Tool chain used for build

The following tools have been used:


Compiler:  IAR ICCSTM8   1.30.1 (1.30.1.50036)
Assembler: IAR IASMSTM8  1.30.1 (1.30.1.50036)
Librarian: IAR IARCHIVE  9.9.2.31
Workbench: IAR IARIDEPM  6.0.4.1683

Performance

  1. Task switch time
    < 23us
  2. Interrupt latency for Fast interrupt
    zero

New features

Version 3.86i

  1. New generic embOS functions
    embOS version 3.86i comes with new functions described in the generic manual and release notes.

Version 3.82k

  1. New generic embOS functions
    embOS version 3.82k comes with new functions described in the generic manual and release notes.

Version 3.82h

  1. NONE, Initial release
    This initial release of embOS STM8 for IAR compiler is based on embOS sources 3.82h.

Improvements

Version 3.82h

  1. NONE, Initial release
    This initial release of embOS STM8 for IAR compiler is based on embOS sources 3.82h.

Program corrections

Version 3.82m

  1. OS queue management corrected
    The embOS generic queue management did not work correctly.
    The problem existed since version 3.82k of embOS and is corrected with version 3.82m.

Version 3.82h

  1. NONE, Initial release
    This initial release of embOS STM8 for IAR compiler is based on embOS sources 3.82h.

Known problems / Limitations

Version 3.82h

  1. Small data memory model not supported.
    The small data memory model per default allows a total amount of RAM of 256 bytes.
    As this is does not make much sense for usage with embOS, the small data memory is not supported.
  2. Large data memory model not supported.
    The large data memory model is not supported by embOS because memory addressing above the 64KB address range ist not very efficient and normally not needed.
