Do you know these wonderfully cheap SSD1306 based OLED displays with the crispy display? For a while now the NodeMCU Lua firmware for the ESP8266 supports them and has a rich feature set to draw lines, circles and even bitmaps. -- setup I2c and connect display function init_i2c_display() OLED Displays are great in many ways. They use very little power, are bright, easy to read with large viewing angle and have high resolution considering their small size. Since the SPI Bus is faster than I2C, this will make our display very responsive. Of course there's a tradeoff, the SPI Bus uses more...

Par contre, on dit que la durée de vie des écrans OLED est plus courte que celle des LCDs (l'image se dégrade avec le temps). L'écran Mon écran a une taille de 1,3 pouce (environ 3,5 cm X 1,8 cm) et une résolution de 128 X 64 pixels. Il est basé sur le contrôleur SH1106 et utilise le protocole I2C. L'image produite est blanche sur fond ...
After testing out printing output on LCD using ESP32 last week, this time we upgraded it a little by integrating the same thing with a weather sensor as an input. The weather sensor we used this ...

  • Bluetooth Low Energy (BLE) is a low power wireless technology used for connecting devices with each other. BLE operates in the 2.4 GHz ISM (Industrial, Scientific, and Medical) band, and is targeted towards applications that need to consume less power and may need to run on batteries for longer periods of time—months, and even years and it is…

OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays. Then we create an SSD1306_I2C object called oled. This object accepts the OLED width, height, and the I2C pins defined earlier.
