Serial.readBytesUntil()将串行缓冲区中的字符读入数组。 如果检测到终止符字符,确定的长度已被读取或超时(参见Serial.setTimeout()),该函数将终止。 Serial.readBytesUntil()返回读入缓冲区的字符数。 A 0表示没有找到有效的数据。 Serial.readBytesUntil()从Stream实用程序类继承。 语法:Serial.readBytesUntil(cha...
All the bytes received until ‘\n’ are automatically converted and added in an Arduino String object.Then, we just print back the data we received, with an additional piece of text.Note: if you want to read bytes one by one, you can do so with the Serial.read() function. Then you...
You can use the following statement to discard all data in the receive buffer: while(Serial.read() >= 0) ; // flush the receive buffer. Serial.write and Serial.print do not block. Older versions of Arduino would wait until all characters were sent before returning. Instead, characters ...
