关于softwareserial中的例程TwoPortReceive
#include <SoftwareSerial.h>SoftwareSerial portOne(10, 11);
SoftwareSerial portTwo(8, 9);
void setup()
{
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
portOne.begin(9600);
portTwo.begin(9600);
}
void loop()
{
portOne.listen();
Serial.println("Data from port one:");
while (portOne.available() > 0) {
char inByte = portOne.read();
Serial.write(inByte);
}
Serial.println();
portTwo.listen();
Serial.println("Data from port two:");
while (portTwo.available() > 0) {
char inByte = portTwo.read();
Serial.write(inByte);
}
Serial.println();
}

为了帮助我理解TwoPortReceive这个程序，我又写了TwoPortSend程序，代码如下：
#include <SoftwareSerial.h>
SoftwareSerial portOne(10, 11);
SoftwareSerial portTwo(8, 9);
void setup()
{
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
portOne.begin(9600);
portTwo.begin(9600);
}
void loop()
{
portOne.println("1");
portTwo.println("2");
}
-----------------------------------------------------------------------------
将这两段程序分别烧录到两块arduino uno主板上，烧录有TwoPortReceive程序的arduino主板连接至电脑，烧录有TwoPortSend程序的arduino主板连接至烧录有TwoPortReceive程序的arduino主板，结果发现串口监视器显示一片乱码。将TwoPortReceive程序去掉有关portOne或portTwo的代码，串口监视器正常显示portTwo或portOne发来的信息。
请问我如何既能收portone又能收porttwo的信息？
