15. Arduino learning notebook--Liquid crystal experiment of 12864 Juvtmall ( a company supply PCB Prototyping , PCBA service and sell kinds of components, modules and so on) ( Catduino has the same function of Arduino) 12864 is the lattice abbreviation of the 128*64 lattice liquid crystal module . Control chip generally adopts ST7920 or is compatible with it . The data bus adopts the way of 8-bit parallel port and SPI serial port. T he 12864 LCD zip font version with no font version . Font version does not need to enter again after the Chinese character s are became lattice with lattice generator, direct ly input the Chinese character interior code can show the corresponding Chinese characters . No font version want s to display Chinese characters, it only can be driven by its own way according to the lattice...
