Not Working??!! #226

Hi guys, just installed the library and I am experimenting a few issues that does not able the Oled to run. I have a 0.96" 128x64 SPI Oled screen conected to a Wemos D1 mini. The pins that I am using are as below;

// Initialize the OLED display using SPI // D5 -> CLK // D7 -> MOSI (DOUT) // D0 -> RES // D2 -> DC // D8 -> CS // SSD1306Spi display(D0, D2, D8);

I have installed this library into my: Documents\Arduino\libraries\esp8266_oled_ssd1306

Also installed the Adafruit_GFX library: Documents\Arduino\libraries\Adafruit_GFX

As I am using the SPI board, I have unmmuted the code as explained in the instructuons, see below;

// Include the correct display library // For a connection via I2C using Wire include //#include // Only needed for Arduino 1.6.5 and earlier //#include "SSD1306Wire.h" // legacy include: #include "SSD1306.h" // or #include "SH1106Wire.h", legacy include: #include "SH1106.h" // For a connection via I2C using brzo_i2c (must be installed) include // #include // Only needed for Arduino 1.6.5 and earlier // #include "SSD1306Brzo.h" // #include "SH1106Brzo.h" // For a connection via SPI include

include // Only needed for Arduino 1.6.5 and earlier (UNMMUTED)

include "SSD1306Spi.h" (UNMMUTED)

// #include "SH1106SPi.h"

// Use the corresponding display class:

// Initialize the OLED display using SPI // D5 -> CLK // D7 -> MOSI (DOUT) // D0 -> RES // D2 -> DC // D8 -> CS SSD1306Spi display(D0, D2, D8); (UNMMUTED) // or // SH1106Spi display(D0, D2);

// Initialize the OLED display using brzo_i2c // D3 -> SDA // D5 -> SCL // SSD1306Brzo display(0x3c, D3, D5); // or // SH1106Brzo display(0x3c, D3, D5);

// Initialize the OLED display using Wire library SSD1306Wire display(0x3c, D3, D5); // SH1106 display(0x3c, D3, D5);

When it comes to compiling the latest line shown, "SSD1306Wire" it says does not name a type. Then UNMMUTED the line on the top of the code...

include "SSD1306Wire.h" // legacy include: #include "SSD1306.h" (UNMMUTED)

The file now compiles fine and I uploaded to the Wemos mini but the Oled does not run.

Not sure what makes it not to run, as I have been playing with libraries directories and everything that I could thought but couldn't make it to run. BTW I am using the Drawing Demo.

Thanks

I'd like to say I'm having the same problem. The display works fine in SPI mode, confirmed with adafruit lib, although I'm using a nodemcu ESP8266.

`// If using software SPI (the default case):

define OLED_MOSI D7 //D1 NodeMcu D7

define OLED_CLK D5 //D0 NodeMcu D5

define OLED_DC D4

define OLED_CS D8

define OLED_RESET D6

Adafruit_SSD1306 display(OLED_MOSI, OLED_CLK, OLED_DC, OLED_RESET, OLED_CS);`

I've tried a couple of the examples and fixed the pins, but I can't get anything with the following //#include "SSD1306Wire.h"

include

include "SSD1306Spi.h"

SSD1306Spi display(D6, D4, D8); //RESET, DC, CS //SSD1306Wire display(0x3c, D3, D5);

Change 0x3c to 0x3d. The code was written to run on nodemcu, not wemos. Change Pins to D2 and D1 - http://automatedhome.party/wp-content/uploads/2017/04/WemosOLED.png

The setup should be fine now, but it is does not work for me. Does it for you?
