Damien George 3770cd2e70 stmhal: Expose flash and SD card as proper objects with block protocol.
You can now create (singleton) objects representing the flash and SD
card, using:

    flash = pyb.Flash()
    sdcard = pyb.SDCard()

These objects provide the block protocol.

Paul Sokolovsky 5b85a86ce3 extmod/fsusermount: Introduce separate mkfs() function.
Per the previously discussed plan. mount() still stays backward-compatible,
and new mkfs() is rought and takes more args than needed. But is a step
in a forward direction.

Damien George 401af50dc0 stmhal: Add pyb.irq_stats() to get statistics about IRQ calls.
Adds a lot of code, makes IRQs a bit less efficient, but is very useful
for debugging.  Usage: pyb.irq_stats() returns a memory view that can be
read and written, eg:

    list(pyb.irq_stats())
    pyb.irq_stats()[0]
    pyb.irq_stats()[0] = 0

The patch provides general IRQ_ENTER() and IRQ_EXIT() macros that can be
modified to provide further IRQ statistics if desired.

Paul Sokolovsky 3a1bbcc2ef extmod: Move fsusermount.c from stmhal for cross-port reuse. 2015-11-25 13:19:36 +02:00
Damien George 40274fec9c lib/pyexec: Move header pyexec.h from stmhal directory. 2015-11-09 13:13:09 +00:00
Damien George 83158e0e7f stmhal: Implement os.dupterm (was pyb.repl_uart).
pyb.repl_uart still exists but points to os.dupterm.

Damien George d8066e999d stmhal: Add sleep_{ms,us} and ticks_{ms,us,cpu,diff} to time module.
pyb module still has pyb.delay and pyb.udelay, but these now point to
time.sleep_ms and time.sleep_us respectively.

Dave Hylands ea8bf81058 stmhal: Replace #include "stm32f4xx_hal.h" with #include STM32_HAL_H. 2015-07-30 00:38:25 +01:00
Damien George 8657342973 stmhal: Correctly clear wake-up flag before entering standby mode. 2015-03-22 21:52:20 +00:00
Damien George f44ace11fb stmhal: Put flash in deep power-down mode when entering stop mode.
This can get PYBv1.0 stop current down to around 290uA.

Damien George 48ef64a729 stmhal: Make os.sync use disk_ioctl exclusively; reuse os.sync in pyb. 2015-03-04 20:38:28 +00:00
Damien George 4f94d90d4d stmhal: Include fatfs headers using lib/fatfs prefix.
This helps make files reusable across other ports.

Damien George 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.

Damien George 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.

Dave Hylands d7f199465f stmhal: Add support for FEZ Cerb40 II board from ghielectronics.com. 2015-01-21 00:11:04 +00:00
Damien George 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.

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 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).

Damien George 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.
