale dependent string to float conversion 
Some drivers used locale dependent functions for converting strings
to float/double values. These functions fail when the decimal mark
is a "," in the locale settings but the string contains a ".".

This fixes bug #1064.

Soeren Apel 767ca13532 demo: Properly handle low samplerates 
A "low samplerate" in this case means anything where
samples_todo is less than SAMPLES_PER_FRAME. This case
wasn't handled properly before, resulting in wrong
amounts of data being sent out.

Soeren Apel e0b6855bd4 lecroy-xstream: Fix sample rate 
We can't use the memory size command because it returns
the *maximum* memory used, not the *actual* memory used.
Hence, we only know the number of samples per div once
sample data actually comes in.

Timo Rothenpieler 095eba19d6 hantek-6xxx: use lower MAX_PACKET_SIZE on Windows 
WinUSB seems to have a maximum size of 2M, reads of a larger size fail.

Soeren Apel e7d2cd1e05 lecroy-xstream: Use best-effort strategy for unknown models 
As there is a huge range of supported LeCroy scopes, naming
the IDN response for every single one of them is going to be
impossible. Hence, it makes more sense to treat all LeCroy
devices as if they were scopes and supported. This approach
lets users try to see how far they get and if they run into
issues, they can then be treated separately - e.g. by creating
a custom device profile.
Unless we do this, the vast majority of LeCroy scopes will
not be recognized by the driver.
