Uwe Hermann 17548571cc zeroplus: Only report supported samplerates.
The currently supported model LAP-C(16032) doesn't support the
samplerates 150MHz and 200MHz which some of the other models have.

Thus, do not report these samplerates to the frontends. E.g. sigrok-cli
should not show them via --show and GUIs should not list them in their
"Samplerates" drop-down.

Uwe Hermann 58c5f2ed17 zeroplus: Split into api.c and protocol.c. 2013-02-08 21:53:50 +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 961009b0c4 hw_dev_close(): Move common checks to wrapper.
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.

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.

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 035a1078fd drivers: rename and reorganize config get/set
The driver API calls info_get() and dev_config_set() have been renamed
to config_get() and config_set(), respectively.

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.
2013-01-21 23:32:49 +01:00
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.
2013-01-15 17:42:23 +01:00
Uwe Hermann 7869340103 Shorten probe_names[] arrays everywhere.
Also, NULL-terminate all of them.

Uwe Hermann a873c5940c Consistently use 'di' as variable name.
Use 'di' consistently in all drivers as the name for a local, static
pointer to the respective driver's 'struct sr_dev_driver'.

Uwe Hermann 64d33dc28e All drivers: Drop unneeded comments. 2012-11-11 18:09:11 +01:00
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.

Toshiaki Yoshida 0ab0cb942f zeroplus-logic-cube: Fix samplerate and trigger
- Default to 1MHz.
   The default sample rate is the lowest frequency (100Hz),
   but it takes a very long time until 128K memory is full.

 - Fix the 1MHz setting.

 - Use samplerate list.

 - Fix 10MHz frequency.

 - Fix trigger.

 - Change the size of memory according to the number of samples.

 - Add pre-trigger (capture ratio) setting.

 - Fix the first acquisition after power on.

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 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 fabe59b326 sr: drivers using sr_usb_dev_inst_new() must free it properly as well
sr_usb_dev_inst_free() doesn't really do anything, but it might one
day.

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 7da6f9d54a zeroplus-logic-cube: init and scan fixes
libusb context needs to be initialized only once, not ever scan.
Every scan invalidates the last one, so clean up any previous run's
results first.

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.
