Damien George bff1ff28ee stmhal: Fix bug where negative delay/udelay lead to huge delays.
A negative ms/us is now treated as a delay of 0 ms/us.  This patch also
improves the calibration of udelay.

Damien George 5874c1c92b stmhal: Remove #include <stdint.h> from mpconfigport.h.
Make include dependencies neater, and adheres to the coding convention
that headers should not include headers.

Damien George 8d09640b22 stmhal: Add documentation in comments, and script to generate HTML.
Decided to write own script to pull documentation from comments in C code.
Style for writing auto generated documentation is: start line with ///
and then use standard markdown to write the comment.  Keywords
recognised by the scraper begin with backslash.  See code for examples.

Running: python gendoc.py modpyb.c accel.c adc.c dac.c extint.c i2c.c
led.c pin.c rng.c servo.c spi.c uart.c usrsw.c, will generate a HTML
structure in gendoc-out/.

gendoc.py is crude but functional.  Needed something quick, and this was
it.

Damien George 6d3c5e4301 Add ARRAY_SIZE macro, and use it where possible. 2014-04-26 10:47:29 +01:00
Damien George 6125ba4a7f stmhal: Make switch a class, to follow suit of all other modules.
Instead of pyb.switch() as a function, it's more consistent (with
respect to all the other modules and peripherals) to have
pyb.Switch() create a switch object.  This then generalises to having
multiple switches.  Call the object to get its state.  Use sw.callback
to set the callback function for when the switch is pressed.

Damien George 7fdfa93700 stmhal: Add Timer class: simple TIM control, incl callback on IRQ.
Simple but functional timer control.  More sophistication will
eventually be added, or for now just use direct register access :)

Also added pyb.freq() function to get MCU clock frequencies.

Damien George 7533700393 stmhal: Rename USART to UART.
It's really a UART because there is no external clock line (and hence no
synchronous ability, at least in the implementation of this module).
USART should be reserved for a module that has "S"ynchronous capabilities.

Also, UART is shorter and easier to type :)

Damien George d689430e79 stmhal: Add SPI class.
Also some updates to compile with latest changes to core py.

Damien George 6e44381cce stmhal: Improve RTC class; make fatfs use RTC for time stamping files. 2014-04-19 02:17:30 +01:00
Damien George ed5117f6a8 stmhal: Add pyb.unique_id, to get unique id of MCU. 2014-04-19 01:28:18 +01:00
Damien George 44ee42de50 stmhal: Rename pyb.Led to pyb.LED to conform to naming rules.
It's Light Emitting Diode, so should be LED.

Damien George 8cf08a58a1 stmhal: Remove pyb.input (use sys.stdio.read(1) instead). 2014-04-19 00:50:50 +01:00
Damien George a8f5d15fc6 stmhal: Update help and comments re gpio changing to Pin. 2014-04-18 22:48:59 +01:00
Damien George c66d86c5ce stmhal: Big cleanup; merge gpio into Pin; make names consistent.
This is an attempt to clean up the Micro Python API on the pyboard.
Gpio functionality is now in the Pin object, which seems more natural.
Constants for MODE and PULL are now in pyb.Pin.  Names of some
classes have been adjusted to conform to CamelCase.  Other
miscellaneous changes and clean up here and there.

Damien George f6be480bda stmhal: Add pyb.have_cdc function to check if USB CDC device is enabled. 2014-04-16 15:52:50 +01:00
Damien George 6dba016a56 stmhal: Add pyb.wfi() function (calls __WFI). 2014-04-14 01:45:24 +01:00
Damien George 0aab675108 stmhal: Little hack to dump GC allocation table using pyb.info().
Pass a single parameter (doesn't matter what): pyb.info(1), will dump
the GC alloc table.

Damien George 8b0535e23f py: Change module globals from mp_map_t* to mp_obj_dict_t*.
Towards addressing issue #424.

Had a small increase to ROM usage (order 60 bytes).

Damien George df6567e634 Merge map.h into obj.h.
Pretty much everyone needs to include map.h, since it's such an integral
part of the Micro Python object implementation.  Thus, the definitions
are now in obj.h instead.  map.h is removed.

Damien George 038df43183 stmhal: Implement selector for USB device mode; improve boot up.
Can now choose at boot up whether the USB device is CDC+MSC or CDC+HID.
Choice is made by an option in boot.py, with default being CDC+MSC.
HID+MSC is not currently supported, but should be easy to implement.

Boot up now has ability to change the reset mode: hold down USR switch
while booting and LEDs will count from 1 to 7 to indicate the boot mode.
Release USR when correct mode is selected.  Current modes are 1 (normal
boot), 2 (safe mode), 3 (reset FS mode).

Damien George 64563e39b3 stmhal: Add CDC+HID USB device.
The HID device must appear before the CDC in order for both to work at
the same time.

Whilst the code is working, it's not currently used.

Damien George c9fd6645b0 stmhal: Factor out stdio and readline to separate files.
Adds readline_init() to clear readline history on soft reset.  Addresses
issue #387.

Damien George 6cfda3084d stmhal: Add I2C support; change accel driver to use new I2C. 2014-03-25 23:26:14 +00:00
Damien George caac542b23 Proper support for registering builtin modules in ROM.
Comes with some refactoring of code and renaming of files.  All modules
are now named mod*.[ch].
