| Abstract: | This paper introduces a method to design special keyboard for toll collection system of highway with MCS-51 single-chip microcomputer. The design uses single-chip microcomputer as control circuit core to constitute determinant keyboard, and uses scanning procedure method to recognize the key pressed down, and communicate cross the MCS-51 single-chip microcomputer and PC correspondence serial port. |
