SSD1306 OLED LCD Library
Although there are already many examples and fine libraries readily available, most of them are using a buffer, meaning all the drawing operations are saved to a memory array and them dumped to the LCD as one complete frame. This has certain advantages that I would normally go for, but it also uses a lot of memory, a no go for small microcontrollers. This is why I wanted to write a library that will directly write to the LCD hardware instead of using a buffer. It's a bit slower but it saves considerable memory!
Simple AVR Bootloader tutorial
I've used AVR microcontrollers both for hobbies and work projects. These versatile microcontrollers ran the code I programmed them with, but once the final device was shipped, it was hard…
