| Abstract: | This paper mainly describes apparatus design for Four-wire resistance touch screen interface chip ADS7843 based on ATmega128 single-chip microcomputer.ADS7843 communicates with ATmega128 by SPI bus,and then obtains positions of touch screen which can represent coordinates of LCD.If there is a defined key,the program will call the key_service functions. |
