gabbapeople/hx711@0.0.3
A library to interface HX711 24-Bit Analog-to-Digital Converter (ADC) for reading load cells / weight scales.
| Node | Description |
|---|---|
| hx711-device | The main device node for the HX711 modules.
|
| tare | Sets the OFFSET value for tare weight; |
| set-scale | Sets the SCALE value.
This value is used to convert the raw data to "human readable" measure units.
1.0 by default. |
| amperka-weight-sensor | Drives the Weight sensor based on the HX711 24-Bit Analog-to-Digital Converter (ADC) by Amperka. |
| example-calibrate-scale | The example patch to obtain the SCL (scale) value.
1. Prepare the weight of the known mass. And bind its weight in grams to the constant weight node.
2. Flash the patch in the Debug mode.
3. After loading the patch you have about 20 seconds to put the prepaired weight on scales.
4. Wait for the Scale value. |
| read-average | Reads an average raw value from the HX711 device. |
| get-value | Reads the (average raw value from the sensor - OFFSET). That is the current value without the tare weight. |
| get-weight | Reads the current weight in "human readable" measure units. The uints depend on the SCALE value.
This is the average raw value without the tare weight and divided by the SCALE value obtained via calibration.

| example-scale | No description |
| amperka-scale | Quickstart node for the scale based on Weight Sensor by Amperka. |
