Hello Dennis, yes, the DS2438 is a analog input. I made a PCB with all components. Based on this:
[image: picturemessage_io2zuabe.mcz.png] I hope this is working. The Beaglebone detect the "DS18S20Z+" and the "DS2438". And of course I have to calculate the humidity from the anlog input. But the "DS2438" should have a temp sensor and anlog input ... but how I get this info? I use this devicetree: BB-W1-P9.12-00A0.dts /* * Copyright (C) 2015 Robert Nelson <[email protected]> * * Virtual cape for onewire on connector pin P9.12 * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License version 2 as * published by the Free Software Foundation. */ /dts-v1/; /plugin/; #include <dt-bindings/board/am335x-bbw-bbb-base.h> #include <dt-bindings/gpio/gpio.h> #include <dt-bindings/pinctrl/am33xx.h> / { compatible = "ti,beaglebone", "ti,beaglebone-black", "ti,beaglebone-green"; /* identification */ part-number = "BB-W1-P9.12"; version = "00A0"; /* state the resources this cape uses */ exclusive-use = /* the pin header uses */ "P9.12"; fragment@0 { target = <&am33xx_pinmux>; __overlay__ { dallas_w1_pins: pinmux_dallas_w1_pins { pinctrl-single,pins = < BONE_P9_12 0x37 >; }; }; }; fragment@1 { target-path="/"; __overlay__ { onewire { status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&dallas_w1_pins>; compatible = "w1-gpio"; gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>; }; }; }; }; So it is not possible to read the analog value?? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
