From d0a2541421b8e7732c519cd3c9dcf848dfc61d30 Mon Sep 17 00:00:00 2001 From: Benedikt Otto Date: Thu, 23 Jul 2020 10:58:27 +0200 Subject: ir_nec: Add dumps for corner cases (timing tolerance, last packet decode) Add file joy_it_sbc_irc01_all.sr which exceeds the previous 5% limit for timing tolerances and would not decode at all. Add file joy_it_sbc_irc01_enter_no_repeat.sr which lacks a repeat code after a key press, which earlier decoder versions would have failed to decode.
