有智林板的可以把所有文件考到一个目录下边,工程非常简单只包括三个文件 main.C//主文件 TFT018.c//显示有关文件 STM32F10XR.LIB//这个文件在MDK目录下边很好找 智林开发板板载上,下,左,右,方向键,若直接按,就是OK,本程序只是设置好上拉电阻输入就行, 运行时可即时显示用户的按键,本例有HEX可直接下载到芯片里边
以下是主程序:
int main(void) { #ifdef DEBUG debug(); #endif /* System Clocks Configuration */ RCC_Configuration(); /* NVIC Configuration */ NVIC_Configuration(); /* GPIO Configuration */ GPIO_Configuration();
