Universal Debug Library

A universal debug class for Arduino (Uno/Nano) and ESP32 boards that supports both standard Serial.print() calls and printf-style formatting to simultaneous outputs (Hardware Serial Monitor and Bluetooth Serial).

Features

• Dual Output: Sends data to Hardware Serial and Bluetooth Serial simultaneously.
• Platform Agnostic: Automatically uses SoftwareSerial (Uno/Nano) or BluetoothSerial (ESP32).
• Memory Efficient: Inherits from Arduino's Print class and uses stack memory buffers for formatting.
• Configurable: Use #define flags to enable/disable Bluetooth output or force platform detection.

Usage Example (ESP32)

#define FORCE_ESP32 1
#define DEBUG_BLUETOOTH_ENABLED 1
#include <UniversalDebug.h>

UniversalDebug Debug(Serial);

void setup() {
    Debug.begin(115200, "MyESP32Device");
    Debug.println("System Booted.");
    Debug.printf("Voltage is %.2fV\n", 3.3);
}

void loop() {
    Debug.println("Heartbeat...");
    delay(2000);
}
