Martin Ling 8f996b8948 probe_groups: API changes required to implement probe groups. 2013-11-08 01:03:16 +01:00
Uwe Hermann 1c2d542df2 demo: Use std_dev_clear(). 2013-06-02 16:57:07 +02:00
Uwe Hermann 3b412e3a30 s/clear_instances/dev_clear/.
Consistently use the same name for the dev_clear() API callback
everywhere.
2013-06-02 16:56:41 +02:00
Uwe Hermann f6beaac55c std: Drop hw_ from function names.
The per-driver API calls no longer have a hw_ prefix (e.g. hw_init()
became init() and so on), so drop the 'hw_' from the std versions
for those API callbacks too.
2013-06-02 16:46:18 +02:00
Uwe Hermann 6078d2c996 Use consistent API callback function names.
This now matches what the 'new-driver' tool generates.

Uwe Hermann decfe89d4e Drop some lines that are no longer needed. 2013-05-10 18:30:32 +02:00
Uwe Hermann 2a052cc4d6 Use consistent naming for internal libtool helper libs.
This now also matches what the 'new-driver' tool generates.
2013-05-10 17:44:01 +02:00
Uwe Hermann 9e165e742f Use consistent HW_ name prefixes everywhere.
Older drivers used LA_* previously, we now use HW_* everywhere though.

Uwe Hermann 29a27196a1 s/DRIVER_LOG_DOMAIN/LOG_PREFIX/.
This is more correct anyway, and also a bit shorter and more readable.

Uwe Hermann 3e9b7f9c77 Rename session_dev_id to cb_data everywhere.
We use 'cb_data' in all drivers these days, make the few remaining ones
that use 'session_dev_id' consistent.
2013-02-07 11:26:02 +01:00
Uwe Hermann 4afdfd4628 Add and use std_session_send_df_header().
This is a small helper function which sends the SR_DF_HEADER packet that
drivers usually emit in their hw_dev_acquisition_start() API callback.
It simplifies and shortens the hw_dev_acquisition_start() functions
quite a bit.

It also simplifies the input modules which send an SR_DF_HEADER packet, too.

This patch also automatically removes some unneeded malloc/free in some
drivers for the 'packet' and 'header' structs used for SR_DF_HEADER.

Uwe Hermann d3b38ad389 Drivers: Explicitly list sr_samplerates fields.
This makes it a bit easier to understand which value means what, just
from looking at the driver code.
2013-01-29 12:56:02 +01:00
Uwe Hermann 063e7aef6d Factor out common hw_init() driver code.
Most drivers do pretty much the same things in their hw_init()
right now, so factor out that code to std_hw_init() in std.c.

Uwe Hermann 4b97c74e0b sr_driver_scan(): Improve checks.
Check the relevant arguments for != NULL before calling the actual
driver-specific function, so that the driver can safely assume those
arguments are non-NULL. This removes the need to duplicate these
checks in every driver.

Also, do some minor whitespace and consistency improvements.

Uwe Hermann c0eea11c45 sr_driver_init(): Improve checks.
Check the relevant arguments for != NULL before calling the actual
driver-specific function, so that the driver can safely assume those
arguments are non-NULL. This removes the need to duplicate these
checks in every driver.

Also, change one SR_ERR to the more correct SR_ERR_MALLOC, and assign
sr_ctx in the rigol-ds1xx2's hw_init() function, like all the other
drivers do.

Bert Vermeulen 1987b8d63e drivers: use new sr_config struct
Sending an SR_DF_META packet at the start of every stream is not
mandatory; the frontend should ask for what it needs, and any extra
information the driver wants to send will come in due time.

Bert Vermeulen 6b8d6f93bb Get rid of obsolete SR_DI_NUM_PROBES and SR_DI_PROBE_NAMES.
Frontends should use the probe list in the device's sr_dev_inst
to get this information.

Uwe Hermann 35e199da50 Fix limit_samples check in various drivers.
Check whether a sample limit was actually set (> 0) before checking if
that sample limit is reached. This also fixes continuous acquisition mode
for drivers which have that.

Use 'di' consistently in all drivers as the name for a local, static
pointer to the respective driver's 'struct sr_dev_driver'.

Alexandru Gagniuc 3b20367381 demo: Do not use a separate thread for generating data
We already have an event-based mechanism in place. Using a thread just
adds unneeded complexity, especially for a driver designed not for
performance, but for providing a testbed to frontends.
Generate the data in the event handler, not in a separate thread.

Alexandru Gagniuc c216d62307 demo: Properly stop acquisition after reaching our sample quota
The demo driver was using sr_session_source_add_channel() to add
a poll source, but was relying on sr_session_run_poll() to call
sr_session_source_remove(). This, coupled with the design of the
driver caused errors once the samples were collected.

The error stream was most likely related to failing to properly close
one of the channels.

Alexandru Gagniuc 49145a63c7 demo: Be more verbose about starting/stopping acquisition

being called and what is not _and_ have it show up in the logs.

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.
