The “solution” I came up with was simply to use the cursor positioning feature to write to the lines I wanted. Since you’re writing strings anyway, it’s not terribly difficult to do. If you’re making a...

Perfect timing! I’ve been using the smaller version of these, loaded with some custom firmware, as airsoft spawn timers. They work great, but the displays needed to be a little bigger. I’ve just been...
