ADS1015 (I2C)



This device is a 12-bit A-D converter with 4 inputs.



The inputs can be used single ended or in certain differential combinations.



For configuration all possible combinations are mapped to 8 channels:

  0: Voltage over AIN0 and AIN1.

  1: Voltage over AIN0 and AIN3.

  2: Voltage over AIN1 and AIN3.

  3: Voltage over AIN2 and AIN3.

  4: Voltage over AIN0 and GND.

  5: Voltage over AIN1 and GND.

  6: Voltage over AIN2 and GND.

  7: Voltage over AIN3 and GND.



Each channel can be configured individually:

 - pga is the programmable gain amplifier (values are full scale)

    0: +/- 6.144 V

    1: +/- 4.096 V

    2: +/- 2.048 V (default)

    3: +/- 1.024 V

    4: +/- 0.512 V

    5: +/- 0.256 V

 - data_rate in samples per second

    0: 128

    1: 250

    2: 490

    3: 920

    4: 1600 (default)

    5: 2400

    6: 3300



1) The /ads1015 node



  Required properties:



   - compatible : must be "ti,ads1015"

   - reg : I2C bus address of the device

   - #address-cells : must be <1>

   - #size-cells : must be <0>



  The node contains child nodes for each channel that the platform uses.



  Example ADS1015 node:



    ads1015@49 {

	    compatible = "ti,ads1015";

	    reg = <0x49>;

	    #address-cells = <1>;

	    #size-cells = <0>;



	    [ child node definitions... ]

    }



2) channel nodes



  Required properties:



   - reg : the channel number



  Optional properties:



   - ti,gain : the programmable gain amplifier setting

   - ti,datarate : the converter data rate



  Example ADS1015 channel node:



    channel@4 {

	    reg = <4>;

	    ti,gain = <3>;

	    ti,datarate = <5>;

    };

Kernel driver ads1015

=====================



Supported chips:

  * Texas Instruments ADS1015

    Prefix: 'ads1015'

    Datasheet: Publicly available at the Texas Instruments website :

               http://focus.ti.com/lit/ds/symlink/ads1015.pdf

Description

-----------



This driver implements support for the Texas Instruments ADS1015.



This device is a 12-bit A-D converter with 4 inputs.



The inputs can be used single ended or in certain differential combinations.



The inputs can be made available by 8 sysfs input files in0_input - in7_input:

in0: Voltage over AIN0 and AIN1.

in1: Voltage over AIN0 and AIN3.

in2: Voltage over AIN1 and AIN3.

in3: Voltage over AIN2 and AIN3.

in4: Voltage over AIN0 and GND.

in5: Voltage over AIN1 and GND.

in6: Voltage over AIN2 and GND.

in7: Voltage over AIN3 and GND.



Which inputs are available can be configured using platform data or devicetree.



By default all inputs are exported.



Platform Data

-------------



In linux/i2c/ads1015.h platform data is defined, channel_data contains

configuration data for the used input combinations:

- pga is the programmable gain amplifier (values are full scale)

  0: +/- 6.144 V

  1: +/- 4.096 V

  2: +/- 2.048 V

  3: +/- 1.024 V

  4: +/- 0.512 V

  5: +/- 0.256 V

- data_rate in samples per second

  0: 128

  1: 250

  2: 490

  3: 920

  4: 1600

  5: 2400

  6: 3300



Example:

struct ads1015_platform_data data = {

	.channel_data = {

		[2] = { .enabled = true, .pga = 1, .data_rate = 0 },

		[4] = { .enabled = true, .pga = 4, .data_rate = 5 },

	}

};



In this case only in2_input (FS +/- 4.096 V, 128 SPS) and in4_input

(FS +/- 0.512 V, 2400 SPS) would be created.



Devicetree

----------



Configuration is also possible via devicetree:

Description

-----------



SMSC SCH5627 Super I/O chips include complete hardware monitoring

capabilities. They can monitor up to 5 voltages, 4 fans and 8 temperatures.



The hardware monitoring part of the SMSC SCH5627 is accessed by talking

through an embedded microcontroller. An application note describing the

protocol for communicating with the microcontroller is available upon

request. Please mail me if you want a copy.

Pin mapping

-----------



Here is a summary of the pin mapping for the W83795G and W83795ADG.

This can be useful to convert data provided by board manufacturers

into working libsensors configuration statements.
