Damien George 3b0fbfe4e5 cc3200/mpthreadport: Properly initialise the main thread's data. 2016-06-28 11:28:52 +01:00
Damien George 27241293c4 cc3200/mpthreadport: Make mutex statically allocated. 
Reduced the need for the FreeRTOS heap to allocate the mutex.

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 c9520c591b cc3200: Fix call to new exception to be _msg instead of _arg1. 2016-06-28 11:28:51 +01:00
Damien George df95f52583 py/modthread: Allow to properly set the stack limit of a thread. 
We rely on the port setting and adjusting the stack size so there is
enough room to recover from hitting the stack limit.

Damien George eef4f13a33 cc3200: Add basic threading capabilities. 
Can create a new thread and run it.  Does not use the GIL at this point.
 2016-06-28 11:28:51 +01:00
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 5c0fc73f33 cc3200: Update FreeRTOS to v9.0.0. 
This is a pristine copy (actually a subset of files) of upstream FreeRTOS
v9.0.0.

Modifications to the previous version of FreeRTOS (v8.1.2) included
addition of __attribute__ ((section (".boot"))) to the following
functions:

    pxPortInitialiseStack
    prvTaskExitError
    prvPortStartFirstTask
    xPortStartScheduler
    vPortSetupTimerInterrupt
    xTaskGenericCreate
    vTaskStartScheduler
    prvInitialiseTCBVariables
    prvInitialiseTaskLists
    prvAllocateTCBAndStack

This attribute will need to be reinstated on a case-by-case basis
because some of the above functions are now removed/changed.

Paul Sokolovsky 07209f8592 all: Rename mp_obj_type_t::stream_p to protocol. 
It's now used for more than just stream protocol (e.g. pin protocol), so
don't use false names.

Damien George 70ff7350e7 stmhal, cc3200: Change i2c.scan() method to scan addresses 0x08-0x77. 
A standard I2C address is 7 bits but addresses 0b0000xxx and 0b1111xxx
are reserved.  The scan() method is changed to reflect this, along with
the docs.

Colin Hogben 104aa26271 cc3200, stmhal, teensy: Use pyhelp_print_obj function. 
Update the help() implementations in the cc3200, stmhal and teensy
ports to use the pyhelp_print_obj function.

Jan Čapek d76c65f599 py: Add rules for automated extraction of qstrs from sources. 
- add template rule that converts a specified source file into a qstring file

- add special rule for generating a central header that contains all
  extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED
  variable. Each platform appends a list of sources that may contain
  qstrings into a new build variable: SRC_QSTR. Any autogenerated
  prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable.

- remove most qstrings from py/qstrdefs, keep only qstrings that
  contain special characters - these cannot be easily detected in the
  sources without additional annotations

- remove most manual qstrdefs, use qstrdef autogen for: py, cc3200,
  stmhal, teensy, unix, windows, pic16bit:

   - remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.)
   - remove all port specific qstrdefs except for special strings
   - append sources for qstr generation in platform makefiles (SRC_QSTR)

Paul Sokolovsky 9b0714b24c py: Declare help, input, open builtins in core. 
These are *defined* per-port, but why redeclare them again and again.

Damien George 6eb17c31a9 ports: Disable async/await on bare-arm, minimal, pic16bit, cc3200. 
It costs 1188 bytes of code on Thumb 2 archs.

danicampora fe9620a2bd test/wipy: Add Timer class tests. 2016-02-21 21:53:20 +01:00
danicampora 73c9f85b4c cc3200: Simplify the Timer API and correct the documents. 
Make the PWM duty cycle configurable from 0.00 to 100.00 by
accepting values from 0 to 10000.
Add automatic Pin assignment when operating in PWM mode.
 2016-02-21 21:53:16 +01:00
danicampora 562bcffd3a cc3200: Improve robustness of the I2C driver. 
When scanning for devices, try reading then writing. Increase the
timeout of the transactions from 10 to 20 ms.
 2016-02-21 21:41:06 +01:00
danicampora ed8db2e371 cc3200: Finally fix the Timer class API. 
Properly calculate the period and the prescaler, this now allows to
set the PWM frequency down to 5Hz. Make Timer IDs go from 0 to 3.
Add the trigger definitions for the channel IRQ.
