Alexander Steffen 55f33240f3 all: Use the name MicroPython consistently in comments
There were several different spellings of MicroPython present in comments,
when there should be only one.

Alexander Steffen 71173cd57d cc3200: Use the name MicroPython consistently in code.
In a few places the cc3200 port uses the incorrect spelling Micropython
instead of MicroPython.

Damien George 29551ba566 cc3200: Move stoupper to ftp.c and define in terms of unichar_toupper.
ftp.c is the only user of this function so making it static in that file
allows it to be inlined.  Also, reusing unichar_toupper means we no longer
depend on the C stdlib for toupper, saving about 300 bytes of code space.

Damien George 56506fd64a cc3200: Convert to use new VFS sub-system and new ooFatFs library. 2017-01-30 12:26:07 +11:00
Damien George bfa948c0a5 cc3200: Add implementations of mp_import_stat and builtin_open.
They disappeared when stmhal changed to use new MICROPY_VFS code.

Damien George 469c623bb8 cc3200: Shrink the FreeRTOS heap and place TCB+stack in freed location.
The 16k FreeRTOS heap originally had all TCBs and stacks dynamically
allocated within it (plus semaphores and some other things).  Now that
xTaskCreateStatic is used instead of xTaskCreate, the TCBs and stacks
are allocated statically and no longer use any of the FreeRTOS heap.
Therefore, the FreeRTOS stack can be shrunk by the amount that has been
made static.  Furthermore, the TCBs and stack that are now static should
be placed in the .rtos_heaps section of RAM because this RAM is treated
specially by the bootloader (the bootloader executes from the first 16k
of RAM and loads the firmware into the section starting after the 16k).

After this patch the FreeRTOS heap (ucHeap) is 7200 bytes.  The memory
available for the MicroPython heap is 54936 bytes (including GC overhead).

Damien George 0455755296 cc3200: Use xTaskCreateStatic instead of osi_TaskCreate.
This allows to statically allocate the TCB (thread control block) and
thread stack in the BSS segment, reducing the need for dynamic memory
allocation.

Damien George eef4f13a33 cc3200: Add basic threading capabilities.
Can create a new thread and run it.  Does not use the GIL at this point.

Damien George 9b1c1262dc cc3200: Define our own FreeRTOS heap so it can go in a special segment. 2016-06-28 11:28:50 +01:00
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.

Daniel Campora 491c321720 cc3200: Re-config antenna selection when waking from suspended mode. 2015-06-07 13:28:47 +02:00
Daniel Campora a3acaa000c cc3200: Add antenna selection feature to WLAN. 2015-06-07 00:06:27 +02:00
danicampora 26cbc91373 cc3200: Place functions only used while booting in a special section.
Such functions are never used after MicroPython has started, and they
remain in RAM wasting space. Now they are placed in a special section
named "boot" which sits just before the heap, allowing us to extend
the effective heap area up to the new boot section. Right now, this
gives us back ~1K, but in the future, more functions might end up in
there as well.

danicampora d01060241a cc3200: Add heartbeat signal on system led. 2015-02-28 19:03:21 +01:00
danicampora 7a074a14ce cc3200: Implement safe boot pin and system led behaviour.
The safe boot pin, when pulled high during reset rolls back the
firmware to the "factory" image and skips execution of 'boot.py'
and 'main.py'. This is useful to recover from a crash condition.
The system led is used mostly to signal errors.

danicampora 11aa6ba456 cc3200: Add WDT functionality as part of the pyb module.
Also improve pybsd, and make it save it's pin configuration.
This is a necessary step towards supporting the CC3200 low
power deep sleep (LPDS) mode.

danicampora 33ddb566a7 cc3200: Remove dependencies from FreeRTOS.
Use the simplelink wrappers instead. This is one step further
towards having a single module for the cc3200 and the cc3100.

Damien George 4a23a01945 cc3200: Add explicit py/ path-prefix for py includes.
This is how it should be, so one knows exactly where the includes are
coming from.

danicampora 8785645a95 cc3200: Add cc3200 port of MicroPython.
The port currently implements support for GPIO, RTC, ExtInt and the WiFi
subsystem. A small file system is available in the serial flash. A
bootloader which makes OTA updates possible, is also part of this initial
implementation.
