stm32f103rct6程序例子以stm32f103rct6程序例子为题，我们来介绍一些关于该例子的内容。

1. 引言在这个例子中，我们将使用stm32f103rct6微控制器来实现一个简单的LED闪烁程序。

该程序将通过设置GPIO引脚状态来控制LED的亮灭。

2. 初始化设置我们需要进行初始化设置。

我们将使用stm32的库函数来配置GPIO 引脚和时钟。

代码如下：```c#include "stm32f10x.h"void GPIO_Init(void){GPIO_InitTypeDef GPIO_InitStructure;RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC, ENABLE);GPIO_InitStructure.GPIO_Pin = GPIO_Pin_13;GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;GPIO_Init(GPIOC, &GPIO_InitStructure);}```在上述代码中，我们使用GPIOC的第13号引脚作为输出引脚，并将其配置为推挽输出模式。

3. 主函数接下来，我们将在主函数中实现LED闪烁的逻辑。

代码如下：```cint main(void){GPIO_Init();while(1){GPIO_SetBits(GPIOC, GPIO_Pin_13);Delay(1000000);GPIO_ResetBits(GPIOC, GPIO_Pin_13);Delay(1000000);}}```在上述代码中，我们使用GPIO_SetBits()函数将GPIOC的第13号引脚设置为高电平，从而点亮LED。

然后，我们使用Delay()函数进行延时，以保持LED亮的时间。

lcd12864 程序流程图
我们常用的人机交互显示界面中，除了数码管，LED，以及我们之前已经提到的LCD1602 之外，还有一种液晶屏用的比较多。

相信接触过单片机的朋友都知道了，那就是12864 液晶。

顾名思义，12864 表示其横向可以显示128 个点，纵向可以显示64 个点。

我们常用的12864 液晶模块中有带字库的，也有不带字库的，其控制芯片也有很多种，如KS0108 、T6963，ST7920 等等。

在这里我们以ST7920 为主控芯片的12864 液晶屏来学习如何去驱动它。

（液晶屏采用金鹏的OCMJ4X8C）。

lcd12864 液晶说明：
我们先来了解一下它的并行连接情况。

下面是电路连接图：
上面的图可以看出，液晶模块和单片机的连接除了P0 口的8 位并行数据线之外，还有RS，RW，E 等几根线。

其中R/S 是指令和数据寄存器的选择控制线（串行模式下为片选），R/W 是读写控制线（串行模式下是数据线），E 是使能线（串行模式下为时钟线）。

通过这几根控制线和数据线，再结合它的时序图，我们就可以编写出相应的驱动程序啦。

看看并行模式下的写时序图：。

12864液晶屏串口驱动程序代码12864液晶屏驱动采用4_Wire-SPI串口驱动方式，可有效的减少IO口的占用，方便使用调试，本程序的代码驱动IC为ST7565R,是基于STC89C53RC的12864串行模式的程序，硬件电路连接只需要5根线：RS、 SDA、 SCLK、RES、CS 。

程序已经调试通过，很好用。

LCD12864液晶驱动编程指南
1.连接硬件：
2.初始化液晶：
在开始使用液晶之前，需要进行初始化。

初始化过程包括设置液晶的
工作模式、显示模式和其他参数。

通过向液晶发送一系列的指令，可以完
成初始化过程。

3.编写驱动程序：
液晶驱动程序的主要目的是将需要显示的内容以及液晶的控制指令发
送给液晶屏。

根据液晶屏的通信方式，可以采用单片机的IO口直接控制
液晶屏，也可以通过SPI或I2C等接口芯片间接控制。

4.显示图形：
5.显示文本：
除了图形外，液晶还可以显示文本。

可以通过设置显示位置和发送需
要显示的文本来实现。

6.更新显示：
当需要更新液晶上的内容时，可以通过重新设置显示的内容和刷新液
晶来实现。

可以定时刷新液晶，或者通过检测外部事件来触发刷新。

7.扩展功能：
除了基本功能外，还可以实现一些扩展功能，如显示动画、滚动显示、倒计时等。

只需要根据需求编写相应的代码即可实现。

总结：
注意事项：
在编写驱动程序时，需要注意及时更新液晶上的内容，避免频繁刷新导致的卡顿现象。

同时，为了保证程序的可移植性，可以将液晶驱动程序与其他功能模块进行分离，便于代码的维护和移植。
