c - 二维阵列的一部分的无限循环工作

问题描述

当我在 Xcode 中编译它printf并为每个字母的破折号和点运行语句时，我的代码可以工作。但是，当我将代码放入 TI Code Composer Studio 时，代码可以正常工作，但它只会在我的微控制器上闪烁“Go Knights”的第一个字母“G”。

我知道它与“while”循环有关，但我不确定它是什么。我已经移动了所有东西，打开/关闭了闪光灯，关闭了我的计数器，将我的变量从全局变量更改为局部变量，检查语法是否有任何缺失，删除了 if 语句==-1，但没有任何效果

#include <msp430g2553.h> 
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>

unsigned int i = 0;
unsigned int j=0;
int row = 0;

void main(void)`
{

char str [] = "Go Knights";
int morse_array [36][6] = { //array for A-Z, 0-9 in morse code
    {0,1,-1},      //'.' = 0 and '-' = 1 and all else = -1
    {1,0,0,0,-1},
    {1,0,1,0,-1},
