Hi,

I had to take a look at the datasheet but it seems to be indeed possible in the current code (although not very well documented):
According to https://cdn.sparkfun.com/datasheets/Sensors/ForceFlex/hx711_english.pdf you can select the channel and gain by specifying the number of clock bits. You can have the following configurations:

PD_SCK Pulses	Input channel	Gain
25	A	128
26	B	32
27	A	64

Which means, setting the gain to 32 should automatically switch to channel B. I don't think it is possible to use channel B with any other gain.

Hope this helps
