The reason why i wanted to use HardwareSerial.h was to use UART.Read().
I am using the same arduino board as the sender and receiver.
Sender is the hardware 'tx' pin.
Receiver is any of the port pin of arduino.
program:
#include<NewSoftSerial.h> // for software serial pins
NewSoftSerial mySerial(2,3); // sets port pin 2 as software 'rx' and pin 3 as software 'tx'
char c;
void setup()
{
Serial.begin(9600); //sets baud rate for hardware UART
mySerial.begin(9600); //sets baud rate for oftware UART
}
void loop()
{
Serial.Print("Key1"); //data sent via hardware 'tx' pin
delay(1000);
if(mySerial.available()>0)
{
c=mySerial.Read(); //data read via software 'rx' pin
delay(1000);
}
}
I shorted the harware 'tx' and software 'rx' pins; also the harware 'rx' and software 'tx' pins. But this code did not work. I even tried the other way around. That is, transmit via software 'tx' and receive via harware 'rx'. But that too did not work. The code for this arrangement is here:
void loop()
{
Serial.myPrint("Key1"); //data sent via software 'tx' pin
delay(1000);
if(Serial.available()>0)
{
c=Serial.Read(); //data read via hardware 'rx' pin
delay(1000);
}
}
