Help text

If you say yes here you get support for AVIA HX711 ADC which is used for weigh cells

This driver uses two GPIOs, one acts as the clock and controls the channel selection and gain, the other one is used for the measurement data

Currently the raw value is read from the chip and delivered. To get an actual weight one needs to subtract the zero offset and multiply by a scale factor. This should be done in userspace.

This driver can also be built as a module. If so, the module will be called hx711.
