stmhal: Correctly clear wake-up flag before entering standby mode.
2015-03-22 21:52:20 +00:00
f44ace11fb
stmhal: Put flash in deep power-down mode when entering stop mode.
...
This can get PYBv1.0 stop current down to around 290uA.

48ef64a729
stmhal: Make os.sync use disk_ioctl exclusively; reuse os.sync in pyb.
2015-03-04 20:38:28 +00:00
4f94d90d4d
stmhal: Include fatfs headers using lib/fatfs prefix.
...
This helps make files reusable across other ports.
2015-03-04 20:35:41 +00:00
0b32e50365
stmhal: Make pybstdio usable by other ports, and use it.
...
Now all ports can use pybstdio.c to provide sys.stdin/stdout/stderr, so
long as they implement mp_hal_stdin_* and mp_hal_stdout_* functions.

d39c7aa517
stmhal: Add Python-configurable USB HID mode.
...
Different HID modes can be configured in Python. You can either use
predefined mouse or keyboard, or write your own report descriptor.

d7f199465f
stmhal: Add support for FEZ Cerb40 II board from ghielectronics.com.
2015-01-21 00:11:04 +00:00
3b51b3e90f
stmhal: Collect all root pointers together in 1 place.
...
A GC in stmhal port now only scans true root pointers, not entire BSS.
This reduces base GC time from 1700ms to 900ms.

stmhal: Prefix includes with py/; remove need for -I../py.
2015-01-01 21:06:20 +00:00
7690b13953
stmhal: Add ability to mount custom block device.
2014-12-27 20:20:51 +00:00
008251180d
stmhal: Enhance pyb.freq to configure bus (AHB, APB1, APB2) freqs.
...
This is useful if you need precise control over the speed of
peripherals (eg SPI clock).

1960475ed7
stmhal: Make pyb.[u]delay use systick with IRQs, busy loop otherwise.
...
pyb.delay and pyb.udelay now use systick if IRQs are enabled, otherwise
they use a busy loop. Thus they work correctly when IRQs are disabled.
The busy loop is computed from the current CPU frequency, so works no
matter the CPU frequency.

Use MP_DEFINE_CONST_DICT macro to define module dicts.
...
This is just a clean-up of the code. Generated code is exactly the
same.
2014-11-29 14:39:27 +00:00
38bd762121
stmhal: Improve pyb.freq to allow 8 and 16MHz (not usable with USB).
...
Also restrict higher frequencies to have a VCO_OUT frequency below
432MHz, as specified in the datasheet.
Docs improved to list allowed frequencies, and explain about USB
stability.

Add pyb.hard_reset, and make sys.exit() or raise SystemExit do a soft reset.
2014-10-22 19:14:20 +01:00
9b6617ea8b
stmhal: Add pyb.stop() and pyb.standby() functions.
2014-10-09 19:02:47 +01:00
d03c681608
stmhal: Use mp_uint_t where appropriate.
...
Found these by compiling stmhal with mp_uint_t of type uint32_t instead
of unsigned int. This actually makes a difference to the code, but just
a curiosity.

stmhal: Add config option to disable/enable CAN driver.
2014-10-05 18:05:26 +01:00
24119176e7
stmhal: Allow pyb.freq() function to change SYSCLK frequency.
...
Eg pyb.freq(120000000) sets the CPU to 120MHz. The frequency can be set
at any point in the code, and can be changed as many times as you like.
Note that any active timers will need to be reconfigured after a freq
change.
Valid range is 24MHz to 168MHz (but not all freqs are supported). The
code maintains a 48MHz clock for the USB at all times and it's possible
to change the frequency at a USB REPL and keep the REPL alive (well,
most of the time it stays, sometimes it resets the USB for some reason).
Note that USB does not work with pyb.freq of 24MHz.

stmhal: Add basic CAN bus support.
