In this video, we examine the WS2812B RGB LED device, and write a bit-banged driver from scratch for an STM32 microcontroller.
Chapters
00:00 What is a WS2812 / NeoPixel
02:33 Hardware overview
06:00 What is a "device driver"?
08:35 The signalling protocol
15:00 Reviewing the datasheet
22:00 Figuring out the GPIO timing
49:32 First LED test
53:36 Implementing the driver interface

![Building A Language Parser and Interpreter [Parser Combinators from Scratch] Episode 5](https://i.ytimg.com/vi/PzodUuERBZc/mqdefault.jpg "Building A Language Parser and Interpreter [Parser Combinators from Scratch] Episode 5
In this episode we dive into parsing recursive structures, and build a very simple functional language parser and interpreter.
=[ ℹ About ℹ ]=
During this series we will develop an understanding of the concept of parsing, and build our own parser combinator system from scratch. The system we build will be capable of parsing both binary and text data. Well make use of both object-oriented and function programming principles to develop an effective and intuitive library.
