File : Global.h
Purpose : Global types
In case your application already has a Global.h, you should
merge the files. In order to use Segger code, the types
U8, U16, U32, I8, I16, I32 need to be defined in Global.h;
additional definitions do not hurt.

File : SEGGER_SYSVIEW_Conf.h
Purpose : SEGGER SystemView configuration.
Revision: $Rev: 13453 $
Purpose : SEGGER SystemView configuration file.
Set defines which deviate from the defaults (see SEGGER_SYSVIEW_ConfDefaults.h) here.
Revision: $Rev: 21292 $
Additional information:
Required defines which must be set are:
SEGGER_SYSVIEW_GET_TIMESTAMP
SEGGER_SYSVIEW_GET_INTERRUPT_ID
For known compilers and cores, these might be set to good defaults
in SEGGER_SYSVIEW_ConfDefaults.h.
SystemView needs a (nestable) locking mechanism.
If not defined, the RTT locking mechanism is used,
which then needs to be properly configured.
