From 27931d38ce057f36e68bc68cd4bf4ba24bbb9c57 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 9 Nov 2021 22:17:49 -0800 Subject: [PATCH] Input: ili210x - reduce sample period to 15ms Modern devices may redraw display at 60 Hz, make sure we have one input sample per one frame. Reduce sample period to 15ms, so we would get up to 66.6 samples per second, although realistically with all the jitter and extra scheduling wiggle room, we would end up just above 60 samples per second. This should be a good compromise between sampling too often and sampling too seldom.
