HX71708 v0.1.0 (alpha)

Overview

The HX71708 library is a fork of https://github.com/RobTillaart/HX711 version 0.5.2. It is built for the HX71708 from Avia Semiconductor (Xiamen) Ltd. using the Arduino IDE.

Whereas the HX711 uses clock pulses to set gain, the HX71708 operates with a fixed gain, and uses clock pulses to set the data sample rate of 10, 20, 80, or 320 Hz. This is the only modification I have made to the code base.

set_data_rate() Behavior

Version	Description	Behavior
set_data_rate(rate)	Sets data rate if it differs from the current setting	Skips reapplying if the rate is already active. Returns true if valid, false otherwise
set_data_rate(rate, false)	Same as above — explicitly avoids reapplying the same rate	Returns true if the rate is unchanged or successfully applied
set_data_rate(rate, true)	Forces the rate to be applied even if it’s the same	Re-applies rate and calls read() to resync
set_data_rate(invalid_rate)	Tries to set an unsupported SPS value	Returns false, makes no change
bool ok = set_data_rate(...)	You can capture the return value to verify success	true for valid/accepted rate, false for invalid input

Permitted Data Rates

The following constants are valid arguments for scale.set_data_rate():

Constant Name	SPS Value	Example Code
HX71708_DATA_RATE_10	10 SPS	scale.set_data_rate(HX71708_DATA_RATE_10);
HX71708_DATA_RATE_20	20 SPS	scale.set_data_rate(HX71708_DATA_RATE_20);
HX71708_DATA_RATE_80	80 SPS	scale.set_data_rate(HX71708_DATA_RATE_80);
HX71708_DATA_RATE_320	320 SPS	scale.set_data_rate(HX71708_DATA_RATE_320);
