3. Using Peripherals

3.5.4. SPI Display Draw Line

This method prints a straight horizontal or vertical line on the Display. Unlike the "SPI Display String 6x8
XY" method, the start and end coordinates are given in pixel format. A line length can effectively be a
single dot on the screen.
bool SPIDisplayDrawLine
(
byte xs,
byte ys,
byte xe,
byte ye,
bool bg_color
);
Parameters:
byte xs
byte ys
byte xe
byte ye
bool bg_color
Return:

3.5.5. SPI Display Fill In Rectangle

This method fills in a rectangle on Display, overwriting everything within it. Can effectively be a single dot
on the screen.
bool SPIDisplayFillInRectangle
(
byte xs,
byte ys,
byte xe,
byte ye,
bool bg_color
);
Parameters:
byte xs
byte ys
byte xe
byte ye
bool bg_color
Return:
Start Point X-Coordinate (0 <= x < 102)
Start Point Y-Coordinate (0 <= x < 64)
End Point X-Coordinate (0 <= x < 102)
End Point Y-Coordinate (0 <= x < 64)
Background Color chosen for Display (0:clear, 1:black). Usually matches
the argument given to "SPI Display Clear" command.
If the operation was successful, the return value is true , otherwise it is
false .
Start Point X-Coordinate (0 <= x < 102)
Start Point Y-Coordinate (0 <= x < 64)
End Point X-Coordinate (0 <= x < 102)
End Point Y-Coordinate (0 <= x < 64)
Filling color (0:clear, 1:black)
If the operation was successful, the return value is true , otherwise it is
false .
