Firmware uses the Lua scripting language. h shows us that the fonts 6×10 and chikita are available here. That is why Str2 and Str5 need to be eight characters, even though "arduino" is only seven - the last position is automatically filled with a null character. Demo code for IIC OLED screen for LUA can be found at nodemcu github, /master/lua_examples/u8glib/ this folder, or click here to browse. GitHub Gist: instantly share code, notes, and snippets. Thus I decided to DIY an simple indoor carbon dioxide detector with Arduino. First, this code starts with declaring a library we will be using, the U8glib library, which helps us to operate the OLED being used. Online Image Converter Program. Arduino Due and OLED Display using U8GLIB library in SPI mode- Getting started Getting started with 0. It sacrifices precision and instead it is way faster than floating-point implementations. Ein 0,96 Zoll OLED Display I²C mit 128×64 Pixel und ein Arduino; Kurz vorgestellt: GPS-Modul (GY-GPS6MV2) mit NEO-6M von u-blox. Most libraries have a bad result, but the u8glib is almost working, only the characters are shifted some to the left. This project uses an HC-SR04 Ultrasonic Transmitter/Receiver to measure a distance up to about 100 cm or 3 feet. Through NodeMcu, you can build up IoT(Internet of Things) BY YOUR OWN HAND.
