From 6ca7aa50829904240ea07bcb7594c838ec467b98 Mon Sep 17 00:00:00 2001 From: Stefan Brüns Date: Tue, 2 Jan 2018 02:17:07 +0100 Subject: Add a trivial "counter" decoder MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This decoder just counts the number of falling and/or rising edges. This is especially useful for diagnosing protocols with a clock signal or a fixed number of transitions per bit, e.g. pulse length coded. It also provides a divider, which can be used to e.g. count the number of words in I²C or SPI transfers. --- decoders/counter/__init__.py | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 decoders/counter/__init__.py (limited to 'decoders/counter/__init__.py') diff --git a/decoders/counter/__init__.py b/decoders/counter/__init__.py new file mode 100644 index 0000000..e731311 --- /dev/null +++ b/decoders/counter/__init__.py @@ -0,0 +1,28 @@ +## +## This file is part of the libsigrokdecode project. +## +## Copyright (C) 2018 Stefan Brüns +## +## This program is free software; you can redistribute it and/or modify +## it under the terms of the GNU General Public License as published by +## the Free Software Foundation; either version 2 of the License, or +## (at your option) any later version. +## +## This program is distributed in the hope that it will be useful, +## but WITHOUT ANY WARRANTY; without even the implied warranty of +## MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
