- 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.
