5.2 Graphics Commands
toward the right) and Y values go from 0 to 63 (increasing toward the bottom).
5.2.1 Set Drawing Colour (254 99 [color])
color passed as a parameter. The parameter [color] is the value of the color where white 0 Hex, and black is
255 Hex.
5.2.2 Draw Line (254 108 [x1][y1][x2][y2])
be drawn from any part of the display to any other part, but may be important to note that the line may
interpolate differently right to left, or left to right. This means that a line drawn in white from right to left
may not fully erase the same line drawn in black from left to right.
5.2.3 Continue Line (254 101 [x][y])
command uses the global drawing color so the “Set drawing color” command should be used before the first
line segment if required.
5.2.4 Put Pixel (254 112 [x][y])
requests fast enough to keep up with a steady stream at 115 kbaud, so flow control is not required.
5.2.5 Draw Outline Rectangle (254 114 [color][x1][y1][x2][y2])
corner is specified by (x1,y1) and the bottom right corner by (x2,y2).
