displayio – Native helpers for driving displays¶
The displayio module contains classes to manage display output
including synchronizing with refresh rates and partial updating.
Available on these boards
- displayio.release_displays() None¶
Releases any actively used displays so their busses and pins can be used again. This will also release the builtin display on boards that have one. You will need to reinitialize it yourself afterwards. This may take seconds to complete if an active EPaperDisplay is refreshing.
Use this once in your code.py if you initialize a display. Place it right before the initialization so the display is active as long as possible.
- class displayio.Colorspace¶
The colorspace for a
ColorConverterto operate in- RGB888 :Colorspace¶
The standard 24-bit colorspace. Bits 0-7 are blue, 8-15 are green, and 16-24 are red. (0xRRGGBB)
- RGB565 :Colorspace¶
The standard 16-bit colorspace. Bits 0-4 are blue, bits 5-10 are green, and 11-15 are red (0bRRRRRGGGGGGBBBBB)
- RGB565_SWAPPED :Colorspace¶
The swapped 16-bit colorspace. First, the high and low 8 bits of the number are swapped, then they are interpreted as for RGB565
- RGB555 :Colorspace¶
The standard 15-bit colorspace. Bits 0-4 are blue, bits 5-9 are green, and 11-14 are red. The top bit is ignored. (0bxRRRRRGGGGGBBBBB)
- RGB555_SWAPPED :Colorspace¶
The swapped 15-bit colorspace. First, the high and low 8 bits of the number are swapped, then they are interpreted as for RGB555
- class displayio.Bitmap(width: int, height: int, value_count: int)¶
Stores values of a certain size in a 2D array
Bitmaps can be treated as read-only buffers. If the number of bits in a pixel is 8, 16, or 32; and the number of bytes per row is a multiple of 4, then the resulting memoryview will correspond directly with the bitmap’s contents. Otherwise, the bitmap data is packed into the memoryview with unspecified padding.
A Bitmap can be treated as a buffer, allowing its content to be viewed and modified using e.g., with
ulab.numpy.frombuffer, but thedisplayio.Bitmap.dirtymethod must be used to inform displayio when a bitmap was modified through the buffer interface.bitmaptools.arrayblitcan also be useful to move data efficiently into a Bitmap.Create a Bitmap object with the given fixed size. Each pixel stores a value that is used to index into a corresponding palette. This enables differently colored sprites to share the underlying Bitmap. value_count is used to minimize the memory used to store the Bitmap.
- Paramètres:
- width :int¶
Width of the bitmap. (read only)
- height :int¶
Height of the bitmap. (read only)
- __getitem__(index: Tuple[int, int] | int) int¶
Returns the value at the given index. The index can either be an x,y tuple or an int equal to
y * width + x.This allows you to:
print(bitmap[0,1])
- __setitem__(index: Tuple[int, int] | int, value: int) None¶
Sets the value at the given index. The index can either be an x,y tuple or an int equal to
y * width + x.This allows you to:
bitmap[0,1] = 3
- blit(x: int, y: int, source_bitmap: Bitmap, *, x1: int, y1: int, x2: int, y2: int, skip_index: int) None¶
- Inserts the source_bitmap region defined by rectangular boundaries
(x1,y1) and (x2,y2) into the bitmap at the specified (x,y) location.
- Paramètres:
x (int) – Horizontal pixel location in bitmap where source_bitmap upper-left corner will be placed
y (int) – Vertical pixel location in bitmap where source_bitmap upper-left corner will be placed
source_bitmap (bitmap) – Source bitmap that contains the graphical region to be copied
x1 (int) – Minimum x-value for rectangular bounding box to be copied from the source bitmap
y1 (int) – Minimum y-value for rectangular bounding box to be copied from the source bitmap
x2 (int) – Maximum x-value (exclusive) for rectangular bounding box to be copied from the source bitmap
y2 (int) – Maximum y-value (exclusive) for rectangular bounding box to be copied from the source bitmap
skip_index (int) – bitmap palette index in the source that will not be copied, set to None to copy all pixels
- dirty(x1: int = 0, y1: int = 0, x2: int = -1, y2: int = -1) None¶
Inform displayio of bitmap updates done via the buffer protocol.
- Paramètres:
x1 (int) – Minimum x-value for rectangular bounding box to be considered as modified
y1 (int) – Minimum y-value for rectangular bounding box to be considered as modified
x2 (int) – Maximum x-value (exclusive) for rectangular bounding box to be considered as modified
y2 (int) – Maximum y-value (exclusive) for rectangular bounding box to be considered as modified
If x1 or y1 are not specified, they are taken as 0. If x2 or y2 are not specified, or are given as -1, they are taken as the width and height of the image. Thus, calling dirty() with the default arguments treats the whole bitmap as modified.
When a bitmap is modified through the buffer protocol, the display will not be properly updated unless the bitmap is notified of the « dirty rectangle » that encloses all modified pixels.
- class displayio.ColorConverter(*, input_colorspace: Colorspace = Colorspace.RGB888, dither: bool = False)¶
Converts one color format to another.
Create a ColorConverter object to convert color formats.

