使用for循環把地址以此改變就行了

void Bmp_Right_Disp(unsigned char page,unsigned char column, unsigned char code *Bmp)
這個函數的各個參數，你明白是做什么用的嗎？
unsigned char page是什么？
unsigned char column又是什么？
搞明白了你就會你要的動作了。

弄清楚void Bmp_Right_Disp(unsigned char page,unsigned char column, unsigned char code *Bmp)
里各個參數的指代即可

void Bmp_Right_Disp(unsigned char page,unsigned char column, unsigned char code *Bmp)函數里
unsigned char page 相當于行
unsigned char column相當于列
你都知道將 page 變成 0，2，4，6 將內容顯示在屏對應的行上，那是不是可以通過改變column將內容顯示在不同的列上，column動態變化起來內容是不是就移動顯示了。
人家不是藏著，是讓你思考起來，授人以魚不如授人以漁。要想在技術的路上走下去，學會自我學習才是最重要的。

通過循環結構里頭按順序1,先調用函數寫一個清屏幕的程序2，每個字符對應的顯示點坐標向前+2個像素3，判斷是否最后一個文字是否滾動出屏幕4，如果3完成則接出第一個字符，否則繼續顯示下載一個字符
