touch performance comparison for various versions of ESP32
Posted: Tue Oct 22, 2024 7:55 pm
Hello, I've been experimenting with ESP32 and its touchpad capabilities (in particular using ESP32 arduino library examples), and would like to know if there's any hardware differences between ESP32, ESP32-S2, S3, or any other versions, and whether any of them is better in terms of hardware.
I've taped a 1mm plastic to the top of the touchpads using ESP32, but I've unfortunately only been able to get roughly 3-5% difference in reading, making it maybe harder than I'd like to identify touch events. Does any of the other chips perform better?
