Summary of 8051 PS2 KEYBOARD WITH LCD WRITING TEXT
This project demonstrates an 8051 microcontroller system that captures text input via a PS/2 keyboard and displays it on an LCD. The system utilizes ASCII codes generated from keystrokes to drive the display. It involves specific header files for LCD driving and scan code mapping, with source code available for Keil and Proteus simulation environments.
