From 5e50f877f7ef2309a5318fc6ceed4903d1d80a64 Mon Sep 17 00:00:00 2001 From: Nelson Castillo Date: Thu, 29 Jan 2009 14:27:25 +0000 Subject: [PATCH 8/8] Send pen-up events faster (side effect: improve illume keyboard responsiveness) MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit We were waiting 60ms before reporting a pen-up event to avoid jitter. Now we wait 8ms (actually 5 with HZ == 200). Thanks to Marco Trevisan for testing and pointing out that there was a problem that could be spotted with the illume keyboard. Note that I used the Terminal mode of the keyboard (no dictionary) for tests. I also used touch_test.py and the jitter doesn't seem to be an issue when drawing lines with the finger.
