suspect-devices/circuitpython/stmhal/timer.c, branch v1.1 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.1 2014-05-03T22:27:38+00:00 Add license header to (almost) all files. 2014-05-03T22:27:38+00:00 Damien George damien.p.george@gmail.com 2014-05-03T22:27:38+00:00 urn:sha1:04b9147e150d2d6fa3750f312fe328b6a71c1b28 Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/. stmhal: Remove #include <stdint.h> from mpconfigport.h. 2014-05-03T12:24:21+00:00 Damien George damien.p.george@gmail.com 2014-05-03T12:24:21+00:00 urn:sha1:5874c1c92baac65834c4684e913ca0a7d8db8f50 Make include dependencies neater, and adheres to the coding convention that headers should not include headers. stmhal: Add documentation for DAC and Timer classes. 2014-05-02T15:58:15+00:00 Damien George damien.p.george@gmail.com 2014-05-02T15:58:15+00:00 urn:sha1:3eb8163b16bc5b6ea30428b54dee60e5c7e9c98f Simplify names for argcheck.c / arg parsing. 2014-04-26T10:19:17+00:00 Damien George damien.p.george@gmail.com 2014-04-26T10:19:17+00:00 urn:sha1:dbc81df5d4822b3a0fc31ea1c5684b0101e193dd Add ARRAY_SIZE macro, and use it where possible. 2014-04-26T09:47:29+00:00 Damien George damien.p.george@gmail.com 2014-04-26T09:47:29+00:00 urn:sha1:6d3c5e4301df363055dc256e6692c610e4d0b918 stmhal, timer: Remove obsolete global variable. 2014-04-21T17:19:50+00:00 Damien George damien.p.george@gmail.com 2014-04-21T17:19:50+00:00 urn:sha1:6691c9e655c7ce98cb80a6629f890881e6c24f1a stmhal: Add Timer class: simple TIM control, incl callback on IRQ. 2014-04-21T15:48:16+00:00 Damien George damien.p.george@gmail.com 2014-04-21T15:48:16+00:00 urn:sha1:7fdfa93700e0f5a5381a57bca3c45865c720dc2f Simple but functional timer control. More sophistication will eventually be added, or for now just use direct register access :) Also added pyb.freq() function to get MCU clock frequencies. stmhal: Improve flash storage cache management. 2014-04-16T22:08:36+00:00 Damien George damien.p.george@gmail.com 2014-04-16T22:08:36+00:00 urn:sha1:6d983539bcff2a540dd136a7e84e1db2b334528f Internal flash used for the filesystem is now written (from the cache) only after a 5s delay, or when a file is closed, or when the drive is unmounted from the host. This delay means that multiple writes can accumulate in the cache, and leads to less writes to the flash, making it last longer. It's implemented by a high-priority interrupt that takes care of flash erase and write, and flushing the cache. This is still only an interim solution for the flash filesystem. It eventually needs to be replaced with something that uses less RAM for the cache, something that can use more of the flash, and something that does proper wear levelling. stmhal: Add ADC function to read data at a given frequency. 2014-04-15T18:52:56+00:00 Damien George damien.p.george@gmail.com 2014-04-15T18:52:56+00:00 urn:sha1:4d7f4eb6a924f4df458eda2e624f429d67ef2248 Reads ADC values into a bytearray (or similar) at a fixed rate. Needs a better name and improved API. Also fix up DAC dma function (which also needs a better name and API). py: Change nlr_jump to nlr_raise, to aid in debugging. 2014-04-05T17:32:08+00:00 Damien George damien.p.george@gmail.com 2014-04-05T17:32:08+00:00 urn:sha1:ea13f407a392593e7746131952a57bad222ee882 This does not affect code size or performance when debugging turned off. To address issue #420.
