(0026) 实验内容：
(0027) 初始化、读写Lcd12864_ST7920。
(0028) ----------------------------------------------------------------------
(0029) 硬件连接：

(0031) 1.GND -------- GND
(0032) 2.VCC -------- VCC
(0033) 3.V0 -------- V0
(0034) 4.RS(CS) -------- VCC

(0051)
(0052) 操作步骤：
(0053) (1)编译烧写该程序到ATmega16，断开电源
(0054) (2)若使用ISP接口烧写程序，请断开ISP烧写器
(0055) （由于本示例程序使用的是ATmega16的SPI接口，刚好是ISP烧写器的烧写口）
(0056) (3)将LCD12864_ST7920插入主板的Lcd12864插槽
(0057) (4)使用连接线将LCD12864_ST7920的以下引针接口连接到MCU：
(0058) （由于SMK1632已经做好了大部分的硬件连接，您只需连接以下数据端口）
(0059) LCD12864_ST7920 ATmega16
(0060) 4.RS(CS) -------- VCC
(0061) 5.R/W(SID) -------- MOSI/PB5
(0062) 6.E(SCLK) -------- SCK/PB7
(0063) 15.PSB -------- GND
(0064) (5)上电，如果操作正确，这时您可以看到显示的内容了
