class is31fl3741.IS31FL3741(*, width: int)

Create a IS31FL3741 object with the given attributes.

The framebuffer is in “RGB888” format using 4 bytes per pixel. Bits 24-31 are ignored. The format is in RGB order.

If a framebuffer is not passed in, one is allocated and initialized to all black. In any case, the framebuffer can be retrieved by passing the Is31fl3741 object to memoryview().

A Is31fl3741 is often used in conjunction with a framebufferio.FramebufferDisplay.

brightness :float

In the current implementation, 0.0 turns the display off entirely and any other value up to 1.0 turns the display on fully.

width :int

The width of the display, in pixels

height :int

The height of the display, in pixels

deinit(self)None

Free the resources associated with this IS31FL3741 instance. After deinitialization, no further operations may be performed.

refresh(self)None

Transmits the color data in the buffer to the pixels so that they are shown.
