Making this one little change allows onewire devices to be used with no external pullup resistor. 2016-12-01T05:43:25+00:00 Radomir Dopieralski openstack@sheep.art.pl 2016-09-06T18:59:21+00:00 urn:sha1:eb09336e996a71fd58e0638035565946d74a1495 2016-11-03T01:41:11+00:00 Damien George damien.p.george@gmail.com 2016-11-03T01:41:11+00:00 urn:sha1:7bb0f7b0f6218e813ca1ea9a21d5d549c7b36ab9 Following best-practice use of the const feature, to make it compatible with Python. 2016-10-21T05:26:01+00:00 Damien George damien.p.george@gmail.com 2016-10-18T00:49:27+00:00 urn:sha1:571e6f26dbd7e0e38441bc402f76d293303063b2 Builtin functions with a fixed number of arguments (0, 1, 2 or 3) are quite common. Before this patch the wrapper for such a function cost 3 machine words. After this patch it only takes 2, which can reduce the code size by quite a bit (and pays off even more, the more functions are added). It also makes function dispatch slightly more efficient in CPU usage, and furthermore reduces stack usage for these cases. On x86 and Thumb archs the dispatch functions are now tail-call optimised by the compiler. The bare-arm port has its code size increase by 76 bytes, but stmhal drops by 904 bytes. Stack usage by these builtin functions is decreased by 48 bytes on Thumb2 archs. 2016-10-21T05:26:01+00:00 Damien George damien.p.george@gmail.com 2016-10-18T00:06:20+00:00 urn:sha1:4ebdb1f2b217410cdc1cee0e0c0da8fceb7627f2 In order to have more fine-grained control over how builtin functions are constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific, with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW. These names now match the MP_DEFINE_CONST_FUN_OBJ macros. 2016-10-07T02:53:34+00:00 Damien George damien.p.george@gmail.com 2016-10-07T02:53:34+00:00 urn:sha1:e3d29996b3d0b1a81bd3dcc1d139e0a6ee233b03 2016-09-01T07:44:07+00:00 Radomir Dopieralski openstack@sheep.art.pl 2016-08-25T08:54:59+00:00 urn:sha1:ce1c786297e69df4a82e83ac379f8ef068e709f6 With backwards compatibility for pyboard. 2016-07-11T20:11:25+00:00 Damien George damien.p.george@gmail.com 2016-07-11T20:11:25+00:00 urn:sha1:dfe056df6f7cdcee41965247fbbf03b4c34c012a Otherwise gcc 6.1.1 raises a misleading-indentation error. 2016-06-26T12:09:31+00:00 Radomir Dopieralski openstack@sheep.art.pl 2016-06-14T08:50:29+00:00 urn:sha1:ab8a5d51999b5c9214004200a8e0528caf160cc6 In particular, the WeMOS D1 Mini board comes with a shield that has a 64x48 OLED display. This patch makes it display properly, with the upper left pixel being at (0, 0) and not (32, 0). I tried to do this with the configuration commands, but there doesn't seem to be a command that would set the column offset (there is one for the line offset, though).
