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.
On some systems it can happen that the USB 'bus' number is a lot larger
than 64, but sr_usb_find() currently errors out if it is > 64.
Example:
Bus 250 Device 006: ID 1ab1:04ce 1ab1 DS1000Z Series[...]
Increase that limit so that the code will work everywhere. This bus number
is queried via libusb_get_bus_number() which returns an uint8_t, so we're
limiting to 255 here.
Thanks to 'ssi' on IRC for reporting the issue.
Apparently (some versions of) Mac OS X have the same problem with
usb_get_port_path() as FreeBSD does. Work around this in the same way.
Thanks to hanyazou@gmail.com for the patch!
This fixes bug #673.
The driver should now be able to cope with e.g. multiple ChronoVu LA8
and/or ChronoVu LA16 devices being connected to the same PC.
It now also provides the serial number and connection ID, which can be
used by frontends to differentiate multiple devices.
Also improve the scanopts / drvopts / devopts lists handling.
This fixes bug #504.
With the current driver API and the corresponding session event
handling, it is not possible to destroy and then re-create an
event source with the same key within the same main loop iteration.
The next generation driver API will fix this problem. But for now,
just change the driver to make do without that sort of thing. Also
increase the I/O timeout to 100 ms to be safer in the event of all
kind of delays the OS environment may induce.
This fixes bug #678.
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.
zip_discard() was introduced in libzip 0.11, which some systems
do not have yet. Provide a fallback replacement for zip_discard(),
and reduce the requirement to libzip 0.10 again.
This fixes bug #674.
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.
Added support for SR_CONF_REGULATION which returns value for CH1
Also VELLEMAN LABPS3005D (only device currently supported) sends single
'M' character in beginning of return value, which is specially discarded.
Trying to configure an invalid capture ratio would reset the
previously configured value. Instead, we should just reject the
new value and keep the original one.
