Tiny Function Plotter using ATtiny85

David Johnson-Davies build a OLED display function plotter based on ATtiny85 microcontroller. He writes:

This project describes a simple routine for plotting a function on a 128×64 I2C OLED graphics display. Unlike most Arduino graphics libraries this routine doesn’t require a RAM buffer, and so will work on any processor down to an ATtiny85:

The routine will work on monochrome 128×64 I2C OLED displays based on either the SSD1306 driver, such as the display available from Adafruit, or the SH1106 driver, used in displays available from Chinese suppliers.
