Can you read the message on the LCD in this photo?  Happy Birthday, Small Basic!

Today's Small Basic program is

' Send Text to Serial Port

' Version 0.1

' Copyright © 2016 Nonki Takahashi. The MIT License.

 

TextWindow``.`` Title `` = ``"Send Text to Serial Port"

Init``(``)

While ``"True"

  `` txt `` = ``TextWindow``.``Read``(``)

  ``LDCommPort``.``TXString``(`` txt `` + ``LF``)

EndWhile

 

Sub ``Init

  `` LF `` = ``Text``.``GetCharacter``(``10``)

  `` status `` = ``LDCommPort``.``OpenPort``(``"COM3"``,``9600``)

  ``LDCommPort``.``SetEncoding``(``"Ascii"``)

EndSub

And the Arduino sketch is

 // LCD control via I2C from serial port

#include <Wire.h> 
#include <LiquidCrystal_I2C.h>

// Variable definition
const int r = 2;                      // rows
const int c = 16;                     // columns
LiquidCrystal_I2C lcd(0x3F, c, r); // set the LCD address to 0x3F
String inputString = "";              // received string
boolean stringComplete = false;       // received?

void setup()
{
  lcd.init();                         // initialize the lcd 
  lcd.backlight();
  Serial.begin(9600);
}

void loop() {
  if (stringComplete) {
    int len = inputString.length();
    lcd.clear();
    if (len <= c) {
      lcd_print(inputString);
    } else {
      lcd_print(inputString.substring(0, c));
      lcd.setCursor(0, 1);
      lcd_print(inputString.substring(c));
    }
    inputString = "";
    stringComplete = false;
  }
}

// Print string to LCD
void lcd_print(String str) {
  int len = str.length();
  for (int i = 0; i < len; i++) {
    lcd.print(str.charAt(i)); 
  }
}

// Serial event handler
void serialEvent() {
  while (Serial.available()) {
    char inChar = (char)Serial.read();  // read 1 byte
    if (inChar == '\n') {
      // flag on if reseived newline
      stringComplete = true;
    } else {
      inputString += inChar;  // append it to the string
    }
  }
}

    I so want to see the next version of Small Basic, v1.3 i guess. I'm looking forward to try it !!I am certain that they will be several new functions, commands, instructions which will be added to the base engine. Congratulations Microsoft for this great free software that makes us return to our passions of amateur programmers. !Here is according to (wiki) the version history:2008-10-23 V0.1 released 2008-12-17 V0.2 released 2009-02-10 V0.3 released 2009-04-14 V0.4 released 2009-06-16 V0.5 released 2009-08-19 V0.6 released 2009-10-23 V0.7 released 2010-02-04 V0.8 released 2010-06-11 V0.9 released 2010-11-17 V0.91 released 2011-02-08 V0.95 released2011-07-12 V1.0 released2015-03-27 V1.1 released2015-10-01 V1.2 released

        my wishlist to Santa Claus for SB V1.3 :))Sound.playmusic ( lenght of notes 1 to 64 to 1 to 128)Sound.playmusic ( possibilities to play 4 notes in the same time , to program chords )an simple alternative graphicswindow command to textwindow.read(), like graphicswindow.read() , to enter keyboard data intercative.a no border graphicswindow ( full screen)a way for MATH to handle bigger number like 10 power 75 , ex: ( Sun mass 10^30 multiply by Earth mass 10^24 ) = 10^54 , gravitational law computing.and finally and finally, to improve the speed of the setpixel command.

          setpixel speedup is already done in ld xtension by LDImage.GetWorkingImagePixel and LDImage.SetWorkingImagePixel also can be done by 2d matrix LDImage.GetImagePixels and LDImage.SetImagePixels

            u should use the ms paint.net app then, which uses c# language and scripts to control each pixel very fast

            I got some push back from our community council and teachers about adding more into the core library that's currently available as extensions. We'll get some new data in the future and see if we want to make that request again. But one solution is the Extension Manager, which makes it easier to find, install, and turn on/off extensions.
