سلام
میتونی دو تا softwareserial تعریف کنی
فقط یه نکته داره اونم اوینه که دقیقا و همزمان نمیتونن ارسال کنن
یه delay حدود 10 میلی بزاری احت جواب میگیری
برای کدش هم از نمونه دوم مثال کتابخونه softwareserial استفاده کن .
نمونه کدش اینه :
کد:
#include <SoftwareSerial.h>
// software serial #1: RX = digital pin 10, TX = digital pin 11
SoftwareSerial portOne(10, 11);
// software serial #2: RX = digital pin 8, TX = digital pin 9
// on the Mega, use other pins instead, since 8 and 9 don't work on the Mega
SoftwareSerial portTwo(8, 9);
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
// Start each software serial port
portOne.begin(9600);
portTwo.begin(9600);
}
void loop() {
// By default, the last intialized port is listening.
// when you want to listen on a port, explicitly select it:
portOne.listen();
Serial.println("Datfrom port one:");
// while there is data coming in, read it
// and send to the hardware serial port:
while (portOne.available() > 0) {
char inByte = portOne.read();
Serial.write(inByte);
}
// blank line to separate data from the two ports:
Serial.println();
// Now listen on the second port
portTwo.listen();
// while there is data coming in, read it
// and send to the hardware serial port:
Serial.println("Data from port two:");
while (portTwo.available() > 0) {
char inByte = portTwo.read();
Serial.write(inByte);
}
// blank line to separate data from the two ports:
Serial.println();
}
