----------------------------------------------------------------------
版本更新记录:
----------------------------------------------------------------------
实验内容:
初始化、读写Lcd1602。
----------------------------------------------------------------------
硬件连接:
将Lcd1602插入主板的Lcd1602插槽,
使用连接线将LCD1602的引针接口连接到MCU:
//LCD1602,4位接口,即使用D4-D7数据口,D0-D3不接入MCU
//PIN1 --- GND
//PIN2 --- VCC
//PIN3 --- V0
//PIN4 --- RS --- PB5
//PIN5 --- R/W --- PB6
//PIN6 --- E --- PB7
//PIN7 --- D0
//PIN8 --- D1
//PIN9 --- D2
//PIN10 --- D3
//PIN11 --- D4 --- PD4
//PIN12 --- D5 --- PD5
//PIN13 --- D6 --- PD6
//PIN14 --- D7 --- PD7
//PIN15 --- VCC
//PIN16 --- GND
----------------------------------------------------------------------
注意事项:
(1)若有加载库函数,请将光盘根目录下的“库函数”下的“ICC_H”文件夹拷到D盘
(2)请详细阅读“使用必读”及相关资料。
