From 15a8a05595c72d328abdea8e3b23f1b558cc46bf Mon Sep 17 00:00:00 2001 From: Gerhard Sittig Date: Sun, 28 Jan 2018 20:49:48 +0100 Subject: graycode, morse, pwm, usb_request, wiegand: cope with absent sample rate Improve robustness of some more protocol decoders. Few of them never checked for the availability of a sample rate in the first place, others checked for the presence of a spec but would not cope with a value of 0. Some checked the value only after processing it, which could result in runtime errors. This change is motivated by bug #1118. --- decoders/usb_request/pd.py | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'decoders/usb_request') diff --git a/decoders/usb_request/pd.py b/decoders/usb_request/pd.py index a480284..e77debc 100644 --- a/decoders/usb_request/pd.py +++ b/decoders/usb_request/pd.py @@ -171,7 +171,8 @@ class Decoder(srd.Decoder): def metadata(self, key, value): if key == srd.SRD_CONF_SAMPLERATE: self.samplerate = value - self.secs_per_sample = float(1) / float(self.samplerate) + if self.samplerate: + self.secs_per_sample = float(1) / float(self.samplerate) def start(self): self.out_binary = self.register(srd.OUTPUT_BINARY) -- cgit v1.2.3-70-g09d2
