Other Parts Discussed in Thread: HALCOGEN
Tool/software:
Hello,
We are new to the TMS570 RTI programming. We have configured, via HalCoGen (and generated code accordingly), the RTI as:
In our software running on the LaunchPad TMS570LC43x, after calling the 'rtiInit()' and '_enable_IRQ()' functions, we have the code as following:
void delayus(uint16 us)
{
if (us == 0)
return;
else
{
//CHANGE THE INTERRUPT COMPARE VALUES (PERIOD OF INTERRUPT)
//Setup compare 1 value.
rtiREG1->CMP[1U].COMPx = 10*us; //10 ticks of clock per microsecond, so multiply by 10
//Setup update compare 1 value.
rtiREG1->CMP[1U].UDCPx = 10*us;
//ENABLE THE NOTIFICATION FOR THE PERIOD WE SET
rtiEnableNotification(rtiREG1, rtiNOTIFICATION_COMPARE1);
//START THE COUNTER
rtiStartCounter(rtiREG1, rtiCOUNTER_BLOCK0);
//WAIT IN LOOP UNTIL THE INTERRUPT HAPPENS (HAPPENS AFTER THE PERIOD WE SET)
//WHEN INTERRUPT HAPPENS, RTI_NOTIFICATION GETS SET TO 1 IN THAT INTERRUPT
//GO TO notification.c -> rtiNotification() to see where RTI_TIMEOUT is set to 1
while(RTI_TIMEOUT==0);
//RESET THE VARIABLE TO 0, FOR THE NEXT TIME WE DO A DELAY
RTI_TIMEOUT = 0;
//DISABLE THE INTERRUPT NOTIFICATION
rtiDisableNotification(rtiREG1, rtiNOTIFICATION_COMPARE1);
//STOP THE COUNTER
rtiStopCounter(rtiREG1, rtiCOUNTER_BLOCK0);
//RESET COUNTER FOR THE NEXT TIME WE DO A DELAY
rtiResetCounter(rtiREG1, rtiCOUNTER_BLOCK0);
}
}
However, at run-time, we observed the software stuck at "while(RTI_TIMEOUT==0);", in other words, the 'rtiNotification' never gets executed with "rtiNOTIFICATION_COMPARE1" as one of its input parameters.
Please advise. Thank you.
John
