2. 编写函数将String转换为uint8_t数组 要将String转换为uint8_t数组,我们需要遍历字符串中的每个字符,并将其转换为uint8_t类型。以下是一个示例函数,实现了这一转换: cpp #include <Arduino.h> // 函数声明 uint8_t* stringToUint8Array(const String& str, uint8_t* buffer, size_t buff...

关于arduino:将char数组转换为String Transform char array into String 我有一个返回char数组的函数,我希望将其转换为String,以便更好地处理它(与其他存储的数据进行比较)。 我使用这个简单的方法应该可以工作,但是由于某些原因(bufferPos是数组的长度,buffer是数组,item是一个空字符串),它不起作用:...
