* OLED屏測(cè)試程序

* 調(diào)用方法：
* LCD_Init();  // OLED 初始化
* LCD_Fill(0x00);  // 全屏填充 0x00
* LCD_GBK16(0, 2, "1.鋤禾日當(dāng)午，\r2.汗滴禾下土。\r3.誰(shuí)知盤中餐，");
* LCD_P6x8Str (0,4,"OLED"); // 顯示6*8  字符串
* = HowMuchWidth(Num);// 獲取某數(shù)有幾位
* LCD_IntNum(x, y, HowMuchWidth(v), v); // 顯示數(shù)字
* LCD_16Pic(unsigned char x,unsigned char y,unsigned char width,unsigned char dat[]);//16像素高度圖片
* LCD_8Pic(unsigned char x,unsigned char y,unsigned char width,unsigned char ch[]);//8像素高度圖片
* LCD_AllPic(unsigned char dat[]);//全局圖像顯示
*
*
* 說(shuō)明：圖像取模：縱向取模，字節(jié)倒序
