MSP432P401R: MSP 432 with 16X2 lcd

Also, in energia code in says connect LCD's clock pin but there is no clock pin on 16X2 lcd. It says connect reset pin and even thats not there on the lcd.

It's no surprise. Before using library, you you are advised to read it's documentation first: It says: Based on Arduino library for Dog character LCD's. Dog character LCD's are not based on HD44780 parallel I/O controller which most likely is used in your 16x2 LCD, they have SPI insterface instead.

So, how should I proceed towards coding 16X2 lcd with MSP432?

Definitely not by starting new thread regarding same "issue". Multiple threads does not increase your chances to get result, effect is rather opposite.

Get familiar with msp432 port I/O, take msp430 16x2 LCD example and modify it for msp432.

With all respect, I am pretty new to this environment

Don't worry. Everybody walked first steps like you are now. Not always there is "ready to consume" project around, sorry. Sometimes you have to learn first, then using small steps approach your target application/project. As already said - get familiar with I/O of msp432, compile and study blink LED example or similar, read msp430 16x2 LCD source code and datasheet of HD44780 to see how it's interfacing works.

You also have option to get msp430 Launchpad so you can play with msp430 16x2 LCD code to better understand how it works. Anyway if you have any other questions - feel free to ask.

Thank you for your kind words.

I figured out something, The simple code of Hello world display on MSP432 was not getting uploaded, on Windows 8. So, I tried it on my friends Windows 10 and then in got uploaded.

Though I still have a problem.

I connected the MSP432 with 16x2 LCD.
But both lines on 16x2 LCD show black boxes, no words at all.

Can you please help me on this.

I am using the following connections and code.

I copied the liquid crystal library from MSP430 to main library.

Connections-

01 - GND             GND
02 - VCC             +5V
03 - Contrast        GND 
04 - RS              Pin35 (P6_7) 
05 - R/W             GND 
06 - EN              Pin34 (P2_3) 
07 - DB0             GND 
08 - DB1             GND 
09 - DB2             GND 
10 - DB3             GND 
11 - DB4             Pin39 (P2_6) 
12 - DB5             Pin38 (P2_4) 
13 - DB6             Pin37 (P5_6) 
14 - DB7             Pin36 (P6_6) 
15 - BL+             +5V 
16 - BL-             GND 

Code -

#include <LiquidCrystal.h> 
LiquidCrystal lcd(35, 34, 39, 38, 37, 36); 
void setup() { 
  lcd.begin(16, 2); 
  lcd.print("hello, world!"); 
} 
void loop() { 
  lcd.noDisplay(); 
  delay(500); 
  lcd.display(); 
  delay(500);
