ShutDown OLED 1306

[error105]

Hi, there is any option to turn off OLED to save power?

There is no function to turn off the OLED. ssd1306WriteCmd() is public so you could try sendingSSD1306_DISPLAYOFF and SSD1306_DISPLAYON.

  oled.ssd1306WriteCmd(SSD1306_DISPLAYOFF);
  ...
  oled.ssd1306WriteCmd(SSD1306_DISPLAYON));

You can try it but I don't know if will save power or work properly.

I have developed a bit of code to avoid the OLED fading off when displaying the same text Here, I am just diming it, but you can also turn it off with the level of contrast

void setDisplayDIM()
{
        display.ssd1306WriteCmd(SSD1306_SETPRECHARGE);
        display.ssd1306WriteCmd(0);
        display.ssd1306WriteCmd(SSD1306_SETVCOMDETECT);
        display.ssd1306WriteCmd(0);
        display.ssd1306WriteCmd(SSD1306_SETCONTRAST);
        display.ssd1306WriteCmd(10);
}
void setDisplayNORMAL()
{
        display.ssd1306WriteCmd(SSD1306_SETPRECHARGE);
        display.ssd1306WriteCmd(0xF1);
        display.ssd1306WriteCmd(SSD1306_SETVCOMDETECT);
        display.ssd1306WriteCmd(0x20);
        display.ssd1306WriteCmd(SSD1306_SETCONTRAST);
        display.ssd1306WriteCmd(0xAF);
      }
