原创 用最新库玩转智林STM32开发板(之四)------点亮真彩屏

驱动智林STM32开发板，真彩屏首先设定PINC为输出
所有子函数都在TFT018.c中
编译运行,则在屏幕显示如下:

STM32F  EVAL  BOARD

   Version 1.0

  ZERO  Research

www.the0.net
整个工程有如下文件:

Source Group1
             STM32f10x.s
lcd:
             TFT018.c
uinit:
             main.c
lib:
             stm32f10xR.lib(这个不用编,是MDK目录下的库文件包进来就行)

大家可把main.c直接考到工程中

很好的买家,合作非常愉快,希望再次惠顾小店
