E1115F PS/2 Keyboard to ASCII Converter
The E1115F PS/2 to ASCII Converter decodes the complex PS/2 keyboard protocol into a single ASCII byte on the make of a keystroke. This easy to use module offers 57.6K and 115.2K baud rates, and Ctrl-Alt-Del and Escape key reset outputs. Most non-ASCII keys are decoded as well into unique single byte codes.  US$16.99

E1832 Alphanumeric Display & Switch Interface
The E1832 Alphanumeric LCD Display Switch Interface uses only 3 microcontroller pins to write bytes to a standard 11 pin LCD interface and 2 pins to read two tactile switches such as for Select and Enter functions.  LCD instructions or data are sent serially as eight data bits plus the Register Select bit where they are converted to parallel format at the LCD connector. A single pulse on the LCD Enable completes the write.
