Texas Instruments AFE4403 Heart rate and Pulse Oximeter
Required properties:
- compatible : Should be "ti,afe4403".
- reg : SPI chip select address of device.
- tx-supply : Regulator supply to transmitting LEDs.
- interrupts : The interrupt line the device ADC_RDY pin is
connected to. For details refer to,
../../interrupt-controller/interrupts.txt.
Optional properties:
- reset-gpios : GPIO used to reset the device.
For details refer to, ../../gpio/gpio.txt.
For other required and optional properties of SPI slave nodes
please refer to ../../spi/spi-bus.txt.
Example:
&spi0 {
heart_mon@0 {
compatible = "ti,afe4403";
reg = <0>;
spi-max-frequency = <10000000>;
tx-supply = <&vbat>;
interrupt-parent = <&gpio1>;
interrupts = <28 IRQ_TYPE_EDGE_RISING>;
reset-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
};
};
