P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the Maxim LM75 Digital Temperature Sensor

lm75-spin

---

This is a P8X32A/Propeller driver object for the Maxim LM75 Digital Temperature Sensor and Thermal Watchdog (I2C).

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 ~30kHz (P1: SPIN I2C), up to 400kHz (P1: PASM I2C, P2)
• Read die temperature
• Set overtemperature (assert) and hysteresis (clear) interrupts
• Set interrupt active high/low, comparator or interrupt mode
• Alternate I2C addresses

Requirements

P1/SPIN1:

• spin-standard-library
• 1 extra core/cog for the PASM I2C engine (none if the SPIN I2C engine is used)
• sensor.temp_rh.common.spinh (source: spin-standard-library)

P2/SPIN2:

• p2-spin-standard-library
• sensor.temp_rh.common.spin2h (source: p2-spin-standard-library)

Compiler Compatibility
