Bert Vermeulen 69b07d14db allow for intermediate stage in stopping acquisition
In the case of USB drivers, a driver's dev_acquisition_stop() cannot
simply remove its fd sources from the session and close its devices:
a USB transfer might still be underway, and it needs to be finished
(and its memory freed) properly.

An sr_dev_inst->status value is added: SR_ST_STOPPING, which should
be set when the driver's dev_acquisition_stop() is called, and acts
as a marker for the USB event handler to wind up its operations.

In order for dev_acquisition_stop() to be able to set the sdi status,
however, it needs to be unconstified.

Add some TODOs.

Uwe Hermann 545f978639 config.h usage cleanups.
- Drop config.h #include from files that don't actually use any of
   its contents (at the moment).

 - Add comment for those that do need it.

Bert Vermeulen 19b0cce312 hantek-dso: use default libusb context 2012-09-11 21:16:16 +02:00
Bert Vermeulen 811deee4af sr/drivers: add API calls sr_dev_inst_list() and sr_dev_inst_clear()
These are used to list the device instances currently known to the driver,
and clear that list.

Drivers that don't necessarily clear their list of instances on every scan,
such as genericdmm, need to provide these to the frontend to keep instance
management sane.

Bert Vermeulen 014359e329 sr/drivers: obsolete SR_HWCAP_PROBECONFIG
Since probes now live in a struct sr_dev_inst owned by the driver, it
already knows about them. Instead of a frontend telling the driver to
configure probes, all driver now do this just before starting acquisition.

Bert Vermeulen 9e90dcba9c sr/drivers: remove driver API call dev_status_get()
It's obsolete: no frontend ever used it, and neither did libsigrok.
The sdi->status field is only used internally by some drivers, and
should probably be moved to the driver-specific context structs.

Bert Vermeulen 6f4b1868e8 sr/drivers: use sr_dev_inst instead of device index for dev_config_set()
All driver API calls using device index as a parameter will instead use a
const struct sr_dev_inst.

Bert Vermeulen 61136ea603 sr: add new driver API call: scan()
This changes the semantics of the init() call as well. That now only
initializes the driver -- an administrative affair, no hardware gets
touched during this call. It returns a standard SR_OK or SR_ERR* code.

The scan() call does a discovery run for devices it knows, and returns
the number found. It can be called at any time.

Bert Vermeulen 40dda2c3a5 sr: remove unused argument from hardware driver function init()
It was actually used in one way: the session file loaded abused it for
passing in the filename -- something it definitely wasn't intended for.
This now uses the proper way to pass arguments to a driver: the new
SR_HWCAP_SESSIONFILE.

The OLS driver could also use it as an indication of the serial port to
use instead of actively probing all serial ports on the system, but there
wasn't any frontend code that passed in such a parameter, making it
entirely useless. That will soon be handled differently with the new
scan() API call, regardless.

Bert Vermeulen 45c59c8bdd sr: moved sigrok.h so libsigrok/libsigrok.h
All frontends will have to include <libsigrok/libsigrok.h> from now on.
This header includes proto.h and version.h, both installed from the
distribution into $INCLUDE/libsigrok/ as well.

The only dynamically changed header is now version.h, which has both
libsigrok and libtool compile-time versions in it.

Bert Vermeulen e749a8cb50 hantek-dso: start sending the frame only from the trigger point
Samples received before the trigger point are stored. From the
trigger point on, every chunk received from the device is sent
up the session bus. After the device has finished sending, the
stored samples are transmitted.

Uwe Hermann 9956f2851f sr: analog: Add MQ and UNIT enums.
MQ is the measured quantity, e.g. voltage, current, temperature.

UNIT is the unit in which these quantities are measured, e.g. volt,
ampere, celsius, kelvin, etc. etc.

The same MQ can be specified in different UNITs by the driver, depending
on what the hardware reports. Conversion is left to the frontends.

Bert Vermeulen 6e6eeff47a hantek-dso: capturestate packet also contains the trigger point
Not yet used, but it's the key to knowing where in the frame to
start displaying; the frame is used as a circular buffer, and what
is sent is effectively a snapshot.

Uwe Hermann 384c28d9e7 sr: hantek-dso: Use portable g_ntohs() function.
The ntohs() from <arpa/inet.h> is not available on MinGW/Windows. There
are ways to work around this, but as we use glib already, using g_ntohs()
is the best option anyway.
