ads1x15

CircuitPython base class driver for ADS1015/1115 ADCs.

class adafruit_ads1x15.ads1x15.ADS1x15(i2c: busio.I2C, gain: float = 1, data_rate: Optional[int] = None, mode: adafruit_ads1x15.ads1x15.Mode = 256, address: int = 72)[source]

Base functionality for ADS1x15 analog to digital converters.

property data_rate

The data rate for ADC conversion in samples per second.

property gain

The ADC gain.

property gains

Possible gain settings.

get_last_result(fast: bool = False) → int[source]

Read the last conversion result when in continuous conversion mode. Will return a signed integer value. If fast is True, the register pointer is not updated as part of the read. This reduces I2C traffic and increases possible read rate.

property mode

The ADC conversion mode.

property rate_config

Rate configuration masks.

property rates

Possible data rate settings.

read(pin: microcontroller.Pin, is_differential: bool = False) → int[source]

I2C Interface for ADS1x15-based ADCs reads.

params:
param pin

individual or differential pin.

param bool is_differential

single-ended or differential read.

class adafruit_ads1x15.ads1x15.Mode[source]

An enum-like class representing possible ADC operating modes.
