Damien George 731f359292 all: Add py/mphal.h and use it in all ports.
py/mphal.h contains declarations for generic mp_hal_XXX functions, such
as stdio and delay/ticks, which ports should provide definitions for.  A
port will also provide mphalport.h with further HAL declarations.

Tom Soulanille 7731edf2f5 stmhal: Add "opt" arg to pyb.main, to set mp_optimise_value.
Use this to set the global optimisation value when executing the main
script (and all scripts it imports).

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

Henrik Sölver f80f1a7077 stmhal: Add support for CAN rx callbacks. 2015-02-15 03:10:53 +00:00
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 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.

This is so it's compatible with Windows.

Dave Hylands 8d62bbd46a Add pyb.hard_reset, and make sys.exit() or raise SystemExit do a soft reset. 2014-10-22 19:14:20 +01:00
Damien George 481d714bd5 stmhal: Overhaul UART class to use read/write, and improve it.
UART object now uses a stream-like interface: read, readall, readline,
readinto, readchar, write, writechar.

Timeouts are configured when the UART object is initialised, using
timeout and timeout_char keyword args.

The object includes optional read buffering, using interrupts.  You can set
the buffer size dynamically using read_buf_len keyword arg.  A size of 0
disables buffering.

Damien George fec70ad369 stmhal: Remove long-obsolete pybwlan.[ch] files from old CC3k driver. 2014-10-06 15:40:25 +00:00
Damien George 3a1c4c5bc6 stmhal: Add network and usocket module.
As per issue #876, the network module is used to configure NICs
(hardware modules) and configure routing.  The usocket module is
supposed to implement the normal Python socket module and selects the
underlying NIC using routing logic.

Right now the routing logic is brain dead: first-initialised,
first-used.  And the routing table is just a list of registered NICs.

cc3k and wiznet5k work, but not at the same time due to C name clashes
(to be fixed).

Note that the usocket module has alias socket, so that one can import
socket and it works as normal.  But you can also override socket with
your own module, using usocket at the backend.

Damien George 3a2795e200 stmhal: Add label to internal flash drive on creation. 2014-09-29 15:26:11 +01:00
Damien George eaaebf3291 stmhal: Initialise stack pointer correctly.
Stack is full descending and must be 8-byte aligned.  It must start off
pointing to just above the last byte of RAM.

Previously, stack started pointed to last byte of RAM (eg 0x2001ffff)
and so was not 8-byte aligned.  This caused a bug in combination with
alloca.

This patch also updates some debug printing code.

Addresses issue #872 (among many other undiscovered issues).

Damien George b92cbe6129 py: Move definition of mp_sys_exit to core.
sys.exit always raises SystemExit so doesn't need a special
implementation for each port.  If C exit() is really needed, use the
standard os._exit function.

Also initialise mp_sys_path and mp_sys_argv in teensy port.

Damien George b63be37be1 stmhal: In safe mode, still mount SD card and present as MSD over USB.
It's still "safe" because no scripts are run.  Remove the SD card if you
want to access the internal flash filesystem.  Addresses issue #616.

Also: remove obsolete pyb.source_dir setting, and reset pyb.main and
pyb.usb_mode settings on soft-reset.

Damien George ccacdf44b6 stmhal: Clean up reset/soft-reset code; fix bug init'ing VCP exc.
Make a clearer distinction between init functions that must be done
before any scripts can run (xxx_init0) and those that can be safely
deferred (xxx_init).

Fix bug initialising USB VCP exception.  Addresses issue #788.

Re-order some init function to improve reliability of
reset/soft-reset.

Damien George 8dbbbbc793 Put call to qstr_init and mp_init_emergency_exc_buf in mp_init.
qstr_init is always called exactly before mp_init, so makes sense to
just have mp_init call it.  Similarly with
mp_init_emergency_exception_buf.  Doing this makes the ports simpler and
less error prone (ie they can no longer forget to call these).

Damien George 65dd7bc13d stmhal: Change 0:/ and 1:/ to /flash and /sd; add CWD support.
Some important changes to the way the file system is structured on the
pyboard:

1. 0: and 1: drive names are now replaced with POSIX inspired
directories, namely /flash and /sd.

2. Filesystem now supports the notion of a current working directory.
Supports the standard Python way of manipulating it: os.chdir and
os.getcwd.

3. On boot up, current directory is /flash if no SD inserted, else /sd
if SD inserted.  Then runs boot.py and main.py from the current dir.
This is the same as the old behaviour, but is much more consistent and
flexible (eg you can os.chdir in boot.py to change where main.py is run
from).

4. sys.path (for import) is now set to '' (current dir), plus /flash
and /flash/lib, and then /sd and /sd/lib if SD inserted.  This, along
with CWD, means that import now works properly.  You can import a file
from the current directory.

5. os.listdir is fixed to return just the basename, not the full path.

See issue #537 for background and discussion.

Dave Hylands 5b7fd20fea Add support for storing args during an exception raised by an irq.
The user code should call micropython.alloc_emergency_exception_buf(size)
where size is the size of the buffer used to print the argument
passed to the exception.

With the test code from #732, and a call to
micropython.alloc_emergenncy_exception_buf(100) the following error is
now printed:
```python
>>> import heartbeat_irq
Uncaught exception in Timer(4) interrupt handler
Traceback (most recent call last):
  File "0://heartbeat_irq.py", line 14, in heartbeat_cb
NameError: name 'led' is not defined
```

Damien George 951ed9d02f stmhal: Fix REPL printing by cooking output sent to stdout_obj.
Recent changes to builtin print meant that print was printing to the
mp_sys_stdout_obj, which was sending data raw to the USB CDC device.
The data should be cooked so that \n turns into \r\n.

Paul Sokolovsky 8a96ebea75 py: Move stack_ctrl_init() to mp_init().
As stack checking is enabled by default, ports which don't call
stack_ctrl_init() are broken now (report RuntimeError on startup). Save
them trouble and just init stack control framework in interpreter init.
