Piotr Esden-Tempski d7489ebfbd Added standard clock setup routines.

Thanks to Thomas Otto for pointing out problems with the clock code in
examples and his clock routine implementations. Based on that the most
common clock combination routines were added to the library and all
routines in examples setting up the clock replaced with calls to that
functions.

This example program repeatedly sends characters on SPI1 on the ST STM32-based
Olimex STM32-H103 eval board (see http://olimex.com/dev/stm32-h103.html
for details).


Building
--------

 $ make

Running 'make' on the top-level libopenstm32 directory will automatically
also build this example. Or you can build the library "manually" and
then run 'make' in this directory.

You may want to override the toolchain (e.g., arm-elf or arm-none-eabi):

 $ PREFIX=arm-none-eabi make

For a more verbose build you can use

 $ make V=1


Flashing
--------

You can flash the generated code on the STM32-H103 board using OpenOCD:

 $ make flash

Or you can do the same manually via:

 $ openocd -f interface/jtagkey-tiny.cfg -f board/olimex_stm32_h103.cfg
 $ telnet localhost 4444
 > init
 > reset halt
 > flash write_image erase spi.hex
 > reset

Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or
replace "olimex_stm32_h103.cfg" with your respective board config file.
