MatoiDev/Sentinel-Logger

Sentinel Logger (for Nextion displays)

Allows you to use your Nextion display as a serial terminal-style monitor

Features

• Using HardwareSerial for logging (for Arduino Mega/Due, etc.)
• Using SoftwareSerial for logging (for Arduino Uno/Nano/Mini, etc.)
• Using both at the same time.
• Scroll effect (When overloaded, the page is not cleared, but scrolls down 1 line)

How to use

1. Add Logger.h and Logger.cpp to your project

2. Download Sentinel[v1.0].tft to your display

All Done!

Examples

• Software serial

#include "Logger.h"
#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3);
Logger softwareLogger(mySerial); // 1. Initialize logger

void setup() {
    ...
    softwareLogger.begin(9600); // 2. Begin serial
    ...
}

void loop() {
    ...
    if (Serial.available()) {
        String command = Serial.readStringUntil("\n");
        softwareLogger.log(command); // 3. Log
    }
    ...
}

• Hardware serial

#include "Logger.h"

Logger hardwareLogger(Serial2); // 1. Initialize logger

void setup() {
    ...
    hardwareLogger.begin(9600); // 2. Begin serial
    ...
}

void loop() {
    ...
    if (Serial.available()) {
        String command = Serial.readStringUntil("\n");
        hardwareLogger.log(command); // 3. Log
    }
    ...
}

Commands

There is nothing easier than using them.

/* Somewhere in your code: */
...
myLogger.log("<command>")
...

There are 2 basic commands:

• clear - erase all logs in your session, it doesn't create a new session

• page <PageID> - go to a specific page:

  • Logger - Terminal Page, creates a new session
  • Main - Lobby, closes an existing session

Skipping Lobby

If you don't have to wait for your board to connect, you can skip this screen, just call skipLobby() in your setup():

void setup() {
    ...
    myLogger.skipLoading();
    ...
}

Project support

I don't have much knowledge in this area, it's just my solution to this problem and it's far from ideal. I believe that you have much more knowledge than I do if you came here, so if you liked the project and you know how it can be improved, then feel free to make your pull request!
