issue reading A0 on display shield if HX711 loaded about hx711

[bogde]

i'm really sorry but due to the lack of time i can't provide any kind of support for this project anymore. also, i haven't used the chip in months and don't plan to use it soon either, i don't have an arduino uno, nor the type of display you're using. you should find a better supported library, or try to write your own. you could also try to re-route the analog input pin from your display shield, or at least use a1, a2 for the hx711 instead of a1,a3. again, i'm sorry i can't help you out. good luck.

@mkocan This library should have no impact on other pins.
Maybe you actually have an electrical short between A0 and A1?

When the libaray is not initialised, A1 would be a high-impedance input and not affect readings of A0. But as soon as the library is initialised, A1 gets configured as an output to drive SCK, and that would force A1 (and in turn A0) to be LOW after each read of the scale.
