RACM600_I2C

An Arduino library for interfacing with the RECOM RACM600-SL power supply over I2C/PMBus. This library simplifies communication with the RACM600, handling voltage, current, and temperature monitoring, as well as fault detection and power control.

About This Project

This library was developed to facilitate I2C communication with the RACM600-SL power supply, allowing users to monitor and control power parameters using standard PMBus commands. It provides functions for reading input/output voltage, current, temperature, and fault status, as well as enabling/disabling power output.

Marine Applied Research & Exploration (MARE) develops and shares this code to support the exploration and documentation of deep-water ecosystems, contributing to their conservation and management. To sustain our mission and initiatives, please consider donating at https://maregroup.org/donate.

Installation

To install this library:

1. Download the latest release from the Releases page.

2. Extract the folder and place it inside your Arduino libraries directory (Documents/Arduino/libraries/).

3. Open Arduino IDE and include the library in your sketch:

   #include "RACM600.h"

Usage

A basic example of using the RACM600-SL power supply:

#include <Wire.h>
#include "RACM600.h"

RACM600 psu;

void setup() {
    Serial.begin(9600);
    Wire.begin();
    psu.begin();

    Serial.println("Checking power supply status...");

    psu.enableOutput();
    delay(500);
    Serial.println("Power Output Enabled");

    Serial.println("Checking faults...");
    psu.readFaults();
}

void loop() {
    // Read and display power parameters
    Serial.print("Voltage: "); Serial.print(psu.readVoltage()); Serial.println(" V");
    Serial.print("Current: "); Serial.print(psu.readCurrent()); Serial.println(" A");
    Serial.print("Temperature: "); Serial.print(psu.readTemperature()); Serial.println(" °C");

    // Check for any new faults
    psu.readFaults();

    delay(5000);
}
