NAME¶
comedi_to_physical - convert sample to physical units using polynomialsSYNOPSIS¶
#include <comedilib.h>
double comedi_to_physical(lsampl_t data,
const comedi_polynomial_t * conversion_polynomial);
DESCRIPTION¶
Converts data given in Comedi's integer sample values ( lsampl_t, between 0 and maxdata) into physical units ( double). The conversion_polynomial parameter is obtained from either comedi_get_hardcal_converter or comedi_get_softcal_converter. No range checking of the input data is performed. It is up to you to check for data values of 0 or maxdata if you want to detect possibly out-of-range readings.RETURN VALUE¶
Physical value corresponding to the input sample value.AUTHORS¶
