stm32 freertos 开线程
freertos 开线程
主控芯片：stm32L031
通过stm32CubeMx加载freertos库，然后手动调用接口
#include "stm32f10x.h"
#include "FreeRTOS.h"
#include "task.h"
#include "queue.h"
#include "croutine.h"
#include "semphr.h"
// Lowest priority 0
#define TASK1_PRIORITY 1
#define TASK1_STACK_SIZE 512
#define TASK2_PRIORITY 2
#define TASK2_STACK_SIZE 512
TaskHandle_t task1_handler;
TaskHandle_t task2_handler;
static void task1(void * pvParameters)
{
for (;;) {
printf("%s\n", "task1");
vTaskDelay(1000);
}
}
static void task2(void * pvParameters)
{
for (;;) {
printf("%s\n", "task2");
vTaskDelay(1000);
}
}
static unsigned char task_init()
{
BaseType_t status = pdPASS;
status = xTaskCreate(task1,
"task1",
TASK1_STACK_SIZE,
NULL,
TASK1_PRIORITY,
&task1_handler);
status = xTaskCreate(task2,
"task2",
TASK2_STACK_SIZE,
NULL,
TASK2_PRIORITY,
&task2_handler);
return status;
}
int main()
{
if (task_init() == pdPASS)
vTaskStartScheduler();
for (;;) {
}
return 0;
}
上面的程序好像有点问题，需要根据单片机型号改大小和优先级

通过keil配置freertos有一篇文章可以看看KEIL自带操作系统验证例程在STM32上实现
但是我没有验证成功。
