stm32中清空数组

在STM32中清空数组可以采用以下几种方法:
1. 使用循环方法:
```
char a[] = "aaaaaaaa"; //定义字符数组
for (unsigned int i = 0; i < strlen(a); i++) {
a[i = '\0'; //for循环清空数组
}
```
2. 使用memset函数:
```
char a[] = "aaaaaaaa"; //定义字符数组
memset(a, 0, sizeof(a)); //清空数组
```
3. 使用strcpy函数:
```
char ss = "hello world"; //当前为hello world
strcpy(ss, ""); //现在的ss就是空串了
```
以上是在C语言中清空字符数组的方法。如果你是在JavaScript中使用STM32,可以采用以下几种方法:
1. 使用splice方法清空数组:
```
var arr = [1, 3];
arr.splice(0); //第一种清空数组方法
```
2. 使用设置数组长度为0的方式清空数组:
```
var arr = [1, 3];
arr.length = 0; //第二种清空数组方法
```
3. 直接将数组赋值为空数组:
```
var arr = [1, 3];
arr = []; //第三种清空数组方法
```
请根据你的具体需求选择适合的方法来清空数组。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
