@ -24,14 +32,15 @@ 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.
- 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.

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 = {
- 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

- 1: 250
- 2: 490
- 3: 920

- 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.
