我正在尝试在我的 Arduino LED 屏幕上显示电池图标。为此，我需要该图标的像素级阵列(矩阵)。有没有什么方法或工具可以让我上传图像，然后它会给我该图像的像素表示？
最佳答案
假设您知道如何在 LCD 屏幕上设置单个像素并具有 linux shell 访问权限，我可以想出一种在 Arduino 源代码中对图像进行硬编码的方法。虽然这种做法不是那么实用，但肯定是可行且有趣的。所以，让我们开始吧!
假设你想显示这个图标
命名为 nuclear.png。
通过使用 ImageMagick package 中的convert 工具您可以通过以下命令获得一个文本文件，其中列出了图像中的每个像素:
convert nuclear.png nuclear.txt
上面的命令输出了下面的文件nuclear.txt:

很容易看出，除了第一行，每一行都是一个像素坐标，后面是对应的RGBA颜色值。您可以在 official documentation 中获得有关此格式的更多信息。 .
通过在 nuclear.txt 上使用一些管道 shell 命令，我们可以在 nuclear.cpp 中生成一个硬编码的整数数组:
(echo "int pixels[] = {"; \
tail -n +2 nuclear.txt | tr -cs '0-9.\n' ' ' | \
while read x y r g b junk; do echo " $x,$y,$r,$g,$b,";done; \
echo "-1};") > nuclear.cpp

请注意，pixels 数组的每一行都被格式化为 row,col,r,g,b 和最后一个元素 -1是有意包含的。将此数组粘贴到源代码中后，您可以使用下面的代码片段迭代像素并使用自定义函数在屏幕上显示它们:
int i = 0;
while (pixels[i]>-1) {
int row = pixels[i++];
int col = pixels[i++];
int r = pixels[i++];
int g = pixels[i++];
int b = pixels[i++];
//Show the pixel
//showPixel(row,col,r,g,b); You need to implement that.
}
就是这样!
