I have developed an online binary pixel tool for 128*64 display

I have only tested it in Chrome browser, you can use it from https://12864.github.io/

Some hotkeys: GitHub - 12864/12864: IoT DevKit Pixel Tool

Enjoy :smiley:

Very cool. I'll update the documentation in openGLCD in a future release to provide a link to this with some information on how to use it with the openGLCD library.
BTW, it works with FireFox
