|description=Driving Neopixel WS2812 addressable RGB LEDs using a RP2350. We will implement a PIO state machine to take care of the timing. We will also demonstrate how efficiency can be increased by offloading the data transfer to DMA.

 As can be seen the overhead is massive.  47 bit required to send a maximum of a 64 bit payload.  The CAN bus is definitely not designed for speed but rather reliability.
