-/* Single-File-Header for using asynchronous LEDs with the CH32V003 using DMA to the SPI port.
-   I may write another version of this to use DMA to timer ports, but, the SPI port can be used
-   to generate outputs very efficiently. So, for now, SPI Port.  Additionally, it uses FAR less
-   internal bus resources than to do the same thing with timers.

-   For the CH32V003 this means output will be on PORTC Pin 6
