Fix teensy build to use soft-float Add USE_ARDUINO_TOOLCHAIN option to teensy build py: Free non-interned strings in the parser when not needed. 2014-09-23T15:31:56+00:00 Damien George damien.p.george@gmail.com 2014-09-23T15:31:56+00:00 urn:sha1:52b5d76a6b0c5e4c779211fdf7bca56d87a2f83e mp_parse_node_free now frees the memory associated with non-interned strings. And the parser calls mp_parse_node_free when discarding a non-used node (such as a doc string). Also, the compiler now frees the parse tree explicitly just before it exits (as opposed to relying on the caller to do this). Addresses issue #708 as best we can. stmhal: Initialise stack pointer correctly. 2014-09-23T09:59:05+00:00 Damien George damien.p.george@gmail.com 2014-09-23T09:59:05+00:00 urn:sha1:eaaebf3291a12ff65ca5c7f16e0d486fbde10efa Stack is full descending and must be 8-byte aligned. It must start off pointing to just above the last byte of RAM. Previously, stack started pointed to last byte of RAM (eg 0x2001ffff) and so was not 8-byte aligned. This caused a bug in combination with alloca. This patch also updates some debug printing code. Addresses issue #872 (among many other undiscovered issues). stmhal: Add pulse_width_ratio to timer channel object. 2014-09-21T21:54:02+00:00 Damien George damien.p.george@gmail.com 2014-09-21T21:54:02+00:00 urn:sha1:0e58c5810de2717f9707e9eef82cd57a43468a60 This allows to set the pulse width (for PWM mode) as a ratio relative to the period of the timer. Eg, 0.5 is a 50% duty cycle. You can set the ratio in the channel init, or using channel.pulse_width_ratio; the latter can also read the pulse width as a ratio. Add Timer support (PWM, OC, IC) for stmhal and teensy 2014-09-19T16:26:13+00:00 Dave Hylands dhylands@gmail.com 2014-08-20T20:21:11+00:00 urn:sha1:becbc87fd73c98664b472b4a06c2b54558dd5669 stmhal: Fix bugs in documentation so it compiles. 2014-09-17T23:27:42+00:00 Damien George damien.p.george@gmail.com 2014-09-17T23:27:42+00:00 urn:sha1:2842945e760c98793cb0c62a66345ab8850afc1a py: Add native json printing using existing print framework. 2014-09-17T21:56:34+00:00 Damien George damien.p.george@gmail.com 2014-09-17T21:56:34+00:00 urn:sha1:612045f53f7e5edf9faa359ee9ee52d490d58000 Also add start of ujson module with dumps implemented. Enabled in unix and stmhal ports. Test passes on both.
