Full HAL functions common across all microcontroller-specific files. See Common Microcontroller Functions for documentation.

Some functions in this file return an EmberStatus value. See error-def.h for definitions of all EmberStatus return values.

Macros#

#define
halGetEm2xxResetInfo ()

Calls ::halGetExtendedResetInfo() and translates the EM35x reset code to the corresponding value used by the EM2XX HAL. Any reset codes not present in the EM2XX are returned after being OR'ed with 0x80.

Functions#

void
halStackProcessBootCount(void)

Called from emberInit and provides a means for the HAL to increment a boot counter, most commonly in non-volatile memory.

uint8_t
halGetResetInfo(void)

Gets information about what caused the microcontroller to reset.

PGM_P
halGetResetString(void)

Calls halGetResetInfo() and supplies a string describing it.

Macro Definition Documentation#

halGetEm2xxResetInfo#

#define halGetEm2xxResetInfo
Value:
()

Calls ::halGetExtendedResetInfo() and translates the EM35x reset code to the corresponding value used by the EM2XX HAL. Any reset codes not present in the EM2XX are returned after being OR'ed with 0x80.

  • Application Usage:\n Used by the EZSP host as a platform-independent NCP reset code.#

Returns

  • The EM2XX-compatible reset code. If not supported by the EM2XX, return the platform-specific code with B7 set.

Function Documentation#

halStackProcessBootCount#

void halStackProcessBootCount (void )

Called from emberInit and provides a means for the HAL to increment a boot counter, most commonly in non-volatile memory.

Parameters
N/A

This is useful while debugging to determine the number of resets that might be seen over a period of time. Exposing this functionality allows the application to disable or alter processing of the boot counter if, for example, the application is expecting a lot of resets that could wear out non-volatile storage or some

  • EmberStack Usage:\n Called from emberInit only as helpful debugging information.#

    This should be left enabled by default, but this function can also be reduced to a simple return statement if boot counting is not desired.


Definition at line 68 of file /mnt/raid/workspaces/ws.2dqDELv9z/overlay/gsdk/platform/base/hal/micro/micro.h

halGetResetInfo#

uint8_t halGetResetInfo (void )

Gets information about what caused the microcontroller to reset.

Parameters
N/A

Returns

  • A code identifying the cause of the reset.


Definition at line 74 of file /mnt/raid/workspaces/ws.2dqDELv9z/overlay/gsdk/platform/base/hal/micro/micro.h

halGetResetString#

PGM_P halGetResetString (void )

Calls halGetResetInfo() and supplies a string describing it.

Parameters
N/A

  • Application Usage:\n Useful for diagnostic printing of text just after program#

    initialization.

Returns

  • A pointer to a program space string.