- class displayio.Display(display_bus: _DisplayBus, init_sequence: _typing.ReadableBuffer, *, width: int, height: int, colstart: int = 0, rowstart: int = 0, rotation: int = 0, color_depth: int = 16, grayscale: bool = False, pixels_in_byte_share_row: bool = True, bytes_per_cell: int = 1, reverse_pixels_in_byte: bool = False, set_column_command: int = 42, set_row_command: int = 43, write_ram_command: int = 44, backlight_pin: microcontroller.Pin | None = None, brightness_command: int | None = None, brightness: float = 1.0, auto_brightness: bool = False, single_byte_bounds: bool = False, data_as_commands: bool = False, auto_refresh: bool = True, native_frames_per_second: int = 60, backlight_on_high: bool = True, SH1107_addressing: bool = False)¶
Manage updating a display over a display bus
This initializes a display and connects it into CircuitPython. Unlike other objects in CircuitPython, Display objects live until
displayio.release_displays()is called. This is done so that CircuitPython can use the display itself.Most people should not use this class directly. Use a specific display driver instead that will contain the initialization sequence at minimum.
Create a Display object on the given display bus (
FourWire,ParallelBusorI2CDisplay).The
init_sequenceis bitpacked to minimize the ram impact. Every command begins with a command byte followed by a byte to determine the parameter count and delay. When the top bit of the second byte is 1 (0x80), a delay will occur after the command parameters are sent. The remaining 7 bits are the parameter count excluding any delay byte. The bytes following are the parameters. When the delay bit is set, a single byte after the parameters specifies the delay duration in milliseconds. The value 0xff will lead to an extra long 500 ms delay instead of 255 ms. The next byte will begin a new command definition. Here is an example:init_sequence = (b"\xe1\x0f\x00\x0E\x14\x03\x11\x07\x31\xC1\x48\x08\x0F\x0C\x31\x36\x0F" # Set Gamma b"\x11\x80\x78"# Exit Sleep then delay 0x78 (120ms) b"\x29\x81\xaa\x78"# Display on then delay 0x78 (120ms) ) display = displayio.Display(display_bus, init_sequence, width=320, height=240)
The first command is 0xe1 with 15 (0xf) parameters following. The second is 0x11 with 0 parameters and a 120ms (0x78) delay. The third command is 0x29 with one parameter 0xaa and a 120ms delay (0x78). Multiple byte literals (b » ») are merged together on load. The parens are needed to allow byte literals on subsequent lines.
The initialization sequence should always leave the display memory access inline with the scan of the display to minimize tearing artifacts.

The default
minimum_frames_per_secondof 0 disables this behavior.When auto_refresh is off, and
target_frames_per_secondisNonethis will update the display immediately.When auto_refresh is on, updates the display immediately. (The display will also update without calls to this.)

start_sequenceandstop_sequenceare bitpacked to minimize the ram impact. Every command begins with a command byte followed by a byte to determine the parameter count and delay. When the top bit of the second byte is 1 (0x80), a delay will occur after the command parameters are sent. The remaining 7 bits are the parameter count excluding any delay byte. The bytes following are the parameters. When the delay bit is set, a single byte after the parameters specifies the delay duration in milliseconds.

Manage updating a display over I2C in the background while Python code runs. It doesn’t handle display initialization.
Create a I2CDisplay object associated with the given I2C bus and reset pin.
The I2C bus and pins are then in use by the display until
displayio.release_displays()is called even after a reload. (It does this so CircuitPython can use the display after your code is done.)

It’s easiest to use on a board with a built in display such as the Hallowing M0 Express.
import board import displayio import time import pulseio board.DISPLAY.auto_brightness = False board.DISPLAY.brightness = 0 splash = displayio.Group() board.DISPLAY.show(splash) odb = displayio.OnDiskBitmap('/sample.bmp') face = displayio.TileGrid(odb, pixel_shader=odb.pixel_shader) splash.append(face) # Wait for the image to load. board.DISPLAY.refresh(target_frames_per_second=60) # Fade up the backlight for i in range(100): board.DISPLAY.brightness = 0.01 * i time.sleep(0.05) # Wait forever while True: pass
Create an OnDiskBitmap object with the given file.
- Paramètres:
file (file) – The name of the bitmap file. For backwards compatibility, a file opened in binary mode may also be passed.

This allows you to:
palette[0] = 0xFFFFFF # set using an integer palette[1] = b'\xff\xff\x00' # set using 3 bytes palette[2] = b'\xff\xff\x00\x00' # set using 4 bytes palette[3] = bytearray(b'\x00\x00\xFF') # set using a bytearay of 3 or 4 bytes palette[4] = (10, 20, 30) # set using a tuple of 3 integers

Position a grid of tiles sourced from a bitmap and pixel_shader combination. Multiple grids can share bitmaps and pixel shaders.
A single tile grid is also known as a Sprite.
Create a TileGrid object. The bitmap is source for 2d pixels. The pixel_shader is used to convert the value and its location to a display native pixel color. This may be a simple color palette lookup, a gradient, a pattern or a color transformer.
