the WS2812B is an intelligent control LED light source, with the control circuit and RGB chip integrated directly into a 5050 RGB LED. As a digital LED strip, each addressable LED has an integrated driver that allows the brightness and color of each LED to be controlled individually, that is, an LED can be of both a different color and brightness to the one next to it. This enables us to create beautiful and complex lighting effects.
The Library masters ws2812b is the full function driver of the ws2812b neopixel GRB series. The driver is writte C language with Code Blocks, It provides the functions to control The RGB.
- The interface .C file expect below functions to correctly link the driver
- ws2812b_interface_write_zero_instruction (Mandatory)
- ws2812b_interface_write_one_instruction (Mandatory)
- delay function ( Mandatory )
- print function (optional )
- refer to video: "coming soon..."
