Arduino Adafruit ADS1015 library for Mongoose OS

Arduino Adafruit ADS1015 12-BiT/ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier library for Mongoose OS

Tested and works on esp8266/esp32

Description

Analog-to-digital converter or higher-precision ADC.

	precision	samples\sec
ADS1015	12-bit	3300
ADS1115	16-bit	860

The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. See ADS1015 ADS1115 for more information about the hardware.

Features

• Wide supply range: 2.0V to 5.5V
• Low current consumption: Continuous Mode: Only 150uA Single-Shot Mode: Auto Shut-Down
• Programmable data rate: 8SPS to 860SPS
• Internal Low-drift voltage reference
• Internal oscillator
• Internal PGA
• I2C interface: Pin-Selectable Addresses
• Four Single-ended or two differential inputs
• Programmable comparator
• This board/chip uses I2C 7-bit addresses between 0x48-0x4B, selectable with jumpers
