    John, well written and explained. The 64:1 saving by using a global variable use for the loop is genius.

  • I2C OLED Display Using Arduino/NodeMCU over 1 year ago

    Great In depth instructable. I had project that used a char based 4x20 I2C display. Just for the fun of it I connected a .96 SSD1306 graphics display. Some interesting issues. Once you write characters to the screen how do you turn them off. I found the colour field 1 On ,0 off would accomplish this. Once I wrapped my head around the graphics bit maps, it was very easy to create animated bar graphs and text prompts. One trick I used to erase a line of text( Ada-fruit lib) , was display a rectangle, Char height, length of the line, and display it in black (0) to quickly and simply erase the line.
