We designed a double keyboard acquisition module with brightness adjustment and brightness memory functions for a certain type of display and control terminal.The module synthesized PWM output and EEPROM memory function to integrate double keyboard acquisition and display brightness control into one module.Through the virtual PS/2 keyboard and CPU keyboard controller,we could achieve three goals:first,to respond two types of input keyboard through one PS/2 keyboard interface at the same time;second,to allow for plug and play of the PS/2 keyboard under the WINDOWS system;third,independent screen brightness control and brightness memory function.
