Other Parts Discussed in Thread: BQ76PL455EVM, HALCOGEN
Tool/software: Code Composer Studio
Hello everyone,
I am trying to develop a BMS algorithm on TMS570 with BQ76PL455EVM. I need to add a rti on the code to the sample code that has been presented by Texas Instruments.
extern void rtiCompare1Interrupt(void); extern void rtiCompare2Interrupt(void); extern void rtiCompare3Interrupt(void);
I have added code depicted above to sys_vim.h and code depicted below (rtiCompare1Interrupt, rtiCompare2Interrupt,rtiCompare3Interrupt, ) to sys_vim.c
static const t_isrFuncPTR s_vim_init[96U] =
{
&phantomInterrupt,
&esmHighInterrupt, /* Channel 0 */
&phantomInterrupt, /* Channel 1 */
&rtiCompare0Interrupt, /* Channel 2 */
&rtiCompare1Interrupt, /* Channel 3 */
&rtiCompare2Interrupt, /* Channel 4 */
&rtiCompare3Interrupt, /* Channel 5 */
&phantomInterrupt, /* Channel 6 */
&phantomInterrupt, /* Channel 7 */
&phantomInterrupt, /* Channel 8 */
.....
}
I have added below part to rt.c
*/
#pragma CODE_STATE(rtiCompare1Interrupt, 32)
#pragma INTERRUPT(rtiCompare1Interrupt, IRQ)
/* SourceId : RTI_SourceId_023 */
/* DesignId : RTI_DesignId_022 */
/* Requirements : HL_SR95 */
void rtiCompare1Interrupt(void)
{
/* USER CODE BEGIN (77) */
/* USER CODE END */
rtiREG1->INTFLAG = 2U;
rtiNotification(rtiNOTIFICATION_COMPARE1);
/* USER CODE BEGIN (78) */
/* USER CODE END */
}
/* USER CODE BEGIN (79) */
/* USER CODE END */
/** @fn void rtiCompare2Interrupt(void)
* @brief RTI1 Compare 2 Interrupt Handler
*
* RTI1 Compare 2 interrupt handler
*
*/
#pragma CODE_STATE(rtiCompare2Interrupt, 32)
#pragma INTERRUPT(rtiCompare2Interrupt, IRQ)
/* SourceId : RTI_SourceId_024 */
/* DesignId : RTI_DesignId_022 */
/* Requirements : HL_SR95 */
void rtiCompare2Interrupt(void)
{
/* USER CODE BEGIN (80) */
/* USER CODE END */
rtiREG1->INTFLAG = 4U;
rtiNotification(rtiNOTIFICATION_COMPARE2);
/* USER CODE BEGIN (81) */
/* USER CODE END */
}
/* USER CODE BEGIN (82) */
/* USER CODE END */
/** @fn void rtiCompare3Interrupt(void)
* @brief RTI1 Compare 3 Interrupt Handler
*
* RTI1 Compare 3 interrupt handler
*
*/
#pragma CODE_STATE(rtiCompare3Interrupt, 32)
#pragma INTERRUPT(rtiCompare3Interrupt, IRQ)
/* SourceId : RTI_SourceId_025 */
/* DesignId : RTI_DesignId_022 */
/* Requirements : HL_SR95 */
void rtiCompare3Interrupt(void)
{
/* USER CODE BEGIN (83) */
/* USER CODE END */
rtiREG1->INTFLAG = 8U;
rtiNotification(rtiNOTIFICATION_COMPARE3);
/* USER CODE BEGIN (84) */
/* USER CODE END */
}
and added below part to notification.c
#pragma WEAK(rtiNotification)
void rtiNotification(uint32 notification)
{
if ( notification == rtiNOTIFICATION_COMPARE0)
{
printf("SELAM \r\n");
}
else if ( notification == rtiNOTIFICATION_COMPARE1)
{
RTI_TIMEOUT = 1;
}
else if ( notification == rtiNOTIFICATION_COMPARE2)
{
printf("HOP \r\n");
}
else if ( notification == rtiNOTIFICATION_COMPARE3)
{
printf("HOP \r\n");
}
/* enter user code between the USER CODE BEGIN and USER CODE END. */
/* USER CODE BEGIN (9) */
/** - Clear all pending interrupts */
//rtiREG1->INTFLAG = 0x0007000FU;
//RTI_TIMEOUT = 1;
/* USER CODE END */
}
My interrupts are now working but now I can not read voltage value etc from BQ76PL455EVM. All readings are 0. When I revert code to the previous version. It works again but on that condition I do not have any timer interrupt.
Min Cell : 1 , Voltage : 0.000000
Max Cell : 0 , Voltage : 0.000000
Pack Voltage= 0.000000
What may be wrong. How can I solve that problem?
Thanks.
