| unsigned short CADC2530::getULD | ( | ) |
Get the ULD value.
Get the upper level discriminator (ULD) DAC value. The value returned is NOT a voltage but the computed DAC value as described the ADC manual. This value can be computed from the desired voltage (per the manual) as:
ULD DAC value = ((((Vreq/3.2764)-2)/(0.25/4095))<<2)&0x3FFC
The value return by this method is the computed "ULD DAC value."
