When adding the original LCD library by @agaelema, adopt the "lcd16x2_msp43x.h" to specific board:
/***************************************************************************************
* LCD PINS DEFINITION - will define PORT and PINS used by LCD
***************************************************************************************/
#define _EN_PORT 4 // default EN port - P1
#define _EN_PIN 2 // default EN pin - P1.6
#define _RS_PORT 4 // default RS port - P1
#define _RS_PIN 0 // default RS pin - P1.7
#define _LCD_4BIT_PORT 4 // port used to data
#define _LCD_DATA_BASE 4 // first low pin of 4 bit interface
#define _LCD_4BIT_HIGH 0x0F // 4 bits in high mode
- Get stuff connected
