/********************************************************** * @ File name -> lcd12864.c * @ Version -> V1.1
* @ Date -> 07-15-2017
* @ Brief -> LCD12864驱动函数
* 适用于ST7920驱动芯片
V1.0
* @ Revise -> A、修正操作命令宏定义。 * @ -> B、显示字符串函数增加显示长度选择，即显示多少个ASCII可显示字符，汉字x2即可
* @ -> C、去掉显示数组函数，合并在字符串显示里
V1.1
* @ Revise -> A、增加STM32硬件SPI控制接口
* @ -> B、修正STM32并口控制LCD12864接口(但未测试)
