Tiny Graphics Library for ATtiny85 and SH1106 OLED Display
David Johnson-Davies published another great tutorial on how to use the Tiny Graphics Library to plot the outside temperature over 24 hours on a 128×64 OLED display using an ATtiny85.
This small graphics library provides point, line, and character plotting commands for use with an I2C 128×64 OLED display on an ATtiny85.
It supports processors with limited RAM by avoiding the need for a display buffer, and works with I2C OLED displays based on the SH1106 driver chip. These are available for a few dollars from a number of Chinese suppliers.
To demonstrate the graphics library I’ve written a simple application to measure the temperature every 15 minutes over a 24-hour period and display it as a live chart.
