串行读取更改输入，不读取整行

使用 ArduinoUno 和 Arduino IDE 无法正确读取通过串行发送的大字符串。当键入的命令太长时，不会返回整个数据，有时甚至是随机数。

99,3,0,1,0,0,0结果正确(不确定为什么会有结尾,(：receivedValues are: 99,3,0,1,0,0,0,

99,3,0,0,0,0,0正确结果：receivedValues are: 99,3,0,0,0,0,0,

哪里开始出错：

99,3,0,100,200,300,400结果：receivedValues are: 99,3,0,100,200,44,144,

99,123456789结果在：receivedValues are: 99,21,0,1,200,200,244,

99,3,0,1,200,200,2000结果在：receivedValues are: 99,3,0,1,200,200,208,

这是我的代码中相关的部分：

uint8_t receivedValues[7] = {0, 0, 0, 0, 0, 0, 0};
#define HEADER 0 // 99
#define CMD   1 // LICHT (2)   || GEUR (3)
#define DATA0 2 // KLEUR INDEX || GEUR INDEX
#define DATA1 3 // H           || ON / OFF
#define DATA2 4 // S
#define DATA3 5 // V
#define DATA4 6 // BlendTime
#define CHECK 99
#define ON 1
#define OFF 0
bool messageReceived = false;
bool startBlending = false;
void setup()
{
Serial.begin(9600);
}
void loop()
{
ParseSerial();
if (messageReceived)
{
printMessage();
// CheckCommand();
messageReceived = false;
}
}

void ParseSerial()
{
int serialIndex = 0;
if (Serial.available() > 8)
{
while (0 < Serial.available())
{
String bufferString;
int bufferInt;
bufferString = Serial.readStringUntil(',');
bufferInt = bufferString.toInt();
receivedValues[serialIndex] = bufferInt;
serialIndex++;
}
if (receivedValues[HEADER] == CHECK)
{
Serial.print("receivedValues[0]: ");
Serial.println(receivedValues[0]);
messageReceived = true;
}
if (receivedValues[HEADER] != CHECK)
{
Serial.println("not a good package");
}
Serial.flush();
}
else
{
Serial.flush();
}
}
void printMessage()
{
Serial.print("receivedValues are: ");
for (int i = 0; i < 7; i++)
{
Serial.print(receivedValues[i]);
Serial.print(",");
}
Serial.println();
}

如果消息的标头不以99开头，它将写入not a good package。值得注意的是，当我在开头输入带有99的命令时，它大部分时间都会写两次not a good package。
