【STM32F0实验】+Nokia5110液晶显示

昨晚研究了一晚上，在STM32F1xx的固件库文档的帮助下，成功实现了Nokia5110液晶的简单显示主函数代码

int main(void)

{

        Clock_Init();

  GPIO_LCD_Init();

        LCD_Init();

  while(1)

  {  

    LCD_Write_Num(0 ,0 ,1234,5);

  }

void Clock_Init(void)

{

        ErrorStatus HSEStartUpStatus;

        /* Enable HSE */

        RCC_HSEConfig(RCC_HSE_ON);

        /* Wait till HSE is ready and if Time out is reached exit */

        HSEStartUpStatus = RCC_WaitForHSEStartUp();

        if(HSEStartUpStatus == SUCCESS)

        {

        /* Set PLL clock output to 24MHz using HSE (8MHz) as entry clock */

        RCC_PLLConfig(RCC_CFGR_PLLSRC_PREDIV1, RCC_PLLMul_3);

        /* Enable the PLL */

        RCC_PLLCmd(ENABLE);

        RCC_PCLKConfig(RCC_HCLK_Div2);



        /* Enable GPIOA clocks */

        RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE);

        }

        else

        {

痛苦的是下载太难下进去了，我下载了这么多次，只有那一次成功了
我使用的是外部8M晶振，从上面的时钟初始化也能看出来

:funk:!LZ真快，我也是昨天搞定了5110，还没有来得及发帖，被你占先了。

更新一下显示图片
图片显示取模必须是：数据水平，字节垂直方式
取模方式不对，图形显示是乱码
LCD_draw_bmp_pixel(0,0,gImage_j,64 ,40);  //图像取模时，数据水平，字节垂直

ST图形**的数组：

图片效果在楼主位

我还不知道怎么搞

5# 梦中花雨 这个可以参考下论坛上的资料吧，我看有很多牛人都发了资料上来
多看看就应该会了吧

程序烧不进去啊~~~求教

!LZ真快，我也是昨天搞定了5110，还没有来得及发帖，被你占先了。

新手 请教一下5110LCD，在STM32F030F4P6上显示，能给个代码么？多谢。

这个，看着不错了，就是有人说程序烧的难，真不明白为何这样

时序问题，我也写过5110的程序，经常使能端上去了，spi还没发送完，需要延时

时序问题，我也写过5110的程序，经常使能端上去了，spi还没发送完，需要延时 ...

应该添加个while循环，直到发送完了跳过

调试成功，谢谢楼主，不过代码里缺了一个 时钟         RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE);

这代码怎么写出来的，楼主是个大神啊

楼主大神啊，赞一个

不错不错

这代码是写出来的，还是移植的，大神啊

软件模拟SPI,看来都是从51上移植过来的。

不知道
