Add an "eevblog-121gw" subdriver entry for the EEVblog 121GW multimeter.
Use device dependent channel names instead of the default "P1" etc names.
It's assumed that the device's binary packet data is available at a COM
port. This means that an external BT to UART gateway is required until
BLE communication will be one of libsigrok's native connection types.
Due to some SCPI command changes that Siglent made, the connection
failed due to the wrong commands being send to the device.
This might fix parts of bug #1242, though initial tests show that
further changes might be needed.
[Note: This commit consists of multiple squashed commits from
marchelh <marchelh@gmail.com> and various fixups and rebasing
operations by Uwe Hermann <uwe@hermann-uwe.de>]
The previous implementation always dumped 23 data bytes for received
packets. This could result in truncated diagnostics information, and/or
access to invalid buffer content.
Rephrase the packet dump routine such that the specific meter's exact
packet length gets dumped, and use the common hex dump support code.

Default to the existing "P1" etc naming scheme for analog channels of
serial-dmm subdrivers. Add support for subdriver specific channel names
(which can reference the channel number if they desire). This is useful
for devices with multiple displays, or special purpose devices where
other names than P1 can better reflect the channel's nature.
Commit 556a926d43 introduced support for multiple displays in
subdrivers of serial-dmm, but also changed user visible channel numbers
to start from 0. Restore the previous behaviour, start counting from 1
which users may perceive as more natural (serial-dmm used to start at P1
in the past, scopes start with CH1 as well).
There are code paths where dev_close() tries to access a USB handle
which does not exist. This was observed with this command:
$ sigrok-cli -d brymen-bm86x --scan
On Windows, this device can either enumerate as 04b4:602a or 04b5:602a,
depending on which vendor driver is currently being used, so we have to
support both in the hantek-6xxx driver as well.
This fixes bug #1295.
The comment says "A requested value is certainly on the way", but the code no
longer works this way. The receive handler requests a value and blocks until
it is received. There is no value pending between receive handler calls, so
this code now only leads to a timeout.

This is happening because the send() and recv() functions
have different prototypes on POSIX and Windows. Using the casts
is required on Windows and doesn't hurt on POSIX systems.

The fx2lafw(4) driver supports mere logic analyzers as well as mixed
signal devices, but does not support channel group specific device
options. Avoid an error message when channel group device options get
queried, the condition is perfectly legal and non-fatal.
How to reproduce:
$ pulseview -d fx2lafw
$ sigrok-cli -d fx2lafw -g Logic --show
This fixes bug #1267.
The "firmware load failed" message would be even more helpful if users
could learn which firmware file failed to load. Add those filenames to
various FX2-based drivers.
This addresses bug #1262.
As per Daniel Anselmi <danselmi@gmx.ch> in an email conversation, the
code was actually written by Eva Kissling <eva.kissling@bluewin.ch>
(as indicated in the commit logs as well). Fix the headers accordingly.
Use "ipdbg-la" everywhere to refer to the driver, including
in function name prefixes etc. There's no need to encode
website details (.org) into the driver/function name(s).
