Voltage and data coding

voltage and data coding

This forum is intended for discussion of Particle products and services. I’d recommend trying an Arduino forum if your question is not related to Particle.

xVoltage = supplyVoltage*xReading/1024.;

FYI on a Particle device such as a Photon:

> The device has 8 channels (A0 to A7) with a 12-bit resolution. This means that it will map input voltages between 0 and 3.3 volts into integer values between 0 and 4095. This yields a resolution between readings of: 3.3 volts / 4096 units or, 0.0008 volts (0.8 mV) per unit.
