Low Level Interrupt Control Problem

Question

Posted on November 04, 2014 at 12:58

Hello, 
 I'm trying register base interrupt control. But not working.(problem *.s files) 
 
 I do not 
 want to use to OSAL library.
 Not starting interrupt.
 Example Code:
 
 //Orhan YILMAZ
//Timer Example
typedef
enum
{
FALSE,
TRUE
}
BOOL
;
void
StartupInit(
void
);
void
Port_conig(
void
);
void
WDT_disable(
void
);
void
PIT0_Init(unsigned 
int
TimeOut);
void
PIT0_Start(
void
);
//void PIT_0_Handler(void);
void
Interrup_Enable(
void
);
#include ''components.h''
#include ''xpc560b.h''
/*
* Application entry point.
*/
unsigned 
long
i = 0;
int
main(
void
) {
componentsInit();
//CLK Init.
StartupInit();
//WDT Disable
WDT_disable();
//Port
Port_conig();
//Timer
PIT0_Init(0xFFFFF);
//IRQ Config
Interrup_Enable();
PIT0_Start();
while
(TRUE) {
if
(i == 0xFFFFFF)
{
//SIU.GPDO[90].B.PDO ^= 1;
i = 0;
}
i++;
}
}
//PORT CONFIGURATION
void
Port_conig(
void
)
{
//Working Led
SIU.PCR[90].B.OBE = 1;
SIU.GPDO[90].B.PDO = 0;
//Output Low
}
//PIT0 Initial Function
void
PIT0_Init(unsigned 
int
TimeOut)
{

PIT.PITMCR.R = 0x000000001;
//Enable PIT and Configure to stop in debug mode
PIT.CH[0].LDVAL.R = TimeOut;
//Timeout enter
//Tclk = SystemCLK
INTC_PSR(PIT0_VECTOR)=5;
//PIT_0_Handler, 59, 5;
IRQ_HANDLER(PIT_0_Handler);
}
//PIT0 Start Function
void
PIT0_Start(
void
)
{
//TIE = 1 Timer Interrup Enable
//TEN = 1 Timer Enable
PIT.CH[0].TCTRL.R = 3;
}
void
WDT_disable(
void
)
{
//Watchdog Timer Disable
SWT.SR.R = 0x0000c520; 
/* Write keys to clear soft lock bit */
SWT.SR.R = 0x0000d928;
SWT.CR.R = 0x8000010A; 
/* Clear watchdog enable (WEN) */
}
/*************************
*CLK CONFIGURATION
*************************/
void
StartupInit(
void
)
{ 
  *
 *
 *
 *
 *
 *
 *
 *
 
 //Check Configurations
while
(ME.GS.B.MTRANS);
//Global Status Register wait for mode transition to complete
while
(ME.GS.B.CURRENTMODE != 4);
//Global Status Register verify RUN0 Current mode
}
//*********IRQ***********//
void
Interrup_Enable(
void
)
{
INTC.CPR.B.PRI = 0; 
// Lower INTC's current priority
asm(
''wrteei 1''
); 
//Enable external interrupt ================>>> PROBLEM THIS LINE
}
void
PIT_0_Handler(
void
)
{
PIT.CH[0].TFLG.B.TIF = 1;
SIU.GPDO[90].B.PDO ^= 1;
} 
 Note: ivor.s and vector.s copy my project folder.
 
 Thanks.

Posted on November 14, 2014 at 13:52 Hello Orhan ,   Do you want enable PIT 0 Channel handler ?  if yes , you have to update your application  and use the vector59 (Channel PIT 0)  your vector59 handler is already defined in hal_lld.c.   if you want to customize it  stub ''hal_lld.c '' by using PATCH MODE FEATURE in SPC5Studio 3.3  Example Code hal_lld.c :    /*** @brief PIT channel 0 interrupt handler.** @isr*/#if 0OSAL_IRQ_HANDLER(vector59) {OSAL_IRQ_PROLOGUE();osalSysLockFromISR();osalOsTimerHandlerI();osalSysUnlockFromISR();/* Resets the PIT channel 0 IRQ flag.*/PIT.CH[0].TFLG.R = 1;OSAL_IRQ_EPILOGUE();}#endif   Example Code main.c (cf below) V2.0:  you can see the LED is blinking when the interruption PIT0 happenned   //Orhan YILMAZ v2.0 (Updated by Erwan)//Timer Exampletypedefenum{FALSE,TRUE}BOOL;#define PIT0_VECTOR 59voidStartupInit(void);voidPort_conig(void);voidWDT_disable(void);voidPIT0_Init(unsigned intTimeOut);voidPIT0_Start(void);staticvoidPIT_0_Handler(void);/*** @brief IRQ handler function declaration.* @details This macro hides the details of an ISR function declaration.** @param[in] id a vector name as defined in @p vectors.s*/#define IRQ_HANDLER(id) void id(void)voidInterrup_Enable(void);#include ''components.h''#include ''xpc560b.h''/** Application entry point.*/unsigned longi = 0;intmain(void) {componentsInit();//CLK Init.StartupInit();//WDT DisableWDT_disable();//PortPort_conig();//TimerPIT0_Init(0xFFFFF);//IRQ ConfigInterrup_Enable();PIT0_Start();while(TRUE) {if(i == 0xFFFFFF){//SIU.GPDO[90].B.PDO ^= 1;i = 0;}i++;}}//PORT CONFIGURATIONvoidPort_conig(void){//Working LedSIU.PCR[90].B.OBE = 1;SIU.GPDO[90].B.PDO = 0;//Output Low}//PIT0 Initial FunctionvoidPIT0_Init(unsigned intTimeOut){PIT.PITMCR.R = 0x000000001;//Enable PIT and Configure to stop in debug modePIT.CH[0].LDVAL.R = TimeOut;//Timeout enter//Tclk = SystemCLKINTC_PSR(PIT0_VECTOR)=5;//PIT_0_Handler, 59, 5;}/*** @brief PIT channel 0 interrupt handler.** @isr*/IRQ_HANDLER(vector59) {PIT_0_Handler();}//PIT0 Start FunctionvoidPIT0_Start(void){//TIE = 1 Timer Interrup Enable//TEN = 1 Timer EnablePIT.CH[0].TCTRL.R = 3;}voidWDT_disable(void){//Watchdog Timer DisableSWT.SR.R = 0x0000c520; /* Write keys to clear soft lock bit */SWT.SR.R = 0x0000d928;SWT.CR.R = 0x8000010A; /* Clear watchdog enable (WEN) */}/**************************CLK CONFIGURATION*************************/voidStartupInit(void){//Check Configurationswhile(ME.GS.B.MTRANS);//Global Status Register wait for mode transition to completewhile(ME.GS.B.CURRENTMODE != 4);//Global Status Register verify RUN0 Current mode}//*********IRQ***********//voidInterrup_Enable(void){INTC.CPR.B.PRI = 0; // Lower INTC's current priorityasm(''wrteei 1''); //Enable external interrupt ================>>> PROBLEM THIS LINE}staticvoidPIT_0_Handler(void){PIT.CH[0].TFLG.B.TIF = 1;SIU.GPDO[90].B.PDO ^= 1;palTogglePad(PORT_E, PE_LED1);}  Best Regards   Erwan
