最新FreeRtos（版本8.0）上手指南

最近折腾一块stm32f107rc的板子，摸索了一下FreeRTOS 的使用

发现起步不太难有点经验和大家分享。freertos 8

1，先从官网下载 FreeRTOS 8.0.0

2，用标准库（STM32F10x_StdPeriph_Lib_V3.5.0）模板建工程

3, 在工程中添加FreeRTOS 文件。tasks.c list.c queue.c heap_2.c

port.c 其中port.C是cotex M3的移植文件。freertos 8选择目录..\..\Source\portable\RVDS\ARM_CM3\

下的port.c

3，修改启动代码（.s文件）如下，主要是链接FreeRTOS的三个中断函数

IMPORT xPortPendSVHandler

IMPORT xPortSysTickHandler

IMPORT vPortSVCHandler

.....

DCD vPortSVCHandler ; SVCall Handler

DCD DebugMon_Handler ; Debug Monitor Handler

DCD 0 ; Reserved

DCD xPortPendSVHandler ; PendSV Handler

DCD xPortSysTickHandler ; SysTick Handler

4.在main中建立自己任务开始 rtos

/* Create one task. */

xTaskCreate( vTask1, /* Pointer to the function that implements the task. */

"Task 1", /* Text name for the task. This is to facilitate debugging only. */

200, /* Stack depth in words. */

NULL, /* We are not using the task parameter. */

1, /* This task will run at priority 1. */

NULL ); /* We are not using the task handle. */

/* Create one task. */

xTaskCreate( vTask2, /* Pointer to the function that implements the task. */

"Task 2", /* Text name for the task. This is to facilitate debugging only. */

200, /* Stack depth in words. */

NULL, /* We are not using the task parameter. */

2, /* This task will run at priority 1. */

NULL ); /* We are not using the task handle. */

/* Start the scheduler so our tasks start executing. */

vTaskStartScheduler();

..............

..............

void vTask1( void *pvParameters )

{

/* As per most tasks, this task is implemented in an infinite loop. */

while(1)

{

LED_Toggle(0);

LED_Toggle(2);

vTaskDelay(800);

}

}

void vTask2( void *pvParameters )

{

/* As per most tasks, this task is implemented in an infinite loop. */

while(1)

{

LED_Toggle(1);

LED_Toggle(3);

vTaskDelay(1600);

}

}
