Here's a patch to "Ignore requests to set coupling for the Hantek 6022BE",
this clears the LIBUSB errors for me.
Also in the patch:
- There is a crash because config_list() can be called with sdi == NULL.
This can be reproduced by doing:
"sigrok-cli.exe --driver hantek-6xxx --show"
- There seems to be a very unsafe loop in config_set() when setting COUPLING;
the coupling vector is assumed to be zero terminated, but is not declared
as such.
Note: The same issue is present also for other hardware, at least for
hantek-dso/api.c. The patch is only for hantek-6xxx though.
There were issues when using non-power-of-two data sizes with e.g.
the Hantek 6022BE device. For example, on Windows the acquisition would
simply hang and never complete:
hantek-6xxx: receive_transfer(): status LIBUSB_TRANSFER_ERROR received 0 bytes
The issue was reported by Erik Montnemery on the mailing list, the
original patch was posted by "mmark" here (thanks!):
http://www.eevblog.com/forum/testgear/sainsmart-dds120-usb-oscilloscope-(buudai-bm102)/msg911729/#msg911729
The issue has been verified by me on Windows and Linux, and also that
this change does indeed fix it (tested Hantek 6022BE and Sainsmart DDS120).
Neither PulseView nor sigrok-cli hang anymore on Windows, and on Linux
the log messages suggest improvements as well:
-hantek-6xxx: data_amount 712
+hantek-6xxx: data_amount: 200 (rounded to power of 2: 512)
-hantek-6xxx: receive_transfer(): calculated samplerate == 2327ks/s
-hantek-6xxx: receive_transfer(): status LIBUSB_TRANSFER_OVERFLOW received 512 bytes.
+hantek-6xxx: receive_transfer(): calculated samplerate == 1969ks/s
+hantek-6xxx: receive_transfer(): status LIBUSB_SUCCESS / LIBUSB_TRANSFER_COMPLETED received 512 bytes.
This fixes bug #821.
Some functions in std.c were using
const char *prefix = sdi->driver->name;
but were called from input/output modules as well (which don't have
a "driver" field).
As a temporary workaround, use "unknown" as prefix in such cases until
a more permanent solution is implemented.
This fixes bug #813.
This fixes the following build issue on OSX:
Undefined symbols for architecture x86_64:
"_sr_drivers_init", referenced from:
_sr_init in backend.o
This closes bug #802.
When a meter display 105.2 kΩ, libsigrok will return 105200 Ω
but it is really valuable to know that the last 2 digits are not
significant, so encoding.digits should be set to -2.
This would allow a sigrok client to display 105200 as 105.2 k
instead of 105.200 k.

This patch restores the previous unterminated SCPI message logging:

As it's located in the general logging mechanism, we deal with any
additional (and unwanted) newlines this way.
This single object also contains the sr_drivers_init function, that will
always be referenced. That ensures that the drivers object files won't
be optimized out during static linking due to the fact that they are
not referenced directly.
This addresses (parts of) bug #802.
These functions were only used in the SR_DF_ANALOG_OLD case,
whereas the SR_DF_ANALOG case already used functions and lists
from src/analog.c.
This closes bug #636.
When config_list() gets NULL as sdi, it must return driver opts.
Some drivers, including zeroplus, don't check sdi and return both
driver opts and device opts.
Now that std_serial_dev_acquisition_stop() has the same signature as
the sr_dev_driver dev_acquisition_stop() callback it is possible to remove
the wrapper functions and use std_serial_dev_acquisition_stop() directly

All callers of std_serial_dev_acquisition_stop() currently pass the same
callback for the dev_close_fn parameter as the dev_close callback of their
sr_dev_driver struct. Remove the dev_close_fn parameter and invoke the
drivers dev_close() callback directly. This simplifies the API and ensures
consistent behaviour between different drivers.

All callers of std_serial_dev_acquisition_stop() currently pass sdi->conn
for the serial parameter. And the other std_serial helper functions already
require that the conn field of the sr_driver_inst passed to the functions
points to the sr_serial_dev_inst associated with the device.
Modify std_serial_dev_acquisition_stop() to follow the same pattern and
remove the serial parameter. This simplifies the API and ensures consistent
behaviour between different drivers.

Some of the standard helper functions take a log prefix parameter that is
used when printing messages. This log prefix is almost always identical to
the name field in the driver's sr_dev_driver struct. The only exception are
drivers which register multiple sr_dev_driver structs.
Instead of passing the log prefix as a parameter simply use the driver's
name. This simplifies the API, gives consistent behaviour between different
drivers and also makes it easier to identify where the message originates
when a driver registers sr_dev_driver structs.

