These drivers replace the existing 1-wire and DS18X20 drivers in the drivers/onewire directory. The existing ones were pyboard-specific and not very efficient nor minimal (although the 1-wire driver was written in pure Python it only worked at large enough CPU frequency). This commit brings backwards incompatible API changes to the existing 1-wire drivers. User code should be converted to use the new drivers, or check out the old version of the code and keep a local copy (it should continue to work unchanged). drivers: Replace deprecated Pin.high()/low() methods with .__call__(1/0). 2017-05-21T14:44:58+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-04-23T08:35:34+00:00 urn:sha1:1c9ee497562ab49c00d190ff91b6689979f922f4 drivers/onewire/ds18x20: Fix negative temperature calc for DS18B20. 2017-01-08T08:26:22+00:00 syndycat syndycat@yahoo.com 2017-01-07T11:36:11+00:00 urn:sha1:b2611d6be305c94359f67df875786858e05c3eb0 drivers/onewire: Enable pull up on data pin. 2017-01-03T06:19:22+00:00 Dave Hylands dhylands@gmail.com 2017-01-02T21:02:22+00:00 urn:sha1:3c84197f17d27a991f50cb6e5ed268edbc796991 The driver seems to be be enabling the pullup resistor in most places, but not this one. Making this one little change allows onewire devices to be used with no external pullup resistor. drivers/onewire: Fix ds18x20.read_temp so it works when no rom given. 2015-07-30T22:10:39+00:00 Damien George damien.p.george@gmail.com 2015-07-30T22:10:39+00:00 urn:sha1:a95b06fc6b8adefa91303039cff0a35d3ae45d5a drivers: Add onewire driver and ds18x20 temperature sensor driver. 2015-03-03T01:29:52+00:00 Damien George damien.p.george@gmail.com 2015-03-03T01:29:52+00:00 urn:sha1:9be0d599cd46fb01838cf14207c3d9a1195ceb35
