OLED is the organic Light Emitting Diode. For the OLED has the good feature of self-luminous, no needing back-light,high contrast ratio, thin,wide visual angle, rapid reaction speed, can use at flexural board, wide temperature range, structure and sample processing manufacture ect , which is regarded as the next generation flat surface display new applied technology. LCD need back light, but OLED do not need, for it is self-luminous. So the same display, OLED is much better. To the recent technology, OLED size is hard to large scale, but the resolution ratio can improve. This screen can use the drive IC SSD1306, every page of SSD1306 include 128 byte, total 8 pages, the matrix array is just exactly 128*64.

Step 1:

GNDVCC:positive(3V~5.5V)DO:SPI clock line pinDI:SPI data line pinRES:reset pinDC:data and order pinCS:chip selection pin

Step 2:

1 x pcDuino3

1 x OLED

Jumper lines

1 x board

Step 3:

Step 4:

1. wire according to the following instruction:

OLED GND –> pcDuino GND OLED VCC –> pcDuino 3.3V OLED D0 –> pcDuino D10 OLED DI –> pcDuino D9 OLED RES –> pcDuino D13 OLED D/C –> pcDuino D11 OLED CS –> pcDuino D12

2. download the test code in the attachment, then open in the Arduino IDE, click and compile:
3. Run effect as the following picture: Display the character

Display the round dot:

Display segment:

Step 5: Download and Attachment

Test Code: spi_olde_test

SSD1306 Datasheet :SSD1306
