代码

修改hello world.c

选择helloworld@stm32l476rg-nucleo，修该helloworld.c

#include <stdio.h>

#include <aos/kernel.h>
#include <aos/hal/gpio.h>

gpio_dev_t LED1;
static void LED1_Off(void *arg);

static void LED1_On(void *arg)
{
    hal_gpio_output_high(&LED1);
    aos_post_delayed_action(100, LED1_Off, NULL);
}

static void LED1_Off(void *arg)
{
    hal_gpio_output_low(&LED1);
    aos_post_delayed_action(100, LED1_On, NULL);
}

int application_start(int argc, char *argv[])
{  
    LED1.port = 18;
    LED1.config = OUTPUT_PUSH_PULL;
    hal_gpio_init(&LED1);
    aos_post_delayed_action(1000, LED1_On, NULL);
    aos_loop_run();
    // while(1) {
    //     printf("hello world! count %d \r\n", count++);
    //     aos_msleep(1000);
    // };
}

编译下载，可以看到红色灯亮

修改hal_gpio_stm32l4.h

添加

然后把LED port改为72，绿色灯亮
