Summary of 8051 PS2 KEYBOARD WITH LCD WRITING TEXT
This article describes an 8051 microcontroller project that uses a PS/2 keyboard to input text and display it on an LCD. The system converts keystrokes into ASCII codes via scan codes, which the microcontroller processes to update the screen. The design utilizes specific header files for LCD driving and keyboard scanning, with code examples provided in Keil and simulation files available for Proteus ISIS Ares.
