//| the display is determined by the number of rgb and address pins and the number of tiles:
//| ``len(rgb_pins) // 3 * 2 ** len(address_pins) * abs(tile)``. With 6 RGB pins, 4
//| address lines, and a single matrix, the display will be 32 pixels tall. If the optional height
//| parameter is specified and is not 0, it is checked against the calculated
//| height.
//| """Create a Is31fl3741 object with the given attributes.
//|
//| Up to 30 RGB pins and 8 address pins are supported.
//|
//| The RGB pins must be within a single "port" and performance and memory
//| usage are best when they are all within "close by" bits of the port.
//| The clock pin must also be on the same port as the RGB pins. See the
//| documentation of the underlying protomatter C library for more
//| information. Generally, Adafruit's interface boards are designed so
//| that these requirements are met when matched with the intended
//| microcontroller board. For instance, the Feather M4 Express works
//| together with the RGB Matrix Feather.
//|
//| The framebuffer is in "RGB565" format.
//|
//| "RGB565" means that it is organized as a series of 16-bit numbers
//| where the highest 5 bits are interpreted as red, the next 6 as
//| green, and the final 5 as blue. The object can be any buffer, but
//| `array.array` and ``ulab.ndarray`` objects are most often useful.
//| To update the content, modify the framebuffer and call refresh.
//| 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().
//|
//| If doublebuffer is False, some memory is saved, but the display may
//| flicker during updates.
//|
//| A Is31fl3741 is often used in conjunction with a
//| `framebufferio.FramebufferDisplay`."""
