From: Uwe Hermann Date: Tue, 8 Jul 2014 19:32:32 +0000 (+0200) Subject: Various PDs: Throw SamplerateError instead of Exception. X-Git-Tag: libsigrokdecode-0.4.0~207 X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=21cda9512f29947617da45822ab524b1f76f56c1;p=libsigrokdecode.git 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. --- diff --git a/decoders/can/pd.py b/decoders/can/pd.py index e425575..f80ebc6 100644 --- a/decoders/can/pd.py +++ b/decoders/can/pd.py @@ -20,6 +20,9 @@ import sigrokdecode as srd +class SamplerateError(Exception): + pass + class Decoder(srd.Decoder): api_version = 2 id = 'can' @@ -358,8 +361,8 @@ class Decoder(srd.Decoder): self.curbit += 1 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: (can_rx,) = pins diff --git a/decoders/dcf77/pd.py b/decoders/dcf77/pd.py index 3f0ff50..14d8637 100644 --- a/decoders/dcf77/pd.py +++ b/decoders/dcf77/pd.py @@ -25,6 +25,9 @@ import calendar def bcd2int(b): return (b & 0x0f) + ((b >> 4) * 10) +class SamplerateError(Exception): + pass + class Decoder(srd.Decoder): api_version = 2 id = 'dcf77' @@ -245,8 +248,8 @@ class Decoder(srd.Decoder): raise Exception('Invalid DCF77 bit: %d' % c) 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: # Ignore identical samples early on (for performance reasons). diff --git a/decoders/guess_bitrate/pd.py b/decoders/guess_bitrate/pd.py index e86316f..1d7434b 100644 --- a/decoders/guess_bitrate/pd.py +++ b/decoders/guess_bitrate/pd.py @@ -20,6 +20,9 @@ import sigrokdecode as srd +class SamplerateError(Exception): + pass + class Decoder(srd.Decoder): api_version = 2 id = 'guess_bitrate' @@ -53,8 +56,8 @@ class Decoder(srd.Decoder): self.samplerate = value;
