* monitor_nmea0183: Convert to deg_to_str2().Gary E. Miller2019-02-221-12/+8
|
* deg_to_s() and calls to it: Allow negative degrees, use fabs().Gary E. Miller2019-02-221-4/+2
| | | | | Every call to deg_to_s() was preceded by a fabs(deg). So move the fabs() into deg_to_s().
* LICENSE: Update licenses for consistency. No functional changes.Gary E. Miller2018-11-191-1/+1

* monitor_nmea0813: isnan() -> isfinite(). Fix a buffer size.Gary E. Miller2018-07-141-3/+3
| | | | Thanks to Virgin Orbit for their support on this patch.
* SPDXify the licerse references.Eric S. Raymond2018-03-081-1/+1

* for vsnprintf() FreeBSD wants __ISO_C_VISIBLE >= 1999Gary E. Miller2016-08-161-0/+4
| | | | | Sad, C99 did not actually standardize the defines to invoke the standard.
* Make asynchronous updating of PPS windows more reliable.Eric S. Raymond2016-01-041-0/+1
| | | | Generalizes a patch for monitor_ubx.c submitted by by Nuno Gonçalves.
* Address Savannah bug #46082 - Can't explicitly build with NMEA drivers.Eric S. Raymond2015-10-011-4/+4

* More trailing whitespace fixups.Gary E. Miller2015-04-301-1/+1

* Retire splint from our set of static analyzers.Eric S. Raymond2015-03-301-8/+0
| | | | | | | | | | | | | | | | | | | The proximate cause was that we've been seing emission of error messages that were randomly and disturbingly variable across different environments - notably Raspbian and Gentoo splint gave nontrivially different results than Ubuntu 14.10 splint. And this was *not* due to Ubuntu patches! A pristine splint built from the 3.1.2 tarball on Ubuntu didn't match the Raspbian and Gentoo results either. But this has been coming for a while. Easy access to more modern static analyzers such as coverity, scan-build and cppcheck has been decreasing the utility of splint, which is unmaintained and somewhat buggy and not easy to use. Only file not cleaned is ppsthread.c, because Gary has been working on it during this cleanup. All regression tests pass. PPS observed live on GR601-W.
* Fix fatal typo in gpsmon.Eric S. Raymond2015-02-241-1/+1

* In gpsmon, refactor so PPS field updates are done by common code.Eric S. Raymond2015-02-241-22/+1
|
* gpsmon: refactoring step, make utility function for TOS display.Eric S. Raymond2015-02-241-19/+1
|
* TOFF display in gpsmon.Eric S. Raymond2015-02-241-7/+10
|
* Incomplete TOFF display code for gpsmon in NMEA0183 mode.Eric S. Raymond2015-02-231-5/+31
| | | | Fields have been moved to accommodate TOFF but it is not yet displayed.
* monitor_nme0183.c: factor out a utility function.Eric S. Raymond2015-02-231-18/+27
| | | | gpsmon behavior is unchanged.
* In NMEA0183 monitor, macroize some magic numbers.Eric S. Raymond2015-02-231-16/+20
| | | | | | We're going to use them to move fields around. gpsmon shows PPS in direct mode.
* Abolish all confusing uses of the word 'drift' for a time delta.Eric S. Raymond2015-02-231-3/+3
| | | | No logic changes. All regression tesrs pass. Live PPS observed.
