How to Modify the TX and RX pin for SoftwareSerial #5

In my project, I was using a TFT LCD screen shield along with sim800 module, hence not able to use digital pin 8 and 9. Is there any method to modify this by using barebonesim800.h or AltSoftSerial.h?

You can attempt to change the library to use SoftwareSerial and use any two pins of your choice, but I won't recommend that since it can conflict with other libraries.

Use this newly modified files, replace the old .h and .c files in the library. barebone_temp_fix.zip

You can change the Pins used for communication in this section -

 #include "Arduino.h"

 #define RX_PIN 10      //not needed since the AltSoftSerial has already define it inside
 #define TX_PIN 11
