LCD1602B基本驱动函数库

1、需要底层硬件驱动函数支持

基本的宏定义：

LCD_RS LCD_RW LCD_E

LCD_SetWriteData LCD_SetReadData

LCD_HalfData_Port LCD_HalfData_DDR

LCD_SendHalfCharHigh(a)

LCD_SendHalfCharLow(a)

2、需要基本的延时函数支持基本的延时函数：

DelayMs() 毫秒 DelayUs() 微妙

3、需要修改引用宏定义来指定底层硬件驱动 函数库。

4、该头文件支持4位发送模式，硬件连接4位

8位都支持。 -LCD1602B basic functions a driver, the underlying hardware drivers needed to support the basic functions of Acer definition : LCD_RS LCD_RW LCD_E LCD_SetWriteData LCD_SetReadData LCD_HalfData_Port LCD_HalfData_DDR LCD_SendHalfCharHigh (a) LCD_ SendHalfCharLow (a) 2, the basic needs of the time-delay function to support the basic functions of the delay : DelayMs () millisecond DelayUs () three delicate, Acer cited a need to amend the definition to specify the underlying hardware-driven functions. 4, the first four documents to support this model, the hardware connecting four eight support.
