First, make sure you are selecting the correct driver
// define driver
#define PCF8833 // use for 6100
//#define SPFD54124B // use for 6085 and 6101
//#define ST7735R // use for JD-T1800 (1.8")
//#define HX8340B // use for BTL221722 (2.2" without touch)
//#define ILI9225B // 2.2" with touch
Then connect the pins as follows:
CS - P1.0
SCK - P1.5
DIO - P1.7
RESET - not using reset, tie it to any available pin on your LaunchPad and add a piece of code to reset your LCD before configuring. Alternatively, you can just tie it to Vcc.
You must also connect Vcc and GND.
