Subject:	multiple interrupt callback for waveform record
From:	"Vishnu Patel" <[email protected]>

Hi,

In my asynDriver based driver, i am acquiring 100 data points in the poling mode and then call interrupt callback for waveform record for each channel.

If i keep my NELM field more than 100 in the application waveform record, it works fine and i am not loosing any data. but if application have waveform record NELM less then 100, i am loosing data.

I tried to run loop for calling interrupt call back function upto 100 data points over but it seems it doesn't call callback after once called. and need end and restart interrupt.

The way i am calling interrupt is as below with addr=channel number.

if (interrupt[addr]) {

p_interruptFloat32Array->pasynUser->auxStatus = interrupt_status[addr];

p_interruptFloat32Array->callback(p_interruptFloat32Array->userPvt,

p_interruptFloat32Array->pasynUser, buffer[addr], threshold);

}

Do any one doing multiple callback for same channel till all the buffered data pushed out to waveform record with same interrupt node?

Thanks

Vishnu
