I'm confused. Do I create 2 instances of a scale, or will it read 2 sensors with just one instance of Hx711?
Hx711 scaleA(2, 3); //2 sensors wired into a+ a- b+ b-
Hx711 scaleB(2, 3); //1 sensor wired into b+ b-
Hx711 scaleA(4, 5); //1 sensor wired into a+ a-
Also I read somewhere I have to set the gain on the B channel. I'm confused on this.
Is there a simple example script somewhere showing code for 2 load sensors?
