Damien George 1d7fb82f0a stmhal: Change 64-bit arithmetic to 32-bit for SD card block addressing.
By measuring SD card addresses in blocks and not bytes, one can get away
with using 32-bit numbers.

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.

Dave Hylands 994bb4a839 Fix sdcard_power_on to not do anything if the card is already powered on. 2014-08-25 10:16:52 -07:00
Damien George 594699bc88 stmhal: Protect SD_WriteBlocks by IRQ disable/enable pair. 2014-07-07 07:29:06 +01:00
Dave Hylands 90ba80dc36 Disable IRQs around sdcard reads.
Once the code switches to using DMA, this can be removed.

Paul Sokolovsky 8139494e54 stmhal: Include mpconfig.h before all other includes.
It defines types used by all other headers.

Fixes #691.

Damien George 04b9147e15 Add license header to (almost) all files.
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/.

Damien George d553be5982 build: Simplify build directory layout by putting all headers in genhdr.
Any generated headers go in $(BUILD)/genhdr/, and are #included as
'genhdr/xxx.h'.

Damien George df6567e634 Merge map.h into obj.h.
Pretty much everyone needs to include map.h, since it's such an integral
part of the Micro Python object implementation.  Thus, the definitions
are now in obj.h instead.  map.h is removed.

Damien George d17926db71 Rename rt_* to mp_*.
Mostly just a global search and replace.  Except rt_is_true which
becomes mp_obj_is_true.

Still would like to tidy up some of the names, but this will do for now.

Damien George 09d207785c stmhal: Unify naming of HW config; make SD detect configurable.
All board config macros now begin with MICROPY_HW_.

Renamed PYBv10 to PYBV10, since macros should be all uppercase.

Made SDCARD_DETECT configurable in mpconfigport.h, so that the SD
detect pin can be easily configured.

Damien George 9b196cddab Remove mp_obj_type_t.methods entry and use .locals_dict instead.
Originally, .methods was used for methods in a ROM class, and
locals_dict for methods in a user-created class.  That distinction is
unnecessary, and we can use locals_dict for ROM classes now that we have
ROMable maps.

This removes an entry in the bloated mp_obj_type_t struct, saving a word
for each ROM object and each RAM object.  ROM objects that have a
methods table (now a locals_dict) need an extra word in total (removed
the methods pointer (1 word), no longer need the sentinel (2 words), but
now need an mp_obj_dict_t wrapper (4 words)).  But RAM objects save a
word because they never used the methods entry.

Overall the ROM usage is down by a few hundred bytes, and RAM usage is
down 1 word per user-defined type/class.

There is less code (no need to check 2 tables), and now consistent with
the way ROM modules have their tables initialised.

Efficiency is very close to equivaluent.

Damien George c12b2213c1 Change mp_method_t.name from const char * to qstr.
Addresses issue #377.

Damien George fb431bf556 stmhal: Add SD card support.
Just low-level read/write support.  No filesystem yet.
