using channel A + B together? about hx711

[bogde]

read the datasheet to see what i mean about the clock pin. you need to pulse it 24 times to get one reading (24 bits).

// set the gain factor; takes effect only after a call to read() // channel A can be set for a 128 or 64 gain; channel B has a fixed 32 gain // depending on the parameter, the channel is also set to either A or B void set_gain(byte gain = 128); so use set_gain(32); to select the second channel, then read it. you can't read both channels at the same time. read the datasheet. then, use: set_gain(128); // or just set_gain(); to select the first channel, and read it.
