SSD1306 128x64 OLED 【三】

日期：

在不使用Adafruit的Library來試著點SSD1306


一．產生圖形資料

把上圖logo(128x64 bits)轉換成Array data

使用這個網站來轉換 https://javl.github.io/image2cpp/


1. Select Image，匯入圖形檔


2. Image Settings，圖形設定 (沒有要修改的設定)


3. 確認圖形有正常顯示

4. Code output format，選擇 Arduino code, single bitmap

5. Draw mode，選擇 Vertical - 1 bit per pixel

6. 點擊 Generate code產生出陣列資料，然後按 Copy output複製array data


二．Arduino IDE

把下列程式直接複製貼上你的Arduino IDE (上面的logo陣列已經在 NaN[] 裡面)


#include "Wire.h"

沒意外的話你已經能看到圖形出現在你的OLED

；但意外還是發生了，圖形並不正確



上列程式的初始設定是照datasheet最後的流程圖寫入的，視乎有些地方需要調整

硬體Set COM Pins Hardware Configuratio (DAh)寫入值由0x02h改為12h

  • A[4]=0b, Sequential COM pin configuration
  • A[4]=1b(RESET), Alternative COM pin configuration
  • A[5]=0b(RESET), Disable COM Left/Right remap
  • A[5]=1b, Enable COM Left/Right remap
  // Set COM Pins
  Wire.beginTransmission(0x3C);
  Wire.write(0x00);
  Wire.write(0xDA);
  Wire.write(0x12);
  Wire.endTransmission();
  delay(10);

修改後的結果如下



圖形180度翻轉 (改變COM0到COMn的寫入順序)

Set COM Output Scan Direction寫入值由0xC0h改為C8h

  • C0h, X[3]=0b: normal mode (RESET) Scan from COM0 to COM[N –1]
  • C8h, X[3]=1b: remapped mode. Scan from COM[N-1] to COM0

    • Where N is the Multiplex ratio.

  // Set COM Output Scan Direction
  Wire.beginTransmission(0x3C);
  Wire.write(0x00);
  Wire.write(0xC8);
  Wire.endTransmission();
  delay(10);

圖形是轉向了；可卻呈現鏡向的情況


Set Segment Re-map寫入值由A0h改為A1h

  • A0h, X[0]=0b: column address 0 is mapped to SEG0 (RESET)
  • A1h, X[0]=1b: column address 127 is mapped to SEG0
  // Set Segment re-map
  Wire.beginTransmission(0x3C);
  Wire.write(0x00);
  Wire.write(0xA1);
  Wire.endTransmission();
  delay(10);

結果
