Hello,
I need some guidance on Programming MSP-EXP430G2 Launchpad using Energia on Linux OS.
This is the first time I am using energia.
The main objective for using energia is to be able to program/debug MSP-EXP430G2 Launchpad in Linux environment (as CCS 6.0 does not support MSP-EXP430G2 Launchpad on linux)
Guidance needed for:
Kindly guide me on how can I get things working in usermode.
Specially, I would like to be able to
1. pass any argument while my code is running in the device (equivalent to scanf/getc/getchar in C programming).
2. Print information while my code is running in the device (equivalent to printf/putc/putchar in C programming).
System Information:
Launchpad: MS-EXP430G2 Rev 1.5

Serial Monitor window shows up without any error
Following code does not show any output in Serial Monitor window or in status window of energia.
void setup () {

Serial.begin(9600);
// Initialize the digital pin as output.
// Pin 2:14 leds have connected:

}
void loop () {
digitalWrite (14, HIGH); // Led on

digitalWrite (2, HIGH); // Led on
