關於控制芯片SH1106的說明：
12864OLED顯示屏是在某寶買的，以下圖片是某店鋪的說明：
內部電荷泵I2C接口：
SH1106既支持讀寫訪問。R/W位是從地址的一部分。在i2c總線上傳輸任何數據之前，應該先處理響應的設備。SH1106預留了兩個7位從地址(0111100和0111101)。通過將輸入SA0連接到邏輯0(VSS)或邏輯1 (VDD1)來設置從地址的最小有效位。i2c總線協議如圖7所示。該序列從I2C總線 主設備的開始條件開始，後面跟着從地址。具有相應地址的從設備應答，其他從機將忽略i2c總線傳輸。在確認之後，會有一個或多個命令來定義被尋址的從機的狀態。命令字由一個控制字節組成，它定義了Co和D/C (見note1)，加上一個數據字節(見圖7)。最後一個控制字節被標記爲一個清除的最重要的位，延續位Co。D /C位的狀態定義了數據字節是被解釋爲命令還是被解釋爲RAM數據。控制字節和數據字節被總線上相應的從設備接收。在最後一個控制字節之後，根據D /C位設置的不同，數據分爲顯示數據字節或命令數據字節。如果將D/C位設置爲’ 1 ‘，這些顯示字節將存儲在SRAM中，其地址由數據指針指定。數據指針自動更新，數據被寫入到預定的SH1106設備。如果最後一個控制字節的D /C位被設置爲’ 0 '，這些命令字節將被解碼，設備的設置將根據接收到的命令改變。
每個字節之後的確認只由被尋址的從設備發出。在傳輸結束時，i2c總線主機發出一個停止條件§。如果R/ W位在從地址中被設置爲1，芯片將根據在上次寫訪問期間發送的D /C位的從地址立即輸出數據。如果在一個字節之後沒有非應答，從設備停止向主機傳送數據。
命令表：
注意：不要使用任何其他命令，否則可能導致系統故障
手冊裏提供了初始化的演示程序：
以下部分可以參考程序自己寫：
這裏說一下，我買的模塊RST引腳已內置拉高。只有Vcc、Gnd、SDA、SCL這是個引腳。
下面說一下初始化命令的過程：
| 1.0xae | 顯示關 |
|---|---|
| 2.0x02 | 設置低列地址 |
| 3.0x10 | 設置高列地址 |
| 4.0x40 | 設置開始顯示行 |
| 5.0xb0 | 設置頁地址 |
| 6.0x81 | 設置對比度寄存器 |
| 0xff | 對比度數據（有0~255級對比度） |
| 7.0xa1 | 設置段重新映射（屏幕左右顛倒）） |
| 8.0xa6 | 設置正常顯示 |
| 9.0xa8 | 多路分配模式設置 |
| 0x3f | 多路複用率數據 |
| 10. 0xad | 內置升壓電荷泵設置 |
| 0x8b | 開啓內置電荷泵（驅動OLED需要比較高的電壓，我所買的模塊Vpp沒接出，所以要開啓內置的電荷泵)OLED工作電壓源：外部Vpp提供電壓6.4v-14.0V;內部Vpp發生器提供電壓6.4v-9.0V |
| 0x33 | 設置Vpp爲9v(設置泵電壓值Vpp(30H:6.4V；31H:7.4V；32H:8.0V；33H:9.0V) |
| 11.0xc8 | 設置COM輸出掃描方向（屏幕上下顛倒） |
| 12.0xd3 | 顯示偏移模式設置（SH1106僅支持垂直滾動）指定顯示開始行到COM0-63之一的映射 |
| 0x00 | 無偏移 |
| 13.0xd5 | 分頻比/振盪器頻率模式設置(屏幕刷新頻率) |
| 0x80 | 分頻比/振盪器頻率數據(0x80將時鐘設置爲100幀/秒) |
| 14.0xd9 | 無充電/預充電週期模式設置 |
| 0x1f | 無充電/預充電週期數據 |
| 15.0xda | COM引腳硬件配置模式設置,此命令用於設置通用信號墊配置。 |
| 0x12 | 參考文檔,順序:02H,替代:12H) |
| 16.0xdb | 取消級別模式設置 |
| 0x40 | VCOM=0.430VREF:00H, VCOM=0.770VREF:35H,VCOM=1*VREF:40H) |
| 17. 0xaf | 顯示開 |
注意:
本人買的的模塊RST是內部直接接高電平的，而官方給出的程序是有RST的，所以建議在開顯示之前先清屏一下，不然打開就是這個樣子。
如果你買的模塊是有RST引腳的，就不用清屏，開始先讓模塊拉低一會就可以了
清屏函數: void i2c_SH1106_CLS(void);
先說下使用這塊OLED出現的問題，文檔提供的開始顯示的列是從0x02開始的，顯示也是從0x02開始的，所以寫程序的時候開始都是從0x02開始，寫 字符串i2c_SH1106_P8x16Str(0, 6,"abcdtfgWTF1234 ")；和畫圖i2c_SH1106_DrawBMP(0,0,127,7,BMP);顯示正常，但寫i2c_SH1106_P6x8Str(0, 0,“0123456789”);這種小的字符串是，出現了亂碼，把開始的列改成0x01,問題解決，開始顯示的也是從第一個像素點開始的。我懷疑是我買的OLED有問題。
在發代碼之前先來幾張自己弄的XX圖片：
這兩張圖片都是128*64像素的，將格式轉成bmp的在取模就行了。
OLED顯示的圖片:（買的是藍屏的，效果不夠逼真，建議買白屏的）
i2c_master.h和i2c_master.c部分可以看我另一篇文檔：
