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.
- 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)
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)
| Processor | Language | Compiler | Backend | Status |
|---|---|---|---|---|
| P1 | SPIN1 | FlexSpin (6.9.4) | Bytecode | OK |
| P1 | SPIN1 | FlexSpin (6.9.4) | Native/PASM | OK |
| P2 | SPIN2 | FlexSpin (6.9.4) | NuCode | Untested |
| P2 | SPIN2 | FlexSpin (6.9.4) | Native/PASM2 | OK |
(other versions or toolchains not listed are not supported, and may or may not work)
- Tested with ADS1115
- Doesn't support the high-speed (3.4MHz) I2C mode
- Models other than ADS1115 untested
