Merge branch 'master' into scanwidget 

* master: (38 commits)
  hardware_testbench: better message when skipping
  test_spi: drain errors and be more strict on where we expect errors
  monkey-patch asyncio.proactor_events to handle ConnectionAbortedError on Windows. Closes #247
  test/rtio/Loopback: ensure loop_out is low before starting test
  test/rtio: raise exception when pulse is not received
  rtio: fix different address collision detection
  frontend/coreanalyzer: do not attempt to print obsolete decoded_dump attribute. Closes #324
  coredevice: put cache into separate file/device
  gui: delete log/applet docks instead of hiding them
  gui/moninj: make DDS widgets look less like buttons
  rtio: remove NOP suppression capability
  rtio/wishbone: make replace configurable
  exceptions: clarify RTIOBusy
  gateware/rtio: factor _BlindTransfer
  test_spi: break_realtime
  test_spi: simplify test, add collision vs busy test
  hardware_testbench: clean up artiq_core_exeption printing
  coredevice: fix _DDSGeneric __init__ args
  hardware_testbench: also print artiq_core_exeption
  rtio/core: fix syntax

@ -11,4 +11,8 @@ Release notes
This requires reflashing the runtime and the flash storage filesystem image
or erase and rewrite its entries.
* RTIOCollisionError has been renamed to RTIOCollision
* the new API for DDS batches is:
with self.core_dds.batch:
...
with core_dds a device of type artiq.coredevice.dds.CoreDDS.
The dds_bus device should not be used anymore.

The input only limitation on channels 0 and 1 comes from the QC-DAQ adapter. When the adapter is not used (and physically unplugged from the Pipistrello board), the corresponding pins on the Pipistrello can be used as outputs. Do not configure these channels as outputs when the adapter is plugged, as this would cause electrical contention.
