Damien George	f20e093b9b	stmhal: Add lots of constants to stm module.	11 years ago
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.	11 years ago
Damien George	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.	11 years ago

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.

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.
