nexus-osciprime: basic scanning functionality

Unfortunately the device doesn't have an EEPROM on board at all, and so
initially enumerates with the default Cypress FX2 VID:PID (04b4:8613).
Since we already support using plain FX2* as basic logic analyzers using
the fx2lafw firmware, we cannot support that same VID:PID for the
OsciPrime. Therefore a USB conn is required for the initial scan.

However, once the firmware is uploaded the device re-enumerates as
04b4:1004, which we do detect for scanning automatically.

Thus, the OsciPrime driver requires one scan with conn parameter to get
the firmware uploaded, but it will then keep working until powered off.

11 years agoserial-dmm: Use dummy info struct for rs9lcd parser

serial-dmm: Use dummy info struct for rs9lcd parser

The rs9lcd parser, which is used for the RadioShack 22-812 does not use its
*info parameter, and therefore did not have a rs9lcd_info struct declared.

With recent re-factoring of the receive data callbacks, it became necessary to
pass a struct pointer. This made the RECV_DATA macro look like:

- RECV_DATA(RADIOSHACK_22_812, metex14)

giving the wrong impression that the RadioShack 22-182 uses the
metex14 protocol, which is not the case.

Create a dummy rs9lcd_info struct, and correctly identify the parser
as rs9lcd in the RECV_DATA macro:

+ RECV_DATA(RADIOSHACK_22_812, rs9lcd)

The sr_dev_driver struct is available to the frontend. Exposing the subdriver
field creates the problem of exposing knowledge of libsigrok's internal driver
layout, even though the drivers are designed to be a flat list to the frontend.

serial-dmm: Remove global sr_dev_driver *di alias

The global *di alias was used to keep track of the driver context.
It caused issues with trying to use several subdrivers at once, so
its use was obsoleted.

The correct context is preserved through different mechanisms, either
the *sdi pointer, or wrappers which pass the correct context.

The *di alias is no longer used, so remove it.

11 years agoserial-dmm: Simplify wrapper layout
Alexandru Gagniuc [Thu, 13 Dec 2012 14:58:01 +0000 (08:58 -0600)]
serial-dmm: Simplify wrapper layout

Wrappers for hw_init, hw_cleanup, clear_instances, and hw_scan are needed for
each subdriver due to the nature of serial-dmm. These wrappers are implemented
as macros, in order to reduce the number of lines of code.

For each of those functions, we have a separate wrapper list, then we connect
them together in a first-class driver using a DRV macro, and yet another list
(the DRV list).

Instead of declaring those wrappers in separate lists, include them in the DRV
macro. This approach reduces the number of macro lists from five to just one.

From the perspective of adding a new subdriver, this also greatly reduces the
number of places needed to hook in a new device.
