#Sipeed Maix BIT


Since the release of Seeeduino in 2008, Seeed has been contributing software to the Arduino community. Today we have released new software: ArduinoCore-k210.

Based on kendryte-standalone-sdk, we added the full ArduinoCore-API interface to support Arduino IDE, Linux, Windows, Mac OS X and other development environments. With the support of the ArduinoCore-k210, all k210-based development boards can run Grove Arduino Library and many excellent Arduino libraries in the community of Arduino.

Here’s how to use the ArduinoCore-k210:

Use WS2812 on the Sipeed Maix Bit

Use Grove AI EDGE COMPUTING(Just engineering samples) with Grove modules

ArduinoCore-k210 is also supported as a normal IDE. For example, when developing kendryte-standalone-sdk, you also can use the Arduino Library WS2812FX.

#include <WS2812FX.h>

#define LED_COUNT 32

#define LED_PIN 13

#define TIMER_MS 5000

// Parameter 1 = number of pixels in strip

// Parameter 2 = Arduino pin number (most are valid)

// Parameter 3 = pixel type flags, add together as needed:

//   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)

//   NEO_KHZ400  400 KHz (classic ‘v1’ (not v2) FLORA pixels, WS2811 drivers)

//   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products)

//   NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)

//   NEO_RGBW    Pixels are wired for RGBW bitstream (NeoPixel RGBW products)

WS2812FX ws2812fx = WS2812FX(LED_COUNT, LED_PIN, NEO_RGB + NEO_KHZ800);

unsigned long last_change = 0;

unsigned long now = 0;
