ads1115-spin

---

This is a P8X32A/Propeller driver object for the TI ADS1115 ADC

IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.

Salient Features

• I2C connection at up to 400kHz
• Alternate I2C addresses supported
• Read in continuous or single-shot measurement modes
• Measurement ready flag for single-shot mode
• Set full-scale range and sampling rate
• Read data as ADC words or microvolts
• Read current or previous measurement
• Set interrupt (low, high) thresholds, persistence
• Set measurement channel (single-ended mode) or measurement pair (differential mode)

Requirements

P1/SPIN1:

• 1 extra core/cog for the PASM I2C engine (none if bytecode engine is used)
• signal.adc.common.spinh (provided by spin-standard-library)

P2/SPIN2:

• p2-spin-standard-library
• signal.adc.common.spin2h (provided by p2-spin-standard-library)

Compiler Compatibility

Processor	Language	Compiler	Backend	Status
