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 18236810a3 microbit: BLE Profile Beta 1
First functionally complete BLE profile, matching BLE speicfication v1.6.
More specifically, the following services are now functional:

  - AccelerometerService
  - MeganetometerService
  - EventService
  - TemperatureServide
  - IOPinService
  - DFUService
  - ButtonService
  - LEDService

Also, updates to underlying device drivers to enable greater configurability:

  - MicroBitCompass now supports variable sample rates and temperature sensing
  - MicroBitAccelerometer now supports variable sample rates and ranges
  - MicroBitThermometer introduced
  - MicroBitMessageBus adapted to permit enumeration and block removal of listeners

Finally, MicroBit DFU Service has been changed to the new UUIDs specificed in v1.6 of BLE spec.

Joe Finney ae0e5611c3 microbit: First draft of reconfigurable frequencies of MicroBitCompass 2015-09-19 21:00:38 +01:00
Joe Finney 9ccf0a7688 microbit: Added configuration support for accelerometer sample rate and range
MicroBitAccelerometer now contans methods to allow dynamic selection of sample range
(from +/-2g to +/-8g) and sample frequency (up to 800Hz). The default settings and behaviour
remain consistent.

Joe Finney 6470b71b1d microbit: Conditional compilation on MicroBitConfig
All options defined in MicroBitConfig are now set IFF they already do not have a value.
This allows external configuration of these options much more cleanly. Additional macros
also defined to provide clean implementation for boolean configuration switches.

Also some minor bugfixes:

  - Correction of typo of "Microbit.h" => "MicroBit.h"
  - Fixed heap corruption bug on gcc as a result of a debug printf in an unsafe context.
