Detailed Description
Wrapper around Adafruit_NeoPixel with Millis() correction.
When the Adafruit_NeoPixel.show() member is called interrupts are temporarily disabled to allow the precise timing required when sending data out to the LEDs. This has a few side-effects, including a drift in the timer which is used by millis().
This is usually a small effect, but when LEDs are updated very frequently the offset can add up and become noticable. In one application, the author noticed the value of millis being 50% slower than real time!
This class is a simple sub-class of the Adafruit_NeoPixel class which estimates the offset to the millis() timer, and updates the offset for the Millis() call.
Constructor & Destructor Documentation
◆ CbNeoPixel()
| CbNeoPixel::CbNeoPixel | ( | uint16_t | n, |
| uint8_t | p = 6, |
||
| neoPixelType | t = NEO_GRB+NEO_KHZ800 |
||
| ) |
Constructor.
Parameter names kept the same as the Adafruit_NeoPixel docs for consistency.
- Parameters
-
n The number of LEDs in the strip. p The pin for the LED data line. t RGB LED type.

Member Function Documentation
◆ show()
| void CbNeoPixel::show | ( | void | ) |
Send updated pixel state to LEDs.
This calls Adafruit_NeoPixel.show() and then makes an adjustment to the Millis() offset, so that Millis() returns about the right time.
