#164810 - Table only needed if non-linear Responding to: ???'s previous message |
You only need a lookup table if the ADC is non-linear. Else, every bit will correspond to a number of mV or uV and you can then compute V = offset + ticks * scale. If the answer is in mV, then divide by 1000 to get integer volts. Modulo 1000 gives mV. |
