系统实验板原理图掌握七段码显示器硬件线路原理掌握用HD7279A 芯片
实现显示的编程方法
HD7279A 是一片具有串行接口的,可同时驱动8 位共阴式数码管(或64 只独立LED)的
智能显示驱动芯片该芯片同时还可连接多达64 键的键盘矩阵
HD7279A 内部含有译码器可直接接受16 进制码HD7279A 还同时具有2 种译码方
式HD7279A 还具有多种控制指令如消隐闪烁左移右移段寻址等-System board schematic master code display hardware and seventh line with the principle of master chip HD7279A Programming HD7279A shown is the one with the serial interface, can drive a total of 8 vaginal digital tube (or 64 independent LED) of the smart display driver chip at the same time the chip can connect up to 64 key internal keyboard matrix containing HD7279A decoder can accept the 16 hexadecimal code directly HD7279A also have two kinds of decoding methods HD7279A also has a variety of control commands, such as blinking blanking shifted to right above the left, such as addressing
