f6be480bda stmhal: Add pyb.have_cdc function to check if USB CDC device is enabled. 2014-04-16 15:52:50 +01:00

4d7f4eb6a9 stmhal: Add ADC function to read data at a given frequency.
Reads ADC values into a bytearray (or similar) at a fixed rate.  Needs a
better name and improved API.  Also fix up DAC dma function (which also
needs a better name and API).

e95da5b784 stmhal: Add I2C.scan method, to scan all devices on the bus.
Simple way to find the address of an attached I2C device.

3f4898456b stmhal: Add stm module, which contains some constants for the MCU.
Also contains raw memory read/write functions, read8, read16, read32,
write8, write16, write32.  Can now do:

stm.write16(stm.GPIOA + stm.GPIO_BSRRL, 1 << 13)

This turns on the red LED.

With the new constant folding, the above constants for the GPIO address
are actually compiled to constants (and the addition done) at compile
time.  For viper code and inline assembler, this optimisation will make
a big difference.  In the inline assembler, using these constants would
not be possible without this constant folding.

72d70cb045 unix, stmhal: Consistently use "FileIO" as class name for file objects.
They correspond to io.FileIO in io module hierarchy (with small caveat
that io.FileIO is raw file and works with bytes, not strings).

27e735fd18 py: Replace stream_p with *stream_p in mp_obj_type_t.
This is to reduce ROM usage.  stream_p is used in file and socket types
only (at the moment), so seems a good idea to make the protocol
functions a pointer instead of the actual structure.

It saves 308 bytes of ROM in the stmhal/ port, 928 in unix/.

1d4d9ddd9e stmhal: Reimplement file support using stream protocol API.
This adds readline(), readall(), etc. methods. Also other fixes to make
Python API compliant and "with" support.

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).
