Blinkp

 blinkp.clear() 
 blinkp.show_and_exit() 
 

 blinkp.num_pixels 
  Total number of pixels. 
  -> 8 
  This value is constant. 
  
 blinkp.elapsed_time 
  Total number of seconds elapsed since the beginning of program execution. 

 r, g, b, brightness? = blinkp.get_pixel(index) 
  Get RGB values and brightness of the pixel at index. 
  The brightness return variable is optional. 
  -> r: integer between 0 and 255 
  -> g: integer between 0 and 255 
  -> b: integer between 0 and 255 
  -> brightness: number between 0.0 and 1.0 
  -> index: integer between 0 and blinkp.num_pixels-1 
  
 blinkp.set_pixel(index, r, g, b, brightness?) 
  Set pixel at index with RGB values r g b and the specified brightness. 
  The brightness argument is optional; if not used, it keeps the previous value. 
  -> index: integer between 0 and blinkp.num_pixels-1 
  -> r: integer between 0 and 255 
  -> g: integer between 0 and 255 
  -> b: integer between 0 and 255 
  -> brightness: number between 0.0 and 1.0 
  Changes take effect after the next call to 
   blinkp.show_and_wait or blinkp.show_and_exit. 
  
 blinkp.clear() 
  Shorthand for blinkp.set_all(0, 0, 0). 
  
 blinkp.set_all(r, g, b, brightness?) 
  Equivalent to calling blinkp.set_pixel for all pixels: 
   blinkp.set_pixel(0, r, g, b, brightness?) 
   blinkp.set_pixel(1, r, g, b, brightness?) 
   ... 
   blinkp.set_pixel(blinkp.num_pixels-1, r, g, b, brightness?) 
  
 blinkp.set_brightness(brightness) 
  Set the brightness value of all pixels to brightness. 
  -> brightness: number between 0.0 and 1.0 
  Changes take effect after the next call to 
   blinkp.show_and_wait or blinkp.show_and_exit. 
  
 blinkp.show_and_wait(milliseconds) 
  Commit changes to the display and wait the specified milliseconds 
   before continuing execution by restarting the program counter. 
  
 blinkp.show_and_exit() 
  Commit changes to the display and halt the program.
  
 y, i, q = blinkp.rgb_to_yiq(r, g, b) 
 r, g, b = blinkp.yiq_to_rgb(y, i, q) 
 h, l, s = blinkp.rgb_to_hls(r, g, b) 
 r, g, b = blinkp.hls_to_rgb(h, l, s) 
 h, s, v = blinkp.rgb_to_hsv(r, g, b) 
 r, g, b = blinkp.hsv_to_rgb(h, s, v) 
  Convert values between different color spaces.
