Energia COM port help

[abecedarian 330]

Energia says the only COM port I have (COM8) is not found, and suggests using a COM port (COM3) ... which I do not have.

I've been dealing with this since late last night.

 

Code I upload to the G2LP doesn't work properly either.

This:

// Crankshaft / camshaft rotation simulation
// Engine is V-twin with cylinders at 80 degrees opposed
// Connecting rods share a common crankshaft journal
// Code is based on a full camshaft cycle (720 degrees rotation)
// and when spark plugs should fire. Actual ignition advance is
// not factored in yet since advance would move right and left cylinders'
// 'trigger' points accordingly and that would cause the right
// cylinder to be less than zero. So until I work in that logic,
// as of now, both cylinders fire spark plugs with 0 degrees ignition advance.
// This means right spark plug would fire when the cam trigger occurs and
// left spark plug would fire 440 degrees later:
// Left cylinder fires 360 + 80 = 440;
// right cylinder would fire 280 degrees afterwards:
// 440 + 280 = 720 (or 0 if you prefer). 
//
// Target in Energia IDE is MSP430G2553 @ 16MHz
//


const uint16_t t1 = 0; // right cylinder baseline spark
const uint16_t t2 = 440; // left cylinder baseline spark relative right cylinder
const uint8_t cam = 0; // camshaft trigger relative right cylinder TDC

const uint8_t AMBER_LED = 5; // LP pin indicating camshaft trigger signal occurrence
// I am using existing RED_LED, GREEN_LED for right and left cylinder TDC indicators


uint16_t degree = 0; // counter for crankshaft rotation in degrees

void setup()
{
pinMode(RED_LED, OUTPUT);
pinMode(GREEN_LED,OUTPUT);
pinMode(AMBER_LED, OUTPUT);

// debug messages:
Serial.begin(9600);
}

void loop()
{
for (degree = 0; degree < 720; degree++) {
Serial.print(degree); // debug message
Serial.print(" ");

// Camshaft:
digitalWrite(AMBER_LED,(degree >= cam && degree < cam+100));
Serial.println((degree >= cam && degree < cam+100)); // debug message

// Right cylinder:
digitalWrite(RED_LED,(degree >= t1 && degree < t1+50));
Serial.print((degree >= t1 && degree < t1+50)); // debug message
Serial.print(" ");

// Left cylinder:
digitalWrite(GREEN_LED,(degree >= t2 && degree < t2+50));
Serial.print((degree >= t2 && degree < t2+50)); // debug message
Serial.print(" ");

// delay(5);
}
}

Blinks an LED every 4 seconds or so, but should be blinking them faster than I can detect.

When I try to open the terminal window / serial monitor, I get:

Well I guess... never mind.

Rebooted twice and now it seems okay.

 

I'm at a loss.

I've found that I have COM port issues if I have the serial monitor open when I plug a launchpad in.

That's guaranteed failure, like the above.

The solution for me is to unplug the launchpad, close the serial monitor, and re-plug the launchpad.

 

That's the only similar thing I've run into.
