Serial Monitor with more features (alternative as example)

I need a Serial Monitor with more features than the standard Serial Monitor in the Arduino IDE. For personal use I made one which can:

  • send and display messages in ascii, hex, decimal format or auto detect
  • also show messages you sent in the message log
  • display ascii, hex and dec representations of all message in the log (on click)
  • auto search and connect to serial device on start and auto reconnect if connection was interrupted
  • store often send messages as convenient buttons to click and send again
  • use a script to automate sending messages depending on received messages.

To see how these features could be implemented see GitHub - NardJ/SerialMonitorPP: A better Arduino Serial Monitor, with a scripting engine to automate send/receive sequences
Below 2 screenshots.

Would be real nice if these features can be implemented in the arduino IDE. (Would save me time maintaining and developing :slight_smile: )

I know this is old, OLD school and is dating myself terribly but it would be nice if the serial monitor also supported escape sequences to position and manipulate the cursor.

I’m thinking the near-universal VT100/VT52 ANSI escape sequences.

For example, this code on an Uno:

#define ESC     0x1B        //27 escape character

uint32_t
    timePrint;
char
    szStr[20];
    
//show some analog channels and GPIO inputs
const uint8_t grADCs[4] = { A0, A1, A2, A3 };
const uint8_t grGPIs[4] = { 2, 3, 4, 5 };
    
void setup() 
{
    Serial.begin( 115200 );
    while( !Serial );

    consoleClearScreen();
    consoleSetCursorVis(false);
    
    for( uint8_t i=0; i<4; i++ )
    {
        consoleSetCursorPosition( 2, 3+i );        
        //ADC Channel 1:
        Serial.print( "ADC Channel " ); Serial.print( i ); Serial.print( ":" );
        
    }//for

    for( uint8_t i=0; i<4; i++ )
    {
        pinMode( grGPIs[i], INPUT_PULLUP );
        consoleSetCursorPosition( 40, 3+i );        
        //GPIO Pin x:
        Serial.print( "GPIO Pin " ); Serial.print( 2+i ); Serial.print( ":" );
        
    }//for
    
}//setup

void loop() 
{
    static uint8_t
        ADCIndex=0;
        
    uint32_t timeNow = millis();
    if( timeNow - timePrint >= 10ul )
    {
        timePrint = timeNow;

        //update the analog channel values
        consoleSetCursorPosition( 17, 3+ADCIndex ); 
        sprintf( szStr, "%4d", analogRead( grADCs[ADCIndex] ) );
        Serial.print( szStr );        

        //update the digital I/O channels
        consoleSetCursorPosition( 52, 3+ADCIndex );        
        Serial.print( digitalRead( grGPIs[ADCIndex] ) ? "HI":"LO" );        

        //bump the channel index
        ADCIndex++;
        if( ADCIndex == 4 )
            ADCIndex = 0;

        //after changing ADC channel, dummy read for sample/hold cct
        analogRead( grADCs[ADCIndex] );
                
    }//if

}//loop

//VT100/VT52 ANSI Escape Sequences
void consoleClearScreen( void )
{
    Serial.write( ESC );
    Serial.print( "[2J" );
    
}//consoleClearScreen

void consoleClearLineFromCursor( void )
{
    Serial.write( ESC );
    Serial.print( "[0K" );
    
}//consoleClearLineFromCursor

void consoleSetCursorVis( bool vis )
{
    char
        szTemp[10];
        
    sprintf( szTemp, "[?25%c", vis==true ? 'h':'l' );
    Serial.write( ESC );
    Serial.print( szTemp );
    
}//consoleSetCursorVis

void consoleSetCursorPosition( uint8_t x, uint8_t y )
{
    char
        szTemp[10];
        
    sprintf( szTemp, "[%d;%dH", y, x );
    Serial.write( ESC );
    Serial.print( szTemp );
    
}//consoleSetCursorPosition

shows this in a Putty terminal:

For reference, the VT100 sequences can be found at http://ascii-table.com/ansi-escape-sequences-vt-100.php

It’d be nice if the IDE’s serial monitor could do this instead of having to invoke a 3rd-party terminal program like Putty.
