freertos任务参数

实现多个任务利用同一个函数，传进不同的任务参数，打印不同的任务内容。多个人用同一个电脑干不同工作，美工用电脑干美工，程序员用电脑敲代码

#include "stm32f10x.h"                  // Device header
#include "freertos.h"
#include "task.h"
#include "usart.h"TaskHandle_t myTaskHandler1;
TaskHandle_t myTaskHandler2;
TaskHandle_t myTaskHandler3;
TaskHandle_t startTaskHandler;void myPrintf(void* arg){char* str=arg;while(1){taskENTER_CRITICAL();printf("%s\n",str);taskEXIT_CRITICAL();vTaskDelay(500);}
}
void startTask(void* arg){taskENTER_CRITICAL();printf("start running\n");taskEXIT_CRITICAL();xTaskCreate(myPrintf, "myTask", 128, "myTask1", 2, &myTaskHandler1); xTaskCreate(myPrintf, "myTask", 128, "myTask2", 2, &myTaskHandler2); xTaskCreate(myPrintf, "myTask", 128, "myTask3", 2, &myTaskHandler3); vTaskDelete(NULL);
}
int main(void){USART_Config();xTaskCreate(startTask,"startTask",128,NULL,2,&startTaskHandler);vTaskStartScheduler();while(1){}}StaticTask_t	IdleTaskTCB;
StackType_t		IdleTaskStack[configMINIMAL_STACK_SIZE];
void vApplicationGetIdleTaskMemory( StaticTask_t 	**ppxIdleTaskTCBBuffer, StackType_t 	**ppxIdleTaskStackBuffer, uint32_t 		*pulIdleTaskStackSize )
{*ppxIdleTaskTCBBuffer = &IdleTaskTCB;*ppxIdleTaskStackBuffer = IdleTaskStack;	*pulIdleTaskStackSize = configMINIMAL_STACK_SIZE;}
