This DMM is not using the standard bits in the FS9922 protocol/structure
to indicate the "volt" and "diode mode" flags. Instead, it only sets the
user-defined bit "z1" to indicate both "diode mode" and "volt".
This fixes#142.
Since the uni-t-ut32x series handles devices with the same USB VID.PID,
which is linked to the WCH CH9325 USB/HID-UART interface chip, this
driver can no longer assume it can handle anything with this VID.PID.
The Tecpel DMM-8060 was added since we assumed it would be a rebadged
Voltcraft VC-820 (since we know the Tecpel DMM-8061 is a rebadged VC-840).
However, according to the vendor webpage it doesn't have PC connectivity
at all, so drop it for now (until someone can confirm that it does or does
not actually have RS232/USB connectivity).
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.
This invalidates previously returned sr_dev_inst pointers, which a
frontend may be holding. It's the frontend's responsibility to clear
the list of instances a driver keeps track of by calling
sr_dev_clear(driver);
if it wants a completely new scan done.
- Explicitly list .config_get in all drivers for consistency, and set it
to NULL if unused (whether or not a driver implements it is optional).
- List all 'struct sr_dev_driver' entries in the same order in all drivers.
- Move the check whether .config_set/.config_list exist (i.e., are non-NULL)
into sanity_check_all_drivers().
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.
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.
