fxKeyboard

Use fx-9860 series calculator as a keyboard for computer.

WARNING: THIS TOOL MAY DAMAGE YOUR CALCULATOR OR COMPUTER. ALWAYS FOLLOW THE DOC AND I WILL NOT BE RESPONSIBLE FOR ANY DAMAGE.

Usage

  • Use FA-124 software to copy the Add-in to your calculator.

  • Use the LINK app in calcutor menu to connect the calculator to your computer.

  • READ NOTICE BEFORE THIS STEP! Download Zadig from here. Open Zadig, click Options - List All Device, select CESG502, and replace the original driver with WinUSB.

  • Open the Add-in in your calculator. It will automatically connect to your computer. If you didn't plug the USB cable, it will exit after a short time.

  • Open the fxKeyboardLink software in your computer. Now you can use your calculator as a keyboard for your computer.

  • Some special keyboard mapping:

Notice

  • This tool will automatically open the NumLock in your computer.
  • Once your use Zadig to replace the original driver, you can't use FA-124 to link your calculater. If you want to get back to the original driver, follow Zadig's FAQ here carefully. You need to know that the USB device is CESG502.
  • If you can't connect your calculator to your computer in any way, try to restart your calculator by the button behind.

Known Issue

  • Press the calculator key down continously will not work like that in your computer. The reason is that I only used GetKey function in this Add-in.
  • In cursor mode, the cursor moved slowly in a constant speed.
  • I would be glad if someone can fix the issues above.

Thanks

Thanks Simon Lothar for his great work in syscall.
