From 21cda9512f29947617da45822ab524b1f76f56c1 Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Tue, 8 Jul 2014 21:32:32 +0200 Subject: Various PDs: Throw SamplerateError instead of Exception. Also, use the "if not self.samplerate" form, which catches both the case where self.samplerate is None, as well as the case where it is 0. --- decoders/usb_signalling/pd.py | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'decoders/usb_signalling') diff --git a/decoders/usb_signalling/pd.py b/decoders/usb_signalling/pd.py index a21fe8d..59db0d4 100644 --- a/decoders/usb_signalling/pd.py +++ b/decoders/usb_signalling/pd.py @@ -73,6 +73,9 @@ sym_idx = { 'SE1': 3, } +class SamplerateError(Exception): + pass + class Decoder(srd.Decoder): api_version = 2 id = 'usb_signalling' @@ -217,8 +220,8 @@ class Decoder(srd.Decoder): self.oldsym = sym def decode(self, ss, es, data): - if self.samplerate is None: - raise Exception("Cannot decode without samplerate.") + if not self.samplerate: + raise SamplerateError('Cannot decode without samplerate.') for (self.samplenum, pins) in data: # State machine. if self.state == 'IDLE': -- cgit v1.2.3-70-g09d2
