Using only TX of SoftwareSerial, leaving RX pin free

system · March 22, 2014, 4:27pm

I adapted SoftwareSerial to only have a send function. Download library here:

http://gammon.com.au/Arduino/SendOnlySoftwareSerial.zip

Example of use:
#include <SendOnlySoftwareSerial.h>

SendOnlySoftwareSerial mySerial (3);  // Tx pin

void setup ()
  {
  mySerial.begin(115200);
  }
 
int i;

void loop ()
{
  mySerial.print ("test: ");
  mySerial.println (i++);
  delay (100);
}

in my case I want to release TX pin
how I can change the library in order to implement this method?
