鸿蒙开发板Hi3861_点亮LED开关实验——基于code-2.0-CANARY金丝雀windows下编译

鸿蒙开发板Hi3861_点亮LED开关实验

1.vscode 创建一个led_demo2文件夹

2. led_demo2文件夹下面在创建两个文件led2.c和BUILD.gn

led2.c内容：

#include <stdio.h>
#include "ohos_init.h"
#include "cmsis_os2.h"
#include "iot_gpio.h"
//#include "wifiiot_gpio_ex.h"

//#define 

//static void LedTask(void *arg)
static void LedTask(void *arg)
{
    (void) arg;
    //GpioInit(9);
    IoTGpioInit(9);
    //IoSetFunc(9,IOT_GPIO_DIR_OUT);
    IoTGpioSetDir(9,IOT_GPIO_DIR_OUT);
   // osDelay(50);
   while(1)
   {
       IoTGpioSetOutputVal(9,IOT_GPIO_VALUE0);
        osDelay(100);
       printf("pin9 OFF\n");
      
       //usleep(10000000);
       IoTGpioSetOutputVal(9,IOT_GPIO_VALUE1);
        osDelay(100);
       printf("pin9 ON\n");
      // usleep(10000000);
      
   }
    
}
static void LedEntry(void)
{
    osThreadAttr_t attr={0};
    attr.name="LedTask";
    attr.stack_size=4096;
    attr.priority=osPriorityNormal;
    if(osThreadNew(LedTask,NULL,&attr)==NULL)
    {
        printf("[LedEntry] create LedTask failed!\n");
    }
}
SYS_RUN(LedTask);

BUILD.gn

static_library("led_demo2") {
    sources = [ "led2.c"]

    include_dirs = [
        
        "//third_party/cmsis/CMSIS/RTOS2/Include",
         "//utils/native/lite/include",
        "//kernel/liteos_m/components/cmsis/2.0",
        "//base/iot_hardware/peripheral/interfaces/kits",
        ]
}

app的目录的BUILD.gn
