This patch also uses proper atomic lock/unlock around SD card read/write, adds SD.info() function, and gives error code for failed read/writes. 2014-09-15T21:34:07+00:00 Felix Domke tmbinc@elitedvb.net 2014-09-05T11:47:33+00:00 urn:sha1:09de030651b95956eb9f899e850f24d0ce804460 2014-08-25T17:12:44+00:00 Damien George damien.p.george@gmail.com 2014-08-25T17:12:44+00:00 urn:sha1:34e43c7ee9700249dc6e5b333b7c264d45d6b530 SysTick IRQ now increases millisecond counter directly (ie without calling HAL_IncTick). Provide our own version of HAL_Delay that does a wfi while waiting. This more than halves power consumption when running a loop containing a pyb.delay call. It used to be like this, but new version of HAL library regressed this feature. 2014-08-06T21:33:31+00:00 Damien George damien.p.george@gmail.com 2014-08-06T21:33:31+00:00 urn:sha1:3ef911345c94a6d612ab50c1e912e81cb2cc3f71 This patch updates ST's HAL to the latest version, V1.3.0, dated 19 June 2014. Files were copied verbatim from the ST package. Only change was to suppress compiler warning of unused variables in 4 places. A lot of the changes from ST are cosmetic: comments and white space. Some small code changes here and there, and addition of F411 header. Main code change is how SysTick interrupt is set: it now has a configuration variable to set the priority, so we no longer need to work around this (originall in system_stm32f4xx.c). 2014-04-19T23:16:30+00:00 Damien George damien.p.george@gmail.com 2014-04-19T23:16:30+00:00 urn:sha1:d689430e790bfbd40a4fc3139b118aee5576baf7 Also some updates to compile with latest changes to core py. 2014-03-13T23:17:01+00:00 Dave Hylands dhylands@gmail.com 2014-03-13T22:40:34+00:00 urn:sha1:9db719bb57626d72ab84ab0ccd2294bf89158762 2014-03-12T06:55:41+00:00 Dave Hylands dhylands@gmail.com 2014-03-12T06:55:41+00:00 urn:sha1:dd38d907244bc0e483c3d760f2ba464a394ec229 This compiles and links, but hasn't been tested on a board yet and even if it was run, it doesn't currently do anything.
