Coordinates
The OLED screen has a screen resolution of 128 pixel wide by 64 high.
The OLED blocks "x" and "y" values reference the screen resolution with origin (0,0).
The origin (0, 0) is on the top left of the screen (in reference to image below).
Blocks

This block displays a message on the OLED screen. The bottom left corner of the text is aligned to the "x" and y" input. Each character (default) is about 10 pixels tall.
- x - "x" position of the message.
- y - "y" position of the message.
- message - message to display.
OLED - Draw Line
This block draws a line on the OLED screen. With the starting point as (x0, y0) and the ending point as (x1, y1). The line width is about 1 pixel.
- line / rectangle - draw either a line or rectangle. Leave on line to draw a line.
- Start point - x0, y0
- End point - x1, y1
OLED - Draw Rectangle
This block draws a rectangle on the OLED screen. With the top left corner point as (x0, y0) and the bottom right corner point as (x1, y1). The line width is about 1 pixel.
 Note: This block uses the OLED - Draw Line block, but configured for a rectangle. |
- line / rectangle - draw either a line or rectangle. Change to rectangle to draw a rectangle.
- Top left corner - x0, y0
- Bottom right corner - x1, y1
OLED - Draw Circle
This block draws a circle on the OLED screen. With the center of the on the "x" and "y" inputs with a radius of "r".
- center of circle - x, y
- r - radius of the circle.
OLED - Clear
