Paul Sokolovsky 3a1bbcc2ef extmod: Move fsusermount.c from stmhal for cross-port reuse. 2015-11-25 13:19:36 +02:00
T S 86aa16bea6 stmhal: Implement delayed RTC initialization with LSI fallback. 
If RTC is already running at boot then it's left alone.  Otherwise, RTC is
started at boot but startup function returns straight away.  RTC startup
is then finished the first time it is used.  Fallback to LSI if LSE fails
to start in a certain time.

Also included:
 MICROPY_HW_CLK_LAST_FREQ
        hold pyb.freq() parameters in RTC backup reg
 MICROPY_HW_RTC_USE_US
        option to present datetime sub-seconds in microseconds
 MICROPY_HW_RTC_USE_CALOUT
        option to enable RTC calibration output

CLK_LAST_FREQ and RTC_USE_CALOUT are enabled for PYBv1.0.

Alex March 748509a93c stmhal: FatFS configuration moved to the library folder. 
Port specific settings defined in mpconfigport.

Dave Hylands ea8bf81058 stmhal: Replace #include "stm32f4xx_hal.h" with #include STM32_HAL_H. 2015-07-30 00:38:25 +01:00
Damien George f5d04750db stmhal: Put fs_user_mount pointer in root ptr section of global state. 
Should fix issue #1393.

Damien George 92e9a5e0a7 stmhal: Check if user block device is mounted before accessing it. 
In particular this fixes a bug where pyb.sync (and os.sync) fail because
they try to sync the user mounted device even if it's not mounted.

Damien George 4f94d90d4d stmhal: Include fatfs headers using lib/fatfs prefix. 
This helps make files reusable across other ports.

Damien George 2cf6dfa280 stmhal: Prefix includes with py/; remove need for -I../py. 2015-01-01 21:06:20 +00:00
Damien George 7690b13953 stmhal: Add ability to mount custom block device. 2014-12-27 20:20:51 +00:00
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.

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 6e44381cce stmhal: Improve RTC class; make fatfs use RTC for time stamping files. 2014-04-19 02:17:30 +01:00
Damien George b96c7c03ca stmhal: Move fatfs volume/partition lookup table to ROM. 2014-04-12 00:51:57 +01:00
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 b92d3e1fde stmhal: Add fatfs support, working with flash and SD card. 2014-03-17 14:04:19 +00:00
