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 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 cc20482aa9 cc3200: Add method to configure the servers timeout.
With network.server_timeout(secs) the timeout can be changed.
The default value is 300 secs. Minimmum accpeted is 5 secs.
Without params the function returns the current configured timeout.

This is needed to avoid half-open connections.

Matt Anderson 0458833072 cc3200: Make telnet login procedure work with Tera Term.
This is actually a workaround Ter Term's issue of not obeying to the
telnet options that the server is sending. Therefore, we must buffer
chars until either a '\r' or the max length of the username/password
is received.

Daniel Campora 684dba40f0 cc3200: Roll back to the previous telnet and ftp timeouts.
Unfortunately, these timeouts are the only realiable way (for now), to
be able to detect broken connections due to half-open sockets. Such a
thing occurs when getting out of the WiFi coverage area or when
disconnecting from the AP (sometimes the client doesn't send the
disconnect packet).

danicampora f8ee88bbe0 cc3200: Move server methods from WLAN to the network module. 2015-03-19 17:08:25 +01:00
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.
