File : SEGGER_SYSVIEW_Config_embOS_RX.c
|
|
Purpose : Sample setup configuration of SystemView with embOS
|
|
on Renesas RX systems.
|
|
Revision: $Rev: 21298 $
|
|
|
|
Additional information:
|
|
SEGGER_SYSVIEW_TickCnt must be incremented in the SysTick
|
|
handler before any SYSVIEW event is generated.
|
|
|
|
Example in embOS RTOSInit.c:
|
|
|
|
void SysTick_Handler(void) {
|
|
#if (OS_PROFILE != 0)
|
|
SEGGER_SYSVIEW_TickCnt++; // Increment SEGGER_SYSVIEW_TickCnt before calling OS_INT_EnterNestable().
|
|
#endif
|
|
OS_INT_EnterNestable();
|
|
OS_TICK_Handle();
|
|
OS_INT_LeaveNestable();
|
|
}
