Hello,

I am trying to work on RM48 L950 rti blinky project.

#include "rti.h"
#include "het.h"
#include "gio.h"

void main(void)
{

rtiInit();

gioSetDirection(hetPORT1, 0xFFFFFFFF);

rtiEnableNotification(rtiNOTIFICATION_COMPARE0);

_enable_IRQ();

rtiStartCounter(rtiCOUNTER_BLOCK0);

while(1);

}

void rtiNotification(uint32 notification)
{

gioToggleBit(hetPORT1, 0x00000001);

rtiStopCounter(rtiCOUNTER_BLOCK0);

while(!rtiResetCounter(rtiCOUNTER_BLOCK0));

rtiStartCounter(rtiCOUNTER_BLOCK0);

}

After debugging this code,there is no error.But the the LEDs are not blinking as expected.Please help me to fix this issue.

Thanks in advance

What do you mean by “not blinking as expected”? RTI is usually configured once to generate a periodic interrupt, within which you can toggle a pin. You don’t need to stop, reset and restart an RTI counter within an ISR. Run the above code with just the gioToggleBit() function call in the ISR.

I mean LEDs should be turned ON and OFF after certain period of time because of counter. But LEDs glow only once after pressing reset button and then turn OFF till I press reset again.

As I mentioned, please run the code with just the GIO toggle function in the rtiNotification().

Sir,it didn't work. Do I need to change anything in HALCoGen? I am following the examples in Help section of HALCoGen.

Hello,

As Sunil said, just run the code for toggling GIO pin. Please remove the code for stop/reset/restart counter0. The LED will be turn on/off periodically.
