Compiler/MSP432P401R: print 32 bits number on terminal

Tool/software: TI C/C++ Compiler

Hi!

I'm trying to print 32 bits number (input) to the terminal. However, it didn't print anything (or maybe I do not know where to look for the output). I got warnings when I run the project. Below is the warning and I include the lines.

"../project_zero.c", line 1169: warning #225-D: function "printf" declared implicitly

case LED_CHAR1:
        switch (PROFILE_ID_CHARTYPE(charID))
        {
        case PROFILE_VALUE:
            //32 bits
            LEDService_getParameter(charID, &value);
            printf("%d\n", value);
            break;

        default:
            break;
        }
        break;
       

"../Profile/led_service.c", line 501: warning #70-D: integer conversion resulted in truncation ".

 case LED_CHAR1:
        switch (PROFILE_ID_CHARTYPE(charID))
        {
        case PROFILE_VALUE:
            if (len == sizeof(ls_LED0OnOFFVal))
            {
                memcpy((uint8_t *)&ls_LED032BitsVal, pData, sizeof(ls_LED032BitsVal));
                status = SNP_SUCCESS;
                notifyApp = LS_LED0_32BITS_UUID;
            }
            break;

./Profile/led_service.c", line 535: warning #169-D: argument of type "uint8_t" is incompatible with parameter of type "void *__restrict__" "..

/Profile/led_service.c", line 537: warning #70-D: integer conversion resulted in truncation

 case LED_CHAR3:
        switch (PROFILE_ID_CHARTYPE(charID))
        {
        case PROFILE_VALUE:
            if (len == sizeof(ls_LED0SwitchVal))
            {  
                memcpy(ls_LED0SwitchVal, pData, sizeof(ls_LED0SwitchVal));
                status = SNP_SUCCESS;
                notifyApp = LS_LED0_HA_INTENSTITY_UUID;
            }
            break;
