ESP32 Custom Brownout Handler Library

This library provides a way to integrate a custom brownout handler function for ESP32 devices, enhancing system stability during voltage dips. It's compatible with both the ESP-IDF and Arduino development frameworks.

Features

• Customizable Brownout Handling: Tailor the response to brownout conditions with your own function.
• Optimized for Real-Time Execution: Use the IRAM_ATTR to ensure the handler is in IRAM for quick execution.
• Framework Compatibility: Works with both ESP-IDF and Arduino setups.

How to Install

For ESP-IDF, clone this repository into your components directory. For Arduino, include the library in your project's libraries directory.

How to Use

Before you use the library, ensure you have included the esp_attr.h header to enable the use of IRAM_ATTR.

Here's how to set up your custom brownout handler:

With ESP-IDF:

#include "esp_attr.h"
#include "ESP32_Custom_Brownout_Handler.h"

// Define your custom brownout handler function with IRAM_ATTR
void IRAM_ATTR custom_brownout_handler() {
    // Custom logic for handling brownout conditions
}

void app_main() {
    // Initialize the custom brownout handler
    ESP32_Custom_Brownout_Fn(custom_brownout_handler);
    // Rest of your setup code
}

With Arduino:

#include "esp_attr.h"
#include "ESP32_Custom_Brownout_Handler.h"

// Global instance of the custom brownout handler
void IRAM_ATTR custom_brownout_handler() {
    // Custom logic for handling brownout conditions
}

// Initialize with your custom handler
ESP32_Custom_Brownout_Fn customBrownoutHandler(custom_brownout_handler);

void setup() {
    // Your setup code here
}

void loop() {
    // Main code loop
}

Global Instance:

You may also declare the handler globally if you prefer:

#include "esp_attr.h"
#include "ESP32_Custom_Brownout_Handler.h"

// Global instance of the custom brownout handler
void IRAM_ATTR custom_brownout_handler() {
    // Custom logic for handling brownout conditions
}

// Initialize with your custom handler
ESP32_Custom_Brownout_Fn customBrownoutHandler(custom_brownout_handler);

void setup() {
    // Your setup code here
}

void loop() {
    // Main code loop
}

Remember that the function you pass to ESP32_Custom_Brownout_Fn must be marked with IRAM_ATTR to ensure that it's placed in IRAM for faster execution which is critical during brownout conditions.
