The OLED module looks absolutely the same, has the same pinout (SPI connection) and same resolution (128x160) Despite their similarities For the ST7789 controller, I have a SetAddressWindow(int x_start, int y_start, int x_end, int y_end) which requires both the initial coordinate and the tile width/height, whereas the u8g2 library seems to want to set only the initial coordinate. A graphics library with support for many different monochrome displays. Using U8g2 font in Arduino_GFX simply include U8g2lib. I did this in the above mentioned setup tutorial. Jan 26, 2020 · Hello, I'm trying to turn on my OLED Waveshare 128*128 SSD1327 screen using i2c communication and u8g2 library with the NRF51 DK development kit but unfortunately my module doesn't turn on. So I copied the relevant files and made them a functional component Hi all, I have a question about the update procedure of the u8g2 library. I'm still thinking about m2tk. I tested many ways to align words (Especially UTF-8 words). This is an attempt to speed up UI development for Arduino projects using the U8G2 library (https://github U8glib library for monochrome displays, version 2 - U8g2-Library/ChangeLog at master · BinaryLeo/U8g2-Library E-paper displays are getting more and more popular for battery powered applications. gnxalrxzqzvojyzxdgakcyflxncpeqozhwrtkzwruqecumr
