serialEvent1on CC3200

Recommended Posts

I'm trying to receive data in serial1 on CC3200 launchpad and send the data to serial0 for serial monitor. In my code, serialEvent1 don't work. Anyone has a solution for this? What is wrong, please?

String inputString = ""; // a string to hold incoming data
boolean stringComplete = false; // whether the string is complete

void setup()
{
  // put your setup code here, to run once:
  Serial.begin(1200);
  Serial1.begin(1200);
  pinMode(GREEN_LED,INPUT);

  // reserve 200 bytes for the inputString:
  inputString.reserve(200); 

}

void loop()
{
  // print the string when a newline arrives:
  if (stringComplete) {
    Serial.println(inputString); 
    // clear the string:
    inputString = "";
    stringComplete = false;
  }
}

/*
  SerialEvent occurs whenever a new data comes in the
  hardware serial RX. This routine is run between each
  time loop() runs, so using delay inside loop can delay
  response. Multiple bytes of data may be available.
*/
void serialEvent1() {

  while (Serial1.available()) {
    // get the new byte:
    char inChar = (char) Serial1.read(); 
    // add it to the inputString:
    inputString += inChar;
    // if the incoming character is a newline, set a flag
    // so the main loop can do something about it:
    if (inChar == '\n') {
    stringComplete = true;
    } 
  }
}

Hello, @@Fmilburn!

Thanks for you reply.

 

We have this code in file main.cpp in energia folder (\hardware\cc3200\cores\cc3200):

int main(void)
{
	setup();

	for (; {
		loop();
		if (serialEventRun) serialEventRun();
	}
}

and, we have this code in HardwareSerial.cpp in same folder:

void serialEventRun(void)
{
	if (Serial.available()) serialEvent();
	if (Serial1.available()) serialEvent1();
}

OK, put some debug print in serialEvent() for inChar to see if characters are being received.  In particular, make sure that a "/n" is being received so that the flag is set.  The serial monitor in Energia has a pull down tab lower right hand side that can be set to "No line ending" for example which would prevent this from working.

 

EDIT:  I don't have a working cc3200.  But for some reason, a baud rate of 1200 does not work reliably on the F5529 for me.  So you might try increasing that to 9600 or higher.

Hi @allefpablo

I have a similar problem accessing 2nd UART port. Have you been able to solve the problem?

THanks,

Sam