All drivers with the exception of pce-322a pass their dev_close callback to
std_serial_dev_acquisition_stop(). The pce-322a passes std_serial_dev_close()
which is also called from its dev_close() callback and replicates the other
functionality of its dev_close() callback directly in
std_serial_dev_acquisition_stop().
Refactor this to pass the dev_close callback function directly to
std_serial_dev_acquisition_stop(). This makes sure that the driver is
consistent with other drivers and also removes duplicated code.

The version field in the norma-dmm driver state struct is initialized, but
never read and the same information is also already available in the
sr_dev_inst struct version field. So remove it to simplify the code.
This allows to get rid of the custom dev_close() callback and just use the
standard std_serial_dev_close() instead.

Some driver scan() functions only ever return a single device. For those it
is possible to slightly simplify the handling of the device list by
creating it on demand when the function returns.
Some drivers also have the following expression:
devices = g_slist_append(devices, sdi);
...
if (!devices)
...
This check will never evaluate to false so it is dropped as well.

A common task during device scan is to add the newly discovered devices to
the instance list of the driver. Currently this is done by each driver on
its own. This patch introduces a new helper function std_scan_complete()
which takes care of this. The function should be called at the end of a
driver's scan() callback before returning the device list.
Doing this with a helper function provides guaranteed consistent behaviour
among drivers and hopefully paves the way to moving more standard
functionality directly into the sigrok core.
Another common task that every driver has to do for each device instance is
to initialize the device's driver field. So this is done in the new helper
function as well.
All drivers that can make use of the new helper are updated.

Some drivers set the device instance list to NULL in their scan() callback.
This means the driver loses all references to any devices contained in that
list and their resources will be leaked. Drivers can't free the devices at
this point either since an application might still use a device on the
list. So the existing devices on the instance list need to remain
unmodified during the scan() callback, even if that means that there will
be duplicates on the instance list. Only an explicit invocation of
sr_dev_clear() by the application is allowed to free the devices on the
instance list and reset the list.

The link-mso19 driver currently iterates the device instance list of the
driver to get the device instance for which the callback is called.
But the device instance is actually passed to the callback as the cb_data
parameter, so just use that instead and remove the lookup loop.
Besides that the current lookup loop does not even compile either.
Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
The link-mso19 open-codes the std_dev_clear() function and uses it as its
custom dev_clear() callback. The std_dev_clear() function is automatically
called if no custom dev_clear() callback is specified, so just drop custom
implementation and use the default.
This also fixes a memory leak where the link-mso19 driver did not properly
free its driver state struct in the dev_clear() callback.

HP instruments predating the 488.2 and SCPI standards do not
necessarily have a SCPI-compliant command set. The HP6630A series of
supplies is one such example.
While scpi-pps is flexible enough to accomodate almost any command
syntax given the right profile, it still assumes that "*IDN?" is the
correct question to ask the instrument. Since older HP gear instead
responds to "ID?", this assumption is no longer true.
Thus sr_scpi_get_hw_id() is not appropriate for these instruments, and
the shadow driver added here only replaces that function call, while
reusing the rest of the existing logic. The extra noise is necessary
in order to propagate this through the .scan member of the driver.
Use the standard connection_id field from the struct sr_dev_inst for
storing the device address rather than using the custom address field in
the driver state struct. This makes things more consistent with the
framework.

The sigrok core needs a list of all available drivers. Currently this list
is manually maintained by updating a global list whenever a driver is added
or removed.
Introduce a new special section that contains the list of all drivers. The
SR_REGISTER_DEV_DRIVER() and SR_REGISTER_DEV_DRIVER_LIST() macro is used to
add drivers to this new list. This is done by placing the pointers to the
driver into a special section. Since nothing else is in this section it is
known that it is simply a list of driver pointers and the core can iterate
over it as if it was an array.
The advantage of this approach is that the code necessary to add a driver
to the list is completely contained to the driver source and it is no
longer necessary to maintain a global list. If a driver is built it will
automatically appear in the list, if it is not built in won't. This means
that the list is always correct, whereas the previous approach used ifdefs
in the global driver list file which could get out-of-sync with the actual
condition when the driver was built.
Any sr_dev_driver structs that are no longer used outside the driver module
are marked as static.

Most drivers have a forward declaration to their sr_dev_driver struct at
the beginning of the driver file. This is due to historic reasons and often
no longer required. So remove all the unnecessary forward declarations.
Some drivers still require the forward declaration, but only reference the
driver struct from within the driver scan() callback. Since the driver
struct is passed to the scan callback replace the references to the global
variable with the local parameter. In some cases this requires adding the
parameter to some of the helper functions that are called from the scan()
callback.

Binary block data is specified in IEEE 488.2. First character is '#',
followed by a single ascii digit denoting the the number of digits needed
for the length specification. Length is given in bytes.
This allows drivers to replace retrieval of comma separated ASCII values
with binary formats. See bug #791.
