* AVIA HX711 ADC chip for weight cells
|
|
Bit-banging driver
|
|
|
|
Required properties:
|
|
- compatible: Should be "avia,hx711"
|
|
- sck-gpios: Definition of the GPIO for the clock
|
|
- dout-gpios: Definition of the GPIO for data-out
|
|
See Documentation/devicetree/bindings/gpio/gpio.txt
|
|
- avdd-supply: Definition of the regulator used as analog supply
|
|
|
|
Optional properties:
|
|
- clock-frequency: Frequency of PD_SCK in Hz
|
|
Minimum value allowed is 10 kHz because of maximum
|
|
high time of 50 microseconds.
|
|
|
|
Example:
|
|
weight {
|
|
compatible = "avia,hx711";
|
|
sck-gpios = <&gpio3 10 GPIO_ACTIVE_HIGH>;
|
|
dout-gpios = <&gpio0 7 GPIO_ACTIVE_HIGH>;
|
|
avdd-suppy = <&avdd>;
|
|
clock-frequency = <100000>;
|
|
};
