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
|
||||
|
||||
Authors:
|
||||
Dirk Eibach, Guntermann & Drunck GmbH <eibach@gdsys.de>
|
||||
|
||||
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:

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.

This driver provides support for the LIS3* accelerometers, such as the

LIS3LV02DL or the LIS331DL. In particular, it can be found in a number
|
||||
of HP laptops, which have the "Mobile Data Protection System 3D" or
|
||||
"3D DriveGuard" feature. On such systems the driver should load
|
||||
automatically (via ACPI alias). The accelerometer might also be found
|
||||
in other systems, connected via SPI or I2C. The accelerometer data is
|
||||
readable via /sys/devices/platform/lis3lv02d.
|
||||
|
||||
This driver also provides an absolute input class device, allowing
|
||||
a laptop to act as a pinball machine-esque joystick. It provides also
|
||||
a misc device which can be used to detect free-fall. On HP laptops,
|
||||
if the led infrastructure is activated, support for a led indicating
|
||||
disk protection will be provided as hp::hddprotect. For more
|
||||
information on the feature, refer to Documentation/hwmon/lis3lv02d.
|
||||
|
||||
This driver can also be built as modules. If so, the core module
|

will be called lis3lv02d and a specific module for HP laptops will be
