Question: I am working on a project using the LGM 1 2 6 4 1 BS 1 R in Proteus, and I am building it in

I am working on a project using the LGM12641BS1R in Proteus, and I am building it in real life with a 12864h-2k graphic LCD on a breadboard. However, I am not able to see any images or menu screens on the LCD.
The 12864h-2k graphic LCD I am using has an RS pin, but in the Proteus simulation, the LGM12641BS1R LCD I am using has a DI pin in its pinout. In the CCS C code, if I change the pin definition from
#define GLCD_DI PIN_B5 to #define GLCD_RS PIN_B5, the LCD does not work in Proteus. Could this be the cause of the issue? If so, how would you recommend I solve this problem? (LGM12641BS1R is an 18-pin LCD, 12864h-2k is a 20-pin graphic LCD).
