Description

In this example, we will be using the AmebaD board to control the WS2812B RGB LED, using the SPI peripheral to create the waveform necessary for the LEDs.
WS2812B_Patterns allows you to create different light patterns with many different colors.

Details

BW16 is a dual-frequency Wi-Fi + Bluetooth SoC module developed based on RTL8720DN. It supports dual-frequency (2.4GHz or 5GHz) WLAN and low power Bluetooth 5.0; and integratesARMV8 (Cortex-M4F) high-performance MCU, ARM V8M (Cortex-M0) low-power MCU, WLAN (802.11 a / b / g / n), MAC, Bluetooth and RF baseband, and provides a set of configurable GPIO ports for the control of different peripherals.
