- * 7. void OLED_Set_Pos(unsigned char x, unsigned char y) -- 设置显示坐标
- * 8. void OLED_Fill(unsigned char bmp_dat) -- 全屏显示(显示BMP图片时才会用到此功能)
- * 9. void OLED_CLS(void) -- 复位/清屏
- * 10. void OLED_Init(void) -- OLED屏初始化程序，此函数应在操作屏幕之前最先调用
- * 11. void OLED_P6x8Str(unsigned char x, y,unsigned char ch[]) -- 6x8点整，用于显示ASCII码的最小阵列，不太清晰
- * 12. void OLED_P8x16Str(unsigned char x, y,unsigned char ch[]) -- 8x16点整，用于显示ASCII码，非常清晰
- * 13.void OLED_P16x16Ch(unsigned char x, y, N) -- 16x16点整，用于显示汉字的最小阵列，可设置各种字体、加粗、倾斜、下划线等
- * 14.void Draw_BMP(unsigned char x0, y0,x1, y1,unsigned char BMP[]) -- 将128x64像素的BMP位图在取字软件中算出字表，然后复制到codetab中，此函数调用即可
