50 File    : SEGGER_SYSVIEW_Conf.h
51 Purpose : SEGGER SystemView configuration file.
52           Set defines which deviate from the defaults (see SEGGER_SYSVIEW_ConfDefaults.h) here.
53 Revision: $Rev: 21292 $
54 
55 Additional information:
56   Required defines which must be set are:
57     SEGGER_SYSVIEW_GET_TIMESTAMP
58     SEGGER_SYSVIEW_GET_INTERRUPT_ID
59   For known compilers and cores, these might be set to good defaults
60   in SEGGER_SYSVIEW_ConfDefaults.h.
61 
62   SystemView needs a (nestable) locking mechanism.
63   If not defined, the RTT locking mechanism is used,
64   which then needs to be properly configured.
