| Abstract: | This paper introduces a keyboard extending design scheme using the SPI of LingYang microprocessor. It realizes the management of keyboard by Zhou Li gong intelligent display chip ZLG7289 with SPI interface. The auxiliary circuit is simply-designed and easily-used, also it can manipulate many keys. This design occupies few I/O and can be widely used. The hardware circuit and flow chart of software as well as the simulation result are given in the paper. |
