Why you should use Logisim ITA

• No retro-compatibility problems with old .circ files
• A lot of new components and small changes
• Bug fixes and optimizations
• Constantly supported and listening to all your suggestions/reports

Changelog

• Core Stuff:
  • Italian, Simplified Chinese and partial french translation!
  • Autoupdates!
  • Compiled with Java 14
  • Complete new movement system with mouse dragging
  • Auto center and Auto zoom when opening new files/circuits or with ctrl-0, double mouse wheel click and with the round button you’ll see on the lower-right corner
  • Almost infinite canvas, arrows will show you in what direction is the circuit if it’s outside of your view
  • Zoom in and out using mouse wheel where you’re pointing at
  • Double click with Edit Tool to label components
  • Load libraries from folder at startup (Preferences / Fork)
  • Selectable painting refresh rate, default 60Hz (Legacy was 20Hz and sometimes lagging)
  • Anti Aliasing, Look and Feel and Fill Component’s Background preference
  • Clock custom frequency
  • Press ESC or DEL to cancel “Add Tool” action, F1 opens Library Reference
  • Increased output limit in Analyze Circuit to 32
  • Analyze Circuit should calculate table/expression with any kind of component
  • Added “Clear Log” button
  • Added missing tooltips
  • Changed some default values
• New components:
  • Wiring->Programmable Generator
  • TTL gates (7400, 7402, 7404, 7408, 7432, 7447, 7485, 7486, 74165, 74283, 747266)
  • I/O->Digital Oscilloscope
  • I/O->Switch
  • I/O->Dip Switch
  • I/O->Slider
  • I/O->RGB LED
  • I/O->Buzzer
  • Memory->PLA ROM
  • Plexers->7-Segment Display Decoder
• Component changes:
  • New FF layout
  • The Shift Register will show you its internal bits even when set to serial load
  • Right click on Pin, Edit Contents and set its value typing the decimal number
  • Added Sel pin in Register
  • Added Preset pin in Register and Counter
  • TTY and Keyboard components can use 16-bit values (UTF-16)
• New Attributes:
  • Controlled Buffer / Inverter: Negate Control Input attribute
  • Added Sel Active Level attribute in components with Sel pin
  • Priority Plexer “No Input” attribute
  • Joystick “Facing” attribute
  • Bit Selector “Select location” attribute
  • Added Label Color attribute for each component with Label attribute and Text Tool
  • Added Label for RAM, ROM and PLA ROM
  • FF D, S-R: “Latch” option in Trigger attribute
  • New Counter behavior (different pin logic)
• Fixed bugs:
  • Big fixes to Log menu and Log output file
  • Big fixes for Text Tool
  • Fixed empty template bug introduced in Logisim 2.7.0
  • Fixed input positions in wide gates with 4 inputs
  • Fixed opening new file in new window with old window not used
  • Fixed bugged 32b multiplier
  • Some fix from original early version 2.7.2.255

Bugs

• All the original Logisim’s bugs we haven’t fixed yet:
  • Some random blue/red line caused by bad values refresh
  • Some problem with high frequencies
  • String attribute not calling attributechanged method while writing its value
• Programmable Generator: trying to edit its values by clicking on “(click to edit)” is a bit buggy, use “Edit Contents” instead in menu by clicking with right mouse button

Features we want to add

• Solve dirty points when rotating
• Add a new type of library
• Draw also in circuits
• Suggest us everything at [email protected]

Retro-compatibility

Due to a bug in the original Logisim, wide gates with 4 inputs had a bad pin positioning. I fixed this problem but if you open an old file containing gates with those attributes, its inputs will be disconnected and a warning message will appear

How to compile & use

The project uses maven, from Logisim/Logisim-Fork run mvn package or use your ide and import the directory as a maven project, the output file is target/Logisim-jar-with-dependencies.jar

Translation

New strings are translated really bad (Google Translate) because i just know Italian and English.
You can help me translating other languages or adding a new one, if you want so, contact me at [email protected]
