Six colors

What this example shows

Inkplate 7SPECTRA has one display mode: every pixel takes one of six colors. This example fills the screen with six vertical bars, one per color, so you can see the whole palette at once.

Constant	Color
INKPLATE_BLACK	Black
INKPLATE_WHITE	White
INKPLATE_YELLOW	Yellow
INKPLATE_RED	Red
INKPLATE_BLUE	Blue
INKPLATE_GREEN	Green

Functions used

Inkplate()returns None

Creates the Inkplate object. Inkplate 7SPECTRA has a single six-color mode, so the constructor takes no mode argument.

ReturnsConstructor; no return value.

display.begin()returns void

Initializes the library, the peripherals and the frame buffer. Call it once in setup(); later calls are ignored.

ReturnsNothing.

display.clearDisplay()returns void

Fills the frame buffer with white. It does not change the panel; call display() afterwards for that.

ReturnsNothing.

display.fillRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t color)returns void

Draws a filled rectangle into the frame buffer. From the Adafruit GFX class the library builds on.

ReturnsNothing.

Parameters

Type	Name	Description
int16_t	x	Left edge in pixels.
int16_t	y	Top edge in pixels.
int16_t	w	Width in pixels.
int16_t	h	Height in pixels.
uint16_t	color	One of the six color constants.

display.display(bool _leaveOn = 0)returns void

Sends the whole frame buffer to the panel and refreshes it (a full update).

ReturnsNothing.

Parameters

Type	Name	Description
bool	_leaveOn	If true, the panel supply stays on after the update. Defaults to 0.

What to expect

The screen shows six vertical bars of equal width, from left to right: black, white, yellow, red, blue and green. The sketch prints nothing to the Serial Monitor.
