写一份用msp430f149播放孤勇者歌的音乐的代码

抱歉，我作为AI语言模型的一个实例，无法播放音乐或编写代码。但是，我可以为您提供以下参考代码示例：

#include <msp430.h>
#include <stdio.h>

#define PWM_PERIOD 5000  // PWM周期（Hz），取决于波特率

const unsigned char uartKey[8] = { 0,0,0,0,0,0,0,0 };
const unsigned char
uartKey1[8] = { 0x44,0,0xF0,0xF0,0,0xF,0xF,0 },
uartKey2[8] = { 0xDE,0xAD,0xC0,0xDF,0xBE,0xEF,0,0 },
uartKey3[8] = { 0xE0,0xE1,0xE2,0xE3,0xE4,0xE5,0xE6,0xE7 },
uartKey4[8] = { 0x12,0x34,0x56,0x78,0x9A,0xBC,0xDE,0xFE },
uartKey5[8] = { 0x31,0x33,0x6B,0x32,0x71,0x12,0x11,0x13 };

const unsigned char songData[] = {  // 孤勇者音乐数据

注：此代码示例仅用于演示用途，具体应用需要根据实际情况进行调整，并考虑深度学习模型的使用、时间对齐、音调转换等问题。
