Detecting a "true" touch on a touchscreen without rebuilding the TSC driver?

Greetings! Our BBB-based device sometimes operates close to a “hefty” electromagnetic-emitting source, and this scenario can lead to “phantom” touches registering in the system when the screen was NOT actually touched. I was looking at something like evdev or libevent that is configurable and already present in the Debian 11 (kernel 5.10.168-ti-r83) that we’re running to help filter out these “phantom” touch events, like through a pressure threshold or similar.

Thoughts? Suggestions? I’m open to anything that won’t require I directly tweak the TI TSC driver itself and rebuild it. :slight_smile:

TIA!

maybe tuning, ti-charge-delay: Making sure you're not a bot!

Ah, this is new to me, appreciate the suggestion, @RobertCNelson!
