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.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
|
||
|
|
- exported-channels : exported_channels is a bitmask that specifies which
|
||
|
|
channels should be accessable by the user.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
ads1015@49 {
|
||
|
|
compatible = "ti,ads1015";
|
||
|
|
reg = <0x49>;
|
||
|
|
exported-channels = <0x14>;
|
||
|
|
};
|
||
|
|
|
||
|
|
In this example only channel 2 and 4 would be accessable by the user.
