Other Parts Discussed in Thread: ADS1230
Dear Bob,
As from your information i tried different averaging techniques for adc.And finally i tried one moving average method it seems fine and easy.It uses floating point.But i need your suggestion to know,that how much efficient it is.My averaging looks like:
long mov_avg(void)
{
ave_data=datas(); //updated ADC value(new sample);
diff=(ave_data - run_avg)/4; //diff is a float datatype(run_avg is previous average);
run_avg += diff; //adding or subtracting the difference to or from run_avg;
ave_data = run_ave; //ave_data is an int datatype;
return(ave_data);
}
This program take much settling time.So i think the "run_avg" need to replace with current sample if there is a large step change,am i right.But how much difference should i take.So if i m taking the difference should i include the "standard deviation" of ADC.Then what is the "standard deviation" for ADS1230.
Please give me some suggestions,..expecting your valuable reply..
Thank you
