# 根据LCD商家给出的相应的初始化示例来填写
# 第一行：2, 0, 120,		2表示sleep命令,中间恒为0,120表示sleep的毫秒数。收到此行数据,LCD将sleep 120ms
# 第二行：0, 0, 0x11,		0表示写入寄存器地址命令,中间数字表示后续需要写入的DATA长度，0表示没有要写入的数据,0x11是寄存器地址
# 第三行：0, 1, 0x36,		0表示写入寄存器地址命令,中间数字表示后续需要写入的DATA长度，1表示要写入一字节数据,0x36是寄存器地址
# 第四行：1, 1, 0x00,		1表示写入数据命令,中间数字表示写入的数据长度,0x00是数据
# 后面按照前四行的格式将初始化示例填入即可
