stm32l4.git, branch working

Add a little white flair to the LED strip

2020-12-05T07:05:09+00:00

Added some better implementation around the ws2812b driver.

2020-12-05T06:51:38+00:00

Added kernel-level abstraction over the spi interface.

2020-12-05T06:16:31+00:00

Add systick/...

2020-12-05T03:34:20+00:00

Double the SPI bandwith by writing only 8 bits to the spi data register instead of 16 (with 8 leading 0's).

2020-12-04T05:45:47+00:00

Basic working example with minimal flicker and correct color.

Some changes to linked list

2020-12-03T07:53:04+00:00

Add linked list header.

The lights really work this time.

I also found out that the noise in the lighhts was coming from the USB
debug interface. For whatever reason it doesn't appear that the spi pins
are not well isolated from the debugger noise so unplugging and running
off one power source works pretty well.

Switch flash program to openocd. It is more consistent than st-flash.
