OLED汉字显示问题，OLED_ShowString(u8 x,u8 y,const u8 *p,u8 size)这个函数，第三个参数传入的是汉字的地址还不太明白

大佬们好，萌新提问：这是我创建的汉字库：

// 锄(0) 禾(1) 日(2) 当(3) 午(4) 汗(5) 滴(6) 禾(7) 下(8) 土(9) 谁(10) 之(11) 盘(12) 中(13) 餐(14) 粒(15)
// 粒(16) 皆(17) 辛(18) 苦(19)

};

当我们调用OLED_ShowString(u8 x,u8 y,const u8 *p,u8 size)这个函数时，第三个参数传入的是汉字的地址。例如：OLED_ShowString(0,0,"01234",16); ‘01234’分别是‘锄禾日当午’的地址。
第一到第十个汉字的地址依次是0-9，我发现从10开始，也就是库中的“谁”，地址变成了ASCLL中的“：”，之后依次按照ascll码表的顺序。
我想提问的是：如果汉字过多，超过了ascll的个数，那么之后的地址该如何确定呢？
