Detailed Description
Class for driving triangular GlowBit modules.
Constructor & Destructor Documentation
◆ __init__()
| def glowbit.triangle.__init__ | ( | self, | |
numTris = 1, |
|||
LEDsPerTri = 6, |
|||
pin = 18, |
|||
brightness = 20, |
|||
rateLimitFPS = 20, |
|||
sm = 0 |
|||
| ) |
Initialisation routine for triangular GlowBit modules and tiled arrays thereof.
- Parameters
-
numTris The number of triangle modules in the tiled array. LEDsPerTri The number of LEDs on each triangular module. pin The GPIO pin connected to the GlowBit stick module. Defaults to 18 as that pin is compatible with the Raspberry Pi and Raspberry Pi Pico. Any pin can be used on the Raspberry Pi Pico, only pins 18 and 12 are valid on the Raspberry Pi. brightness The relative brightness of the LEDs. Colours drawn to the internal buffer should be in the range [0,255] and the brightness parameter scales this value before drawing to the physical display. If brightness is an integer it should be in the range [0,255]. If brightness is floating point it is assumed to be in the range [0,1.0]. rateLimitFPS The maximum frame rate of the display in frames per second. The pixelsShow() function blocks to enforce this limit. sm (Raspberry Pi Pico only) The PIO state machine to generate the GlowBit data stream. Each connected GlowBit display chain requires a unique state machine. Valid values are in the range [0,7].
Member Function Documentation
◆ fillTri()
| def glowbit.triangle.fillTri | ( | self, | |
| tri, | |||
| colour | |||
| ) |
Fills all LEDs on a given triangle with the same colour.
- Parameters
-
tri The triangle to fill. The first triangle is addressed with 0. colour A 32-bit GlowBit colour value
