Do not use size_t for values whose width is defined by the device,
not the host. Also don't use size_t for simple indices with known
small range, unless type compatibility considerations apply.
Refactor the sysclk-lwla driver to separate the generic logic from
the model-specific implementation. Based on this, implement support
for the SysClk LWLA1016 device.
Evaluate all 64 bit of the duration field in the capture status
record. Although unlikely in practical use, due to compression
it is possible for the duration in ms to exceed 32 bit.
During initialization of the LWLA1034, read the 64-bit test word
twice and verify the result of the second read only. This better
matches what the original vendor software does.
Apparently, these four registers form an interface for indirect
access to another internal 64 bit wide memory. This is likely the
same memory as that accessed by the bulk transfer commands 7 and 8.
After opening the USB device, set the device configuration to 1.
Actually, do it twice, just as the vendor driver seems to do. This
is supposed to trigger a lightweight reset of the device.
Originally, I omitted this reset sequence from the sigrok driver
because it simply did not work at all for me. However, it does seem
to work now, so that may have been a problem in libusb or the kernel
which is now fixed.
With some luck, this change may finally fix#327.
Use states SR_ST_ACTIVE and SR_ST_INACTIVE to indicate that the
device is open or closed, respectively. Do not use any of the
other state values. Improve the robustness of the open and close
methods in face of errors. Introduce a separate flag to indicate
that a running acquisition should be canceled.
Prepare the trigger masks at config_commit() time, so that the
trigger setup can be validated before starting an acquisition.
Accordingly, do actually report validation errors back to the
caller.
It turns out that g_stat() breaks apart when using 64 bit stat on
32-bit systems. Since the actual type of GStatBuf is decided when
glib/gstdio.h is included, it is thus possible for GLib itself to
be compiled with a different type than user code.
Ouch. Unfortunately going back to plain stat() also means that we
lose Unicode filename support on Windows.
Since Autoconf places some important feature flags only into the
configuration header, it is necessary to include it globally to
guarantee a consistent build.
Move the include flags for files in the source tree from
configure.ac to Makefile.am where they belong. Also use
AM_CPPFLAGS instead of CFLAGS/CXXFLAGS to make sure the
files in the build/source tree are always picked up first.
Also, remove the include/libsigrok sub-directory from the
search path, thereby making the <libsigrok/> prefix mandatory
when building libsigrok itself. This matches the convention
already imposed on users of the library.
This was originally done as an optimization in combination with a list
reversal which has since been removed from the code. Thus, un-reverse
the channels so that the UI lists them in the correct order again.
Add LIBUSB_CALL where needed to avoid warnings such as the following:

(lwla_convert_trigger): Fix trigger mask computation bug introduced
by recent change: Widen constant to 64 bit before shifting so that
channel nunmbers beyond 32 are processed correctly.
Every driver now publishes its device option config keys, i.e. the
list fetched with sr_config_list(SR_CONF_DEVICE_OPTIONS), with a
set of flags indicating which methods are implemented by the driver
for that key.
The config keys are OR'ed with any combination of SR_CONF_GET,
SR_CONF_SET and SR_CONF_LIST. These are defined as the high bits
of the uint32_t config key. Clients can OR config keys with
SR_CONF_MASK to strip out these bits. This mask will be kept up to
date if other bits are added to the capabilities list; clients MUST
therefore use SR_CONF_MASK for this.
Some keys don't have capability bits added, such as the informative
device type keys (SR_CONF_MULTIMETER, SR_CONF_OSCILLOSCOPE, ...) and
SR_CONF_CONTINUOUS.
Scan options do not have capabilities bits.
