I have problem to make any interrupt to work.
I tried many sample codes, but none of them work.
CODE for external interrupt P3.2
SCU_APBPeriphReset(__VIC, DISABLE);
SCU_APBPeriphReset(__WIU, DISABLE);
SCU_APBPeriphReset(__GPIO3, DISABLE);
SCU_APBPeriphReset(__RTC, DISABLE);
SCU_AHBPeriphClockConfig(__VIC, ENABLE);
SCU_APBPeriphClockConfig(__WIU, ENABLE);
SCU_APBPeriphClockConfig(__GPIO3, ENABLE);
SCU_APBPeriphClockConfig(__RTC, ENABLE);
WIU_DeInit();
WIU_InitTypeDef WIU_InitStructure;
WIU_Cmd(ENABLE );
WIU_ClearITPendingBit(WIU_Line26);
WIU_StructInit(&WIU_InitStructure);
WIU_InitStructure.WIU_Line = WIU_Line26 ;
WIU_InitStructure.WIU_TriggerEdge = WIU_FallingEdge ;
WIU_Init(&WIU_InitStructure);
// Select WIU line 26 as VIC1.10 interrupt source
SCU_WakeUpLineConfig(26);
VIC_DeInit();
// Initialize VICs Default vector address registers
VIC_InitDefaultVectors();
// Configure the External interrupt group 0 priority
VIC_Config(EXTIT0_ITLine, VIC_IRQ, 0);
// Enable the External interrupt group 0
VIC_ITCmd(EXTIT0_ITLine, ENABLE);
//#################### BUTTONS ####################
// Configure PORT3 lines in Input Push-Pull mode
GPIO_DeInit(GPIO3);
GPIO_StructInit(&GPIO_InitStructure);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2 | GPIO_Pin_3 | GPIO_Pin_4 | GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7;
GPIO_InitStructure.GPIO_Direction = GPIO_PinInput;
GPIO_InitStructure.GPIO_Type = GPIO_Type_PushPull ;
GPIO_Init(GPIO3, &GPIO_InitStructure);
//buttons normally HIGH
########################################################
Another example for RTC:
RTC_DeInit();
RTC_PeriodicIntConfig(RTC_Per_2Hz);
RTC_TamperCmd(DISABLE);
RTC_AlarmCmd(DISABLE);
RTC_ITConfig(RTC_IT_Per, ENABLE);
RTC_ITConfig(RTC_IT_Alarm, DISABLE);
RTC_ITConfig(RTC_IT_Tamper, DISABLE);
RTC_ClearFlag(RTC_FLAG_Per|RTC_FLAG_Per|RTC_FLAG_Tamper);
VIC_DeInit();
VIC_Config(RTC_ITLine, VIC_IRQ, 1);
VIC_ITCmd(RTC_ITLine, ENABLE);
/////////////
The same with Timers....
No IRQHandler() is called... for any source!
This is a part of bigger project...
Maybe I forgot about some configuration or there is special action needed in CrossWorks...
Has anybody some examples working with CrossWorks 1.7
Sorry for english
