Hi! Welcome to my portfolio

Integrating LVGL embedded graphics library with SSD1306 OLED display on ESP32. Source code Project goal Get LVGL working on a 128x64 monochrome OLED display connected to ESP32 with I2C. Quick googling resulted only in outdated libraries. This implementation uses the latest libraries to ensure future proofing. Main challenge LVGL outputs pixels in a linear framebuffer format but the display uses page addressing where the screen is divided into 8 horizontal pages of 128x8 pixels. Required implementing a custom flush callback to convert between these formats. ...

Using a VM was not ideal on my machine. It introduces a lot of overhead and requires a lot of disk space which my machine simply does not have. Installing directly on the host was also out of question as the project required a lot of outdated dependencies. ...
