SpiBladePtr - profezzorn/ProffieOS GitHub Wiki

SpiBladePtr can have up to 10 arguments, but only the first three are required.

SpiBladePtr<leds, data_pin, clock_pin, byte_order, power_pins, max_frequency, pin_class, power_off_delay>

• leds - number of leds in this pixel string, must be less or equal to maxLedsPerSrtring
• data_pin - pin to output SPI data
• clock_pin - pin to output SPI clock
• byte_order - specifies in which orders the colors are sent to the pixels
• power_pins - which pads powers the string, defaults to PowerPINS<bladePowerPin1, bladePowerPin2, bladePowerPin3>
• max_frequency - maximum data rate, defaults to 800000
• pin_class - This is the driver class, defaults to SpiLedPin
• power_off_delay - milliseconds before turning off the power

data_pin and clock_pin is normally one of:

bladePin
blade2Pin
blade3Pin
blade4Pin
blade5Pin
blade6Pin
blade7Pin

Other pins may or may not work depending on what board and driver is being used.

byte_order depends on what kind of pixel strip is used, these values are possible:

Color8::BGR
Color8::BRG
Color8::GBR
Color8::GRB
Color8::RBG
Color8::RGB
Color8::BGRW
Color8::BRGW
Color8::GBRW
Color8::GRBW
Color8::RBGW
Color8::RGBW
Color8::WBGR
Color8::WBRG
Color8::WGBR
Color8::WGRB
Color8::WRBG
Color8::WRGB
Color8::BGRw
Color8::BRGw
Color8::GBRw
Color8::GRBw
Color8::RBGw
Color8::RGBw
Color8::wBGR
Color8::wBRG
Color8::wGBR
Color8::wGRB
Color8::wRBG
Color8::wRGB

By far the most common byte order is GRB, but some pixel strips use RGB byte order. The four-letter byte orders are used for RGBW strips, the most common of those are GRBW and RGBW. The byte orders will capitol W will use both RGB AND W for white colors, while byte orders will lower-case w will only turn on the white LED for white colors. Thus RGBw is more power efficient than RGBW, but not as bright.
