[TM4C123 with I2C LCD Display]

Hello, everyone! Has anyone used the I2C display module with the TM4C123 Launchpad? I'm trying to use this code as a test, but I was not successful. The version of the library I am using is 1.2.1
I accept other suggestions for using the i2c display. 

Thanks in advance! 

The code:

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

// Start the I2C address at 0x27 position
LiquidCrystal_I2C lcd(0x27,2,1,0,4,5,6,7,3, POSITIVE);
 
void setup()
{
 lcd.begin (16,2);
}
 
void loop()
{
  lcd.setCursor(0,0);
  lcd.print("test line 1");
  lcd.setCursor(1,1);
  lcd.print("test line 2");
}

The error:

[SIM800L using TM4C123GXL and Energia]

Thank you, Fmilburn! I was wrong when I was trying to use the library SoftwareSerial.h. Now just using Serial3.begin and etc and looking the arm's pin map, the program is working. Thank you one more time! 

[SIM800L using TM4C123GXL and Energia]

Hello everyone! I am using the SIM800L module to send SMS through a TivaC TM4C123GXL board, but its clock is 80MHz, and the library only accepts 20, 16 or 8 MHz. In Arduino it worked perfectly, this code found on a website. How do I reduce the TM4C123 clock in Power software? Is there another solution? Thanks in advance!
 

The code:

#include <SoftwareSerial.h>
SoftwareSerial sim(3, 4);
int _timeout;
String _buffer;
String number = ""; //here I inserted my number phone
void setup() {
  delay(4000); //delay for 7 seconds to make sure the modules get the signal
  Serial.begin(9600);
  _buffer.reserve(50);
  Serial.println("Sistem Started...");
  sim.begin(9600);
  delay(1000);
}
void loop() {
  SendMessage();
  delay(10000);
}
void SendMessage()
{
  //Serial.println ("Sending Message");
  sim.println("AT+CMGF=1");    //Sets the GSM Module in Text Mode
  delay(1000);
  //Serial.println ("Set SMS Number");
  sim.println("AT+CMGS=\"" + number + "\"\r"); //Mobile phone number to send message
  delay(1000);
  String SMS = "Testing GSM module";
  sim.println(SMS);
  delay(100);
  sim.println((char)26);// ASCII code of CTRL+Z
  delay(1000);
  _buffer = _readSerial();
}
String _readSerial() {
  _timeout = 0;
  while  (!sim.available() && _timeout < 12000  )
  {
    delay(13);
    _timeout++;
  }
  if (sim.available()) {
    return sim.readString();
  }
}
