ADS1015 / ADS1115 Raspberry Pi Analog to Digital
Next you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install these libraries from Adafruit's CircuitPython library bundle. For example the Circuit Playground Express guide has a great page on how to install the library bundle for both express and non-express boards.
In this example we connect an ADS1115 analog-to-digital converters to a Raspberry Pi. Lets look at the ADS1115. The ADS1115 is a precision, low-power, 16-bit, I 2 C-compatible, analog-to-digital converters (ADCs) offered in an ultra-small, leadless, X2QFN-10 package, and a VSSOP-10 package. The ADS1115 incorporates a low-drift voltage reference and an oscillator
First wire up the ADC to your board exactly as shown on the previous pages for Arduino using an I2C interface. Here's an example of wiring a Feather M0 to the ADS1115 with I2C:
The ADS1115 also incorporate a programmable gain amplifier (PGA) and a digital comparator. These features, along with a wide operating supply range, make the ADS1115 well suited for power- and space-constrained, sensor measurement applications.
ADS1115 4-Channel ADC Uses I2C with Raspberry Pi. by Lewis Loflin. The ADS1115 is a 4-channel analog-to-digital converter utilizes the I2C proto call with selectable addresses. Here we look at connecting this device with the Raspberry Pi running the Debian based Raspbian operating system. The reality is we are using a Linux system Save it and reboot your raspberry Pi. Python code to use the ADS1015 and ADS1115 analog to digital converters with a Raspberry Pi or BeagleBone black. To install the library from source (recommended) run the following commands on a Raspberry Pi or other Debian-based OS system print(chan.value, chan.voltage) print(chan.value, chan.voltage) Gain Both the ADS1015 and the ADS1115 have a Programmable Gain (PGA) that you can set to amplify the incoming signal before it reaches the ADC. The available settings and associated Full Scale (FS) voltage range are shown in Table 3 of the datasheet.The ADS1115 performs conversions at data rates up to 860 samples per second (SPS). The PGA offers input ranges from ±256 mV to ±6.144 V, allowing precise large- and small-signal measurements. The ADS1115 features an input multiplexer (MUX) that allows two differential or four single-ended input measurements. Use the digital comparator in the ADS1115 for under- and overvoltage detection.
A guide to the ADS1115 and ADS1015 analog converters. Next you'll need to install the Adafruit CircuitPython ADS1x15 library on your CircuitPython board. First make sure you are running the latest version of Adafruit CircuitPython for your board. Next you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install these libraries from Adafruit. Overview The Raspberry Pi is an excellent small board computer that you can use to control digital inputs & outputs. However what do you do when you want to read an analog signal, like what you might get from a thermistor, potentiometer, o The ADS1115 operates in either continuous-conversion mode or single-shot mode. The devices are automatically powered down after one conversion in single-shot mode; therefore, power consumption is significantly reduced during idle periods.ads.gain = 16 ads.gain = 16 Note that setting gain will affect the raw ADC value but not the voltage (expect for variance due to noise). For example:

al application, such as PuTTY.. The other two serial interfaces are the Serial Peripheral Interface (SPI) and Inter-Integrated-Circuit bus (I2C)
If your default Python is version 3 you may need to run 'pip' instead. Just make sure you aren't trying to use CircuitPython on Python 2.x, it isn't supported!
>>> ads.gain 1 >>> chan.value, chan.voltage (84, 0.168082) >>> ads.gain = 16 >>> ads.gain 16 >>> chan.value, chan.voltage (1335, 0.167081) >>> >>> ads.gain 1 >>> chan.value, chan.voltage (84, 0.168082) >>> ads.gain = 16 >>> ads.gain 16 >>> chan.value, chan.voltage (1335, 0.167081) >>> The value changed from 84 to 1335, which is pretty close to 84 x 16 = 1344. However, the voltage returned in both cases is still the actual input voltage of ~0.168 V.

ADS1115 16-bit ADC I2c Windows IoT C#. I've used the DMAP driver on the Raspberry Pi, but I suppose it would run with the default inbox driver, too. To make sure you won't damage your IC, read the documentation. For example, the analog input must be between GND - 0.3V and VDD + 0.3V and it's recommended to clamp the signal with external.
