基于esp32的ws2812点阵rgb屏幕开源项目
开源代码库如下，代码是arduino框架下的历程，具体项目未完成
# /*
#像素信息协议数组 : information = {{x,y,r,g,b} , ---第一个像素信息
# {x,y,r,g,b} ...} ---第二个像素信息
#*/
#我写了一个图片转数组的脚本，可以大大提高转换效率，后期我也会将这个脚本转化软件
import cv2
cv2.namedWindow('new',cv2.WINDOW_NORMAL)

#规定显示的照片尺寸
re_x = 8
re_y = 8

cv2.imshow('new',img)
print(img.shape)

以下是程序源代码，可以进行多平台移植，移植时只需要将void drawRGBpoint(uint8_t x, uint8_t y, uint8_t r, uint8_t g, uint8_t b)函数里的pixels0.setPixelColor(x, pixels0.Color(r, g, b));改为对应单片机信号输出函数即可
