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
");
//usleep(10000000);
IoTGpioSetOutputVal(9,IOT_GPIO_VALUE1);
osDelay(100);
printf("pin9 ON
");
// 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!
");
}
}
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
