comedi_to_physical — convert sample to physical units using polynomials
#include <comedilib.h>
double comedi_to_physical( | lsampl_t data, |
const comedi_polynomial_t * conversion_polynomial); |
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.
