BLOX can be used to to display text and graphics on a couple different I2C and SPI based monochrome displays

I2C Based OLEDs (SSD1306/SH1106) are always a good choice. Easiest to wire, nice and bright, decent resolution and supports graphics

Initialize the display by configuring the type, size and address (for I2C) or pin assignment (for SPI or GPIO based displays)

Whenever you are ready to draw a new screen, you can clear the display

You can draw various elements, on their own or even better combine them together.

BLOX toolbox includes a Draw Custom Image block

Click the DRAW button and use your mouse to draw your own custom icons and graphics. You can change the size of the canvas as well for larger icons
