MM32F031开发板评测8：模拟SPI驱动2.2寸SPI屏
<div class='showpostmsg'>有的人看到模拟SPI会不屑一顾，有些甚至看都不看，我确高兴的很，原因何在？？？我是个看结果的人，也就是说一但我哪一天开发SPI的东东开发不出来了。也不会象《春天里》那首歌唱的，死在春天里。我应百折不挠地用模拟串口实现。
费话不说了，上图：
以下的是清红色的屏，那叫一个红。
那么怎么搞定的呢？很简单只要有这个屏的资料。下面是这个SPI屏的资料一并传上：
把里边的STMF103例程里边的驱动及H文件考到点灯那个程序目录里。然后添加，然后编译。
至于，线怎么连其实H文件里边有，其顺序如下；
B12-----CS
A4----RES
B1----DC
B13----CLK
B15-----DIN
以下是主函数：
int main(void)
{
delay_init();
LED_Init();
LCD_GPIO_Init();
Lcd_Init();
Lcd_Clear(RED);
while(1) //ÎTÏTÑ-»·
{
LED1_TOGGLE();
LED2_TOGGLE();
LED3_TOGGLE();
LED4_TOGGLE();
delay_ms(1000);
}
}
