Arduino_STM32/STM32F3

STM32F3 files have been supplied by Frank-Michael Krause.

The API is not as up to date as in the STM F103 files. It looks like this port is as the F103 files orginally were when I started work on the project. The API is for pre- Arduino 1.0 and doesn't include a lot of functions in the 1.0 API, and the class inheritance will be different in a number of places, most importantly in the Serial class. Specifically Stream.cpp / .h are not present in this port.

-------------------- Details from Frank-Michael ----------------------------

This port of libmaple for Arduino-IDE is based on the inofficial F3 branch of libmaple found on https://github.com/ventosus/libmaple/tree/F3 and supports at the moment the STM32F3Discovery board with programming via ST-link. Linker is configured for linking to flash, not to RAM

Changes by Frank-Michael Krause (mich dot krause at web dot de):

• renaming some stm32f3 related files because the Arduino build system copy all objects to same directory so the source file names must be different
• selected the correct startup modules and linker scripts for board variant stm32f3discovery

Notes:

• the pin names as noted on stm32f3discovery board (PA0, PA1, ..., PF10) can be used as pin id

• usb is untested because I haven't used it really

• There are some libraries and examples related to the STM32F3discovery board. They are commented mostly in german only because I wrote them for use at robotic club of a secondary school and the kids like to have the documentation in german.

  gyro: Interface library for the gyro-chip of the stm32f3discovery, setup the gyro in FIFO mode and so requiring update calls only every < 120ms lsm303: Interface library for Acceleration sensor of the stm32f3discovery, magnetometer not yet supported (writing this driver is currently under work by a student at school) ringbuffer: Class impelentig a ringbuffer with functions for adding time stampes per added element, averaging functions, accessing the stored data like an array roboter: several functionalities needed to program a robot: - dc motor control as known from Lego NXC language - support for HC-SR04 ultrasonic sensors driven by interrupt or blocking direct measurement - function timers based on timer interrupt - modul for interfacing a 24Cxx I2C eeprom chip
