Analog Read dummy file Can we use just a analog Read without storing it
i hear it it a good practice to take two reads
for better accuracy
example:
// Read extra analog inputs
    for (int i = 0; i &lt; 8; i++)
{
    // Read analog pin to nothing.
        analogRead(i]); // analog-read is not writing to anything 
}


// Read the analog inputs
for (int i = 0; i &lt; length; i++)
{
    // Write the state of the analog pin to the response buffer.
    slave.writeRegisterToBuffer(i, analogRead(analog_pins[address + i]));
}
how about this ?
// Read the analog inputs
for (int i = 0; i &lt; length; i++)
{
    analogRead(analog_pins[address + i]); // for pre read

    // Write the state of the analog pin to the response buffer.
    slave.writeRegisterToBuffer(i, analogRead(analog_pins[address + i]));
}
