stm32 字符串截取

在STM32中进行字符串截取可以使用C语言中的字符串处理函数来实现。你可以使用strtok函数将字符串按照指定的分隔符进行分割，然后获取到你需要的子字符串。下面是一个示例代码：

#include <stdio.h>
#include <string.h>

int split(char dst[][80], char* str, const char* spl) {
    int n = 0;
    char *result = NULL;
    result = strtok(str, spl);
    while( result != NULL ) {
        strcpy(dst[n], result);
        result = strtok(NULL, spl);
        n++;
    }
    return n;
}

int main() {
    char str[] = "what is your name?";
    char dst<span class="em">1</span><span class="em">2</span><span class="em">3</span>
