CCS/TMS320F28335: ADC Interrupt and CPU Timer 0 interrupt not working together in same code

Hi Hareesh,

Thanks for your support.

Actually  I am integrating couple of things in my code for example (ADC, DMA, TIMER Interrupt and

sineAnalyzerWithPowerMeas digital power library functions ). When I tried to comment the portion of functions for sineAnalyzerWithPowerMeas the Timer interrupt is working fine even after flashing the code and in debug mode as well. But if I call some functions in main code the timer interrupt does not work. 

Below are the mentioned functions that I am calling from main and those functions definitions are written in separate file with name  sineAnalyzerWithPowerMeas.c and sineAnalyzerWithPowerMeas.h.

////////////////////////////////////////////////////snip of main code////////////////////////////

sineAnalyzerWithPowerMeas_init(&sine_mains);

sine_mains.sampleFreq = (float32)(ISR_CONTROL_FREQUENCY);

sine_mains.threshold = (float32)(0.00);

sine_mains.nSamplesMax=ISR_CONTROL_FREQUENCY/UNIVERSAL_GRID_MIN_FREQ;

sine_mains.nSamplesMin=0;

sine_mains.emaFilterMultiplier=2.0/ISR_CONTROL_FREQUENCY;

sine_mains.nSamples=0;

sine_mains.nSamplesMax=MAX_SAMPLE;

// while(1) loop In main code 

for(;;)

{

if(rmsflag==1)

{

sine_mains.v = ((float)Voltage1[sine_mains.nSamples]*3/4095)-0.5;

sineAnalyzerWithPowerMeas_calc(&sine_mains);

rmsflag=0;

}

}

}

This functions are basically used for sine wave measurements like(average, RMS of current and voltages).

I am not understanding why timer interrupt is not working if  I use above functions in main code. Is there any problem with initialization. Please help with the same.

Thanks,

Namita
