Now that I have the e-paper display working, I thought it would be fun to create a nametag. One of the great features of e-paper is that once programmed, the display remains after the power is removed making it very suitable for such a purpose.
I started off creating a 250 x 122 pixel image in Canva and downloading it as a PNG image file.
The next step was to convert it to a bitmap image that could be displayed on the e-paper display. I used https://javl.github.io/image2cpp/
This generates a bitmap table you paste into the sketch.
Here’s the sketch…

* Displays VE3AKK/VE3LFO callsign badge from bitmap data
