Joe Finney 13456c60c1 microbit: Removal of explicit Serial instance for debugging.
Debugging now runs via the standrad MicroBit::serial interface.

Joe Finney 1a65e4e7bc microbit: Added support for soft reset button in panic mode
Also recalibrated loop timers in MicroBitDisplay::Error(), as used by panic()...
strange these now seem off by several orders of magnitude.

TODO: Ensure CPU is running at correct internal frequency with an oscilloscope test...

Robert May b8083908a7 Correct warnings supression in more obvious way
Whilst a little more invasive change than the previous warnings
supression this is more correct and more obvious as to what's being done,
and what warnigns will remain in place for the rest of the comilation
unit.

Robert May 9591ef40dc Turn off -Wunused-parameter for include "nrf_soc.h"
Unfortunately we can't turn it off just while nrf_soc.h is being included
as the way the defines are used the compiler can't tell the parameters
are unused until the end of the compilation unit.  So we can't use the
more normal

as that pops the supression too early.

WARNING: including nrf_soc.h will turn off unused-function warnings for
the rest of the compilation unit - see included nrf_svc.h

Joe Finney b2e9369771 microbit: BUGFIX DoS attacks on the MessageBus
- Enures an event listener is not deleted whilst a fiber is activiely processing a queue

Joe Finney 84da6a4a09 microbit: Minor bug fixes and refinements

  - preservation of event ordering on messagebus for resursive event generation cases.
  - bugfix of message bus processing to prevent occasional dual processing of events
  - bugfix MicroBitDisplay to behave correctly when delay parameter is zero.

Joe Finney 7f64a4c703 microbit: BUGFIX Corrected incorrect handling of MicroBitMessageBus::add return values. 2015-10-26 16:37:12 +00:00
Joe Finney 823a956d68 microbit: First cut at updates to provide tight validation within the runtime code, with a view to moving
NOP/clamping behaviour out of teh micro:bit runtime and into the glue layers of higher level
languages.

 - Updates to many functions to provide explicut return codes.
 - Updates to many functions to remove heuristic calidation (NOP/clamping/defaults)
 - Updates to ErrorNo.h to provide clearer return values, and place return values in a better scope
 - Updates to MicroBitDisplay to use enums where appropriate.

Joe Finney db3eccf6ff microbit: Final updates to BLE profile
Minor changes to BLE profile services (cleanup prior to merge with master branch):

  - Added temperature period characteristic to match design pattern of other sensors.
  - Updated endinaness of MicroBitLEDService Matrix to be more intuitive.
  - Cleaned up Microbit.cpp by removing unused reference to BLE services.
  - Exposed serial number and naming information thr BLE DeviceInformation and API.
  - Updated BLE advertisement period to be alightly more repsonsive (200ms vs 1000ms).
  - BUGFIX: micro:bit name is now always generated, regardless of BLE services.
  - BUGFIX: Scroll Period data length.

Joe Finney ce2cc57bf1 microbit: Optimisation of internal Message Bus listeners
All message bus listeners with the micro:bit runtie are non blocking, and safe to be called
in an interrupt context. As such, these have now all been declared MESSAGE_BUS_LISTENER_IMMEDIATE
which should mitigate all unbounded event queueing effects.
