[Rev 44] changelog: This is a complete refactoring of the mbed library to move the target dependent code to a thin well defined layer, defining a proper object oriented C API.

  • Remove RTTI
  • Remove Base class.
  • Move RPC to a separate open source library.
  • Introduce MIT license file header
  • Properly define an Object Oriented C API.
  • Move parameter type definitions from the C++ layer to the C API.
  • Move target dependent logic from the C++ layer to the C layer.
  • Separate C API implementations by silicon vendor.
  • Move SerialHalfDuplex and SPIHalfDuplex to a separate library.

API Changes

Revision 44 is a complete refactoring of the mbed library to move the target dependent code to a thin well defined layer, defining a proper object oriented C API. This introduced few minor changes to the mbed API:

  • We moved the RPC logic in a separate library. Now the RPC class is not the base class of every mbed library class, for this reason the constructors do not take any more an optional "char* name" argument. If you are getting a compilation error of the type "No instance of constructor mbed::ClassName::ClassName" matches the argument list, you probably just need to drop the name parameter.
  • The protected Serial class member int _uidx; is now a field of the serial_t structure: serial_t _serial;. 

_uidx -> _serial.index

[Rev 43] changelog:

  • Update CMSIS core to V3.0

[Rev 40-42] changelog:

  • Move export toolchain builds

Build System Change

Starting from these revisions the build system builds C files as C syntax and C++ files as C++ syntax. See: Compile C as C and C++ as C++

If updating the mbed library you get "odd" compilation errors about unidentified C++ keywords (like: "identifier namespace is undefined"), you have a quick and simple fix: rename your "*.c" file to "*.cpp".

[Rev 39] changelog:

  • Make sure stdio retargeting gets always linked in, even when no other symbol from the mbed library is used.

[Rev 38] changelog:

  • Fix a M0 sleep bug (properly track if the interface chip is attached)

[Rev 37] changelog:

  • Revert few system configuration changes from "system_LPC17xx.c"

[Rev 36] changelog:

  • Fix SPI set frequency rounding

[Rev 35] changelog:

  • Move CAN::attach template implementation to header.
  • CMSIS v3 updates

[Rev 34] changelog:

  • API to directly access the local file system without passing through the C standard library file system (unbuffered in the microlib).

[Rev 33] changelog:

  • Fix I2C set frequency bug
  • Fix mbed_interface_reset bug
  • Update LPC11U24/core_cm0.h to latest CMSIS version

[Rev 32] changelog:

[Rev 31] changelog:

  • Add M0 implementations of:
    • PortIn, PortOut and PortInOut
    • RPC support
    • PwmOut
  • Bugfix in stdio retargeting for GCC toolchains: avoid resetting the baud of UART0 if it is already initialized

[Rev 29] changelog: This release of the library introduce support for new toolchains and a new target:

  • LPC11U24 (Cortex-M0) support
  • Multiple toolchain support:
    • ARM compiler with standard libraries
    • ARM compiler with a version of the microlib libraries patched to support C++
    • CodeSourcery GCC
    • CodeRed GCC
