So far, it seems we can make this work with just hw_init() needing to
be subdriver-specific (it will point 'di' to the respective per-subdriver
entry), the rest of the API functions can then use a strcmp() on di->name to
learn which subdriver they belong to.
The 'uni-t-dmm' driver/directory will not appear as a "driver" to
frontends anymore, it's just an internal thing.
The frontends will see a uni-t-ut61d and voltcraft-vc820 driver now,
with the correct names and parsers etc. attached to them.
This is not fully finished yet, but it's a start (and works mostly):
$ sigrok-cli -D
The following devices were found:
UNI-T UT61D with 1 probe: P1
Voltcraft VC-820 with 1 probe: P1
$ sigrok-cli --driver voltcraft-vc820 -D
The following devices were found:
Voltcraft VC-820 with 1 probe: P1
$ sigrok-cli --driver uni-t-ut61d -D
The following devices were found:
UNI-T UT61D with 1 probe: P1
# Now attaching a UNI-T UT61D device via USB.
$ sigrok-cli --driver uni-t-ut61d --samples 3 -O analog
P1: -0.017800 V DC
P1: -0.017600 V DC
P1: -0.017700 V DC
# Now attaching a Voltcraft VC-820 device via USB instead.
$ sigrok-cli --driver voltcraft-vc820 --samples 3 -O analog
P1: -0.319200 V DC
P1: -0.319300 V DC
P1: -0.319300 V DC
The Fortune Semiconductor FS9721_LP3 and FS9721B/Q100 DMM chips are very
similar and the protocol looks identical.
Tested on a Voltcraft VC-820 (FS9721_LP3) with the uni-t-dmm driver
(needs some small changes, tbd).
Turn TODOs which should be user-visible into @todo so that Doxygen
shows them in the function docs, and also on the special "Todo List" page.
Those TODOs that should not be in the Doxygen docs are moved out of the
/** */ comment blocks.
Also fix some comments/items, and remove some obsolete ones.
- Turn SR_OK/SR_ERR_* and SR_LOG_* into proper enums.
- Use /**< Foo. */ for Doxygen comments that are on the same line as
the (e.g.) enum entry they document. If the comment is not on the
same line (but rather directly above the enum entry) a simple
/** Foo. */ comment is sufficient.
- Use /** */ instead of /* */ in some places, so that Doxygen actually uses
the respective comments.
- Various smaller cosmetic fixes or cleanups.
- Show a short project description, the libsigrok version (x.y.z or
"unreleased development snapshot"), and the sigrok logo in the
Doxygen output.
- Ignore a bunch of files and directories which don't contain public
libsigrok API anyway.
- Remove the SR_API prefix from the Doxygen output (all
functions/symbols in the output are part of the public API anyway).
- Various changes of settings to get nicer and more useful output.
LOGIC mode sends the following data:
V < 0 : actual voltage
0 <= V < 1 : LOW
1 <= V < 2 : actual voltage
2 <= V : HIGH
We follow the same idea, and set our unit to BOOLEAN for the crazy
case (HIGH or LOW).
