资料介绍
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
