arduino 2 weight sensor (count as one)

Using Arduino Sensors
#1

hi there,

i have 2 sensors and one placket hx711

i need help how to connect 2 weight sensor on ones hx711 placket and count as one.

With one weight sensor i uses this code and work correctly :

#include "HX711.h"
HX711 scale(A1, A0); // DOUT, SCK

void setup()
{
Serial.begin(9600);
scale.set_scale(2280.f); //// this value is obtained by calibrating the scale with known weights
scale.tare();
}

void loop()
{
Serial.print("one reading:\t");
Serial.print(scale.get_units(), 1);
scale.power_down(); // put the ADC in sleep mode
delay(5000);
scale.power_up();
}/quote]

It's possible to use both channels (but channel B with a gain of 32, while ch. A has a gain of 128).
Looks like you can use the function "set_gain(nn)" with parameter 32 to read ch. B
(gain 64 or 128 for ch. A)

i did it with RPi using python but when i try with arduino i get same value even if on cell has no weight on it can you show me the code please
