Uwe Hermann f1437c6814 serial-dmm: Use a macro for driver struct simplification. 2012-12-13 01:34:21 +01:00
Uwe Hermann 06b7a8af7e serial-dmm: Simplify code a bit.
Store/use the receive_data() function and a pointer to the driver struct
in the dmms[] array. Use a ".subdriver" entry in the driver struct.
Use a macro to simplify hw_init() wrappers.

Alexandru Gagniuc 5b389efcfe serial-dmm: Avoid duplicate symbol error
Declare dmm_info dmms as extern in protocol.h to prevent duplicate
symbol error from the linker.

Alexandru Gagniuc 26be4ebef3 serial-dmm: Fix segfault when no device is used
di was initialized as NULL. If no device covered by this driver
is used, di remains NULL. This causes a segmentation fault when
calling clear_instances().

Check for di being NULL.

Peter Stuge 123d97b177 backend.c: Fix memory leak in sr_init() error path
Commit 785b9ff290 added libusb init into
sr_init() which can generate an error. In this case, the already
allocated struct sr_context would have leaked.

Alexandru Gagniuc ae95ffebfa radioshack-dmm: Fix opening of serial port.
During scan the serial port is opened with SERIAL_RDONLY | SERIAL_NONBLOCK,
which works fine, but when acquisition starts, it is opened only with
SERIAL_RDONLY. On Linux, if cdc_acm can make a claim to the USB to serial
converter, opening the port will fail.

Open port with SERIAL_RDONLY | SERIAL_NONBLOCK.

Uwe Hermann eebb606762 demo: Add missing dev_clear() API call. 2012-12-02 17:21:13 +01:00
Uwe Hermann 55a6daf59f sr_init(): Add driver sanity checks.
After sr_init() has successfully run, we can be sure that all drivers
define all the API calls, so we don't have to do these checks later
in the individual API functions / wrappers.

If there are one or more drivers with missing API functions (or driver
name / longname, and so on), sr_init() will fail. This helps catch this
kind of developer error early on.

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.

strcmp(buf + 9, "  mA") does not work because buf is CR-terminated,

Drop ambiguities arising from the termination of the strings, and
only compare the characters we care about, using strncmp().

Alexandru Gagniuc 76b55dfa8a metex14: Fix parsing of spaces.
When the parser found a space, it treated it as an invalid digit
and discarded the whole packet. This behavior was incorrect on
2000 count devices, where the first digit can be sent as a space
rather than a '0'.

Convert spaces to '0' and parse them as usual.
