TM4C123GH6PM: GPIOPinConfigure() function not working


Recommended Posts

Hi. I seem to get the following error whenever I try using "GPIOPinConfigure()" as shown below:

 

 

 

However I do NOT get the error whenever the function "GPIOPinConfigure()" is NOT used:

 

 

 

In essence, I want to be able to make a SSI connection with two TM4C123GH6PM launchpads in order to send temperature information (from one end) and print it onto a Kentec LCD screen (at the other end). The complete code of the sender is posted in the following:

 

#include <LiquidCrystal.h>
 
#include <DHT.h>
 
#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_memmap.h"
#include "inc/hw_types.h"
#include "driverlib/gpio.h"
#include "driverlib/pin_map.h"
#include "driverlib/sysctl.h"
#include "driverlib/uart.h"
 
#include "inc/hw_ints.h"
#include "driverlib/interrupt.h"
 
 
#define DHTPIN PF_0  // GPIO pin for data
#define DHTTYPE DHT22  //Type of sensor (DHT11 or DHT22)
 
DHT dht(DHTPIN, DHTTYPE);
//LCD Print
LiquidCrystal lcd(PD_1, PD_2, PD_3, PE_1, PE_2, PE_3);
void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200); //Serial Baud rate
  Serial.println("DHT22 test!");
 
  dht.begin();
 
  lcd.begin(16, 2);
  lcd.print("TEST");
  delay(2000);
  lcd.clear();
 
}

    ui32Status = UARTIntStatus(UART0_BASE, true); //get interrupt status
    UARTIntClear(UART0_BASE, ui32Status); //clear the asserted interrupts
 
    while(UARTCharsAvail(UART0_BASE)) //loop while there are chars
    {

        //echo character

        IntMasterEnable();
        IntEnable(INT_UART0);
        UARTIntEnable(UART0_BASE, UART_INT_RX | UART_INT_RT);*/
 
  lcd.noDisplay();
  delay(200);
  lcd.display();
  delay(200);
  
  delay(2000);
 
  float h = dht.readHumidity();
  float t = dht.readTemperature();
  float f = dht.readTemperature(true);
  if (isnan(h) || isnan(t) || isnan(f)) {
    Serial.println("Failed to read from DHT sensor!");
    return;
  }
 
  // Prints results on serial monitor
  Serial.print("Humidity: ");
  Serial.print(h);
  Serial.print(" %\t");
  Serial.print("Temperature: ");
  Serial.print(t);
  Serial.print(" *C");
  Serial.print(", ");
  Serial.print(f);
  Serial.println(" *F "); 
 
 // Prints on LCD
  lcd.setCursor(0, 1);
  lcd.print("HUMID% = ");
  lcd.print(h);
  lcd.println(" %" );
    
  lcd.setCursor(1, 0);
  lcd.print(" TEMP = ");
  lcd.print(t);
  lcd.println("*C"); 
}
 

 I hope someone can help me address this error. Thank you.
