-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
-
- * Texas Instruments ADS1115
-
- Prefix: 'ads1115'
-
- Datasheet: Publicly available at the Texas Instruments website:
-
- http://focus.ti.com/lit/ds/symlink/ads1115.pdf
-
-Authors:
- Dirk Eibach, Guntermann & Drunck GmbH <eibach@gdsys.de>
-
-Description
------------
-
-This driver implements support for the Texas Instruments ADS1015/ADS1115.
-
-This device is a 12/16-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/platform_data/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:
