ws2801.init()¶
Initializes the module and sets the pin configuration.
Syntax¶
ws2801.init(pin_clk, pin_data)
Parameters¶
pin_clk
pin for the clock. Supported are GPIO 0, 2, 4, 5.pin_data
pin for the data. Supported are GPIO 0, 2, 4, 5.
Returns¶
nil
ws2801.write()¶
Sends a string of RGB Data in 24 bits to WS2801. Don't forget to call ws2801.init()
before.
Syntax¶
ws2801.write(string)
Parameters¶
string
payload to be sent to one or more WS2801. It should be composed from an RGB triplet per element.R1
the first pixel's red channel value (0-255)G1
the first pixel's green channel value (0-255)B1
the first pixel's blue channel value (0-255)
... You can connect a lot of WS2801...R2
,G2
,B2
are the next WS2801's Red, Green, and Blue channel values
Returns¶
nil
Example¶
ws2801.write(string.char(255,0,0, 0,255,0, 0,0,255))
