Ensure to comply to the [Oracle JDK Licence agreement](https://www.oracle.com/downloads/licenses/oracle-javase-license.html).\r\n* Developed for personal use only.\r\n\r\n## Functionality\r\n* Design LCD display layouts for 20x4 (20 columns, 4 rows) or 16x2 displays (16 columns, 2 rows).\r\n* Save / open the display layout to / from a textfile located in the application folder.\r\n* Generate simple B4R or C++ code.\r\n* Example B4R program included.\r\n\r\n## Dependency\r\nThe following libraries are used which are included in the archive _lcddisplaydesigner.zip_, folder libraries.\r\n* For B4R programms, the B4R library rLiquidCrystal_I2C \r\n* For Arduino C++ sketches, the library LiquidCrystal_I2C\r\n\r\n[B4R](https://www.b4x.com/b4r.html) development tool for native Arduino and ESP programs by [Anywhere Software](https://www.b4x.com).\r\n\r\n## Files\r\n* lcddisplaydesigner.zip - B4J application source.\r\n* lcddisplaydesigner.jar - Java archive (see install on how to run).\r\n* rLiquidCrystal_I2C.zip - B4R / C++ library to write to LCD displays LCD2004 or LCD1602.\r\n* liquidcrystali2c.b4r - B4R Example writing to the LCD Display LCD2004.\r\n* run8.bar, run11.bat - Windows batch file to run the Java archive lcddisplaydesigner.jar.\r\n* hello_world.lcd - Sample LCD display layout.\r\n\r\n## Install\r\nUnpack the ZIP archive to a folder of choice.\r\n\r\nRun the Java jar **lcddisplaydesigner.jar**\r\nExample running with Java 8:\r\n```\r\njava -jar lcddisplaydesigner.jar\r\n```\r\n\r\n**Notes:**\r\n* The full B4J source code is included.\r\n* An example batch file \"run8.bat\" to run under Windows is included. Ensure to set the path to the JDK8 folder.\r\n* There is also a \"run11.bat\" for running with openJDK11 - might require to recompile first with B4J using openJDK11.\r\n\r\n## Licence\r\nThis program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by \r\nthe Free Software Foundation, either version 3 of the License, or (at your option) any later version.\r\nThis program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of\r\nMERCHANTABILITY or FITNESS for A PARTICULAR PURPOSE.
