LED Matrix Editor with Copy/Paste array values

This a just a quick post to share a simple tool I created to make it easier to generate hex values for custom LED matrix patterns on the UNO R4. It's nearly the same as the LED Matrix Editor provided by Arduino, but my tool allows easy copy and paste of the formatted byte array or hex values used in the Arduino_LED_Matrix.h frame-writing function calls. You just run the .html file in your local browser. I couldn't find the same functionality elsewhere. I hope this is helpful to others.

That’s an excellent tool. I already wrote some code to convert eight uint16_t values into three uint32_t values. So it used 128 bits for the 96 bit display. But I could write the bitmap like this:

uint16_t img[] =
{
    0b000000000000,
    0b000011110000,
    0b001100001100,
    0b010000000010,
    0b010000000010,
    0b001100001100,
    0b000011110000,
    0b000000000000,
};
