|
||||
//|
|
||||
//| Create a Protomatter object with the given attributes. The height of
|
||||
//| the display is determined by the number of rgb and address pins:
|
||||
//| len(rgb_pins)/3 * 2 ** len(address_pins). With 6 RGB pins and 4
|
||||
//| address lines, the display will be 32 pixels tall.
|
||||
//|
|
||||
//| 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.
|
||||
//|
|
||||
//| When specified as True, double buffering can reduce some flickering of
|
||||
//| the matrix; however, this increases memory usage.
|
||||
//|
|
||||
//| The framebuffer is in "RGB565" format. If a framebuffer is not
|
||||
//| passed in, one is allocated and initialized to all black. To update
|
||||
//| the content, modify the framebuffer and call swapbuffers.
|
||||
//|
|
||||
//| If doublebuffer is False, some memory is saved, but the display may
|
||||
//| flicker during updates.
|
||||
//|
|
||||
//| If a framebuffer is not passed in, one is allocated internally. To
|
||||
//| retrieve it, pass the protomatter object to memoryview().
