STM32之FreeRTOS
简介 学习的硬件平台是基于正点原子的精英板。1. CubeMX创建FreeRTOS工程模板 选择芯片配置时钟及调试接口这种基本操作就不说了，直接从开始配置FreeRTOS工程模板说起。 ① 首先点击最下方的FreeRTOS选项② 点击v2版本，v1和v2有啥区别我不知道，可以自己试试
经过如上操作，FreeRTOS的工程模板就已经创建好了。
注意：如果使用FreeRTOS的话，它也是和HAL库一样用的sysTick作为系统时基，因此我们需要将HAL库的时基换一下，这里我使用的是定时器1。
跑马灯验证移植模板
现在我们可以验证一下我们的工程模板是否有问题，我们先玩个跑马灯，还是在CubeMX上配置任务，步骤如下：
第三步的操作是进行任务添加，设置任务名称任务堆栈任务优先级之类的，添加好了之后直接点击生成代码即可。 生成完毕之后打开MDK工程在文件freertos.c文件中的任务函数里添加如下代码（注意，是找到自己在CubeMX配置的任务函数名字，将函数的内容添加进去，不是直接将整个任务函数复制粘贴进去）： void Fun_LED1(void *argument)
{
/* USER CODE BEGIN Fun_LED1 */
/* Infinite loop */
for(;;)
{
HAL_GPIO_WritePin(LED1_GPIO_Port,LED1_Pin,GPIO_PIN_RESET);
osDelay(50);
HAL_GPIO_WritePin(LED1_GPIO_Port,LED1_Pin,GPIO_PIN_SET);
osDelay(50);
}
/* USER CODE END Fun_LED1 */
}
void Fun_LED2(void *argument)
{
/* USER CODE BEGIN Fun_LED2 */
/* Infinite loop */
for(;;)
{
HAL_GPIO_WritePin(LED0_GPIO_Port,LED0_Pin,GPIO_PIN_RESET);
osDelay(50);
HAL_GPIO_WritePin(LED0_GPIO_Port,LED0_Pin,GPIO_PIN_SET);
osDelay(50);
}
/* USER CODE END Fun_LED2 */
}
经过上面的例程，可以发现两个灯都是同时亮同时灭，看起来像是同一时刻执行两个任务（其实不是），示波器检测两个引脚的波形也是一致的，移植成功。 移植正点原子精英板TFTLCD程序代码
正点原子的例程都是根据标准库写的，在我们使用CubeMX工具配置的话就得需要经过一个移植来完成对LCD的控制。通讯时序我采用的是FSMC模拟产生8080时序来完成，主要分为两部分：
①：FSMC的配置
②：LCD的驱动及功能代码的移植 FSMC的配置
具体的FSMC配置如下：
同一器件，FSMC可以挂载4个，用片选引脚分开，这里我们选用块1的第四个区，也就是第2步所选的内容，采用与NOR FLASH通信的这块地址区域来模拟产生8080时序。这里我们主要关注的是第2步和第4步，因为这两个是根据硬件图来决定的，FSMC的数据线和地址线及其他的信号线都是固定的，因此这个我们不用管，我们需要关注的就是就是我们硬件中采用的是哪个区的那个片选，对应着不同的通信地址。我的板子上片选引脚连接的是PG12，对应FSMC的片选4，因此这里采用片选4。因为LCD屏没有地址线，但是有一个数据命令区分线，因此我们可以将LCD的数据命令区分线连接到其中的一根地址线，这里我的硬件连接是FSMC的A10地址线，对应GPIO的PG0。根据访问不同的地址A10地址线产生的高低电平来决定是给LCD写数据还是写命令（具体是哪个电平写数据哪个电平写命令是根据LCD的控制芯片来决定的）。 主要的地方配置好后就是第6项的数据命令等待时间及模式的配置，数据命令等待时间可以根据LCD时序图来配置，也可以使用经验值，模式我选得A模式。配置好之后就可以去控制我们的LCD了 LCD的驱动及功能函数的移植

//x,y:起点坐标
//width,height:区域大小
//size:字体大小
//*p:字符串起始地址

void LCD_ShowString(u16 x,u16 y,u16 width,u16 height,u8 size,u8 *p)
{
u8 x0=x;
width+=x;
height+=y;
while((*p<='~')&&(*p>=' '))//判断是不是非法字符!
{
if(x>=width){x=x0;y+=size;}
if(y>=height)break;//退出
LCD_ShowChar(x,y,*p,size,0);
x+=size/2;
p++;
}
}
//-----------------------------------------------------------------------------------------------------------------
以上便完成了对LCD驱动及功能函数的一个移植。
