stm32 to arduino serial communication
问题
I am sending my adc values to an arduino board via UART.
sprintf(data," ADC1= %d ADC2= %d \n", adcData[0], adcData[1]);//working
HAL_UART_Transmit(&huart2, (uint8_t*)data, strlen(data), 1000); //working
HAL_Delay(500);
and my outputs as like this in Tera Term screen;
my arduino while loop as follows;
incomingByte = Serial.read(); // read the incoming byte:
String myString = String(incomingByte);
Serial.print(" I received:");
Serial.println(myString);
And the outputs do not match my adc values 
What should I do to see my values as I sent.

要查看您发送的值，您应该将数据中继如其发送。
int incomingByte = Serial.read(); // 读取传入的字节：
if (incomingByte >= 0) { // 如果有输入
Serial.write(incomingByte); // 打印接收到的内容
}
英文:
To see your values you sent, you should relay the data as it is sent.
int incomingByte = Serial.read(); // read the incoming byte:
if (incomingByte >= 0) { // if there is some input
Serial.write(incomingByte); // print what is received
}
