README
------------------------------------------------------------------------------

The libopenstm32 project aims to create an open-source firmware library for
STM32 microcontrollers.

It is written completely from scratch based on the STM32 datasheets,
programming manuals, and application notes. The code is meant to be used
with a GCC toolchain for ARM (arm-elf or arm-none-eabi), flashing of the
code to an STM32 device can be done using the OpenOCD ARM JTAG software.


Status and API
--------------

The libopenstm32 project is currently work in progress. Not all subsystems
of the STM32 are supported, yet.

IMPORTANT: The API of the library is NOT yet considered stable! Please do
           not rely on it, yet! Changes to function names, macro names etc.
           can happen at any time without prior notice!

Building
--------

 $ make

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


Example projects
----------------

The library ships with a few small example projects which illustrate how
individual subsystems of the SMT32 can be configured and used with
libopenstm32.

For flashing the 'miniblink' example (after you built libopenstm32 and the
examples by typing 'make' at the top-level directory) you can execute:

 $ cd examples/stm32-h103/miniblink
 $ make flash

The Makefiles of the examples are configured to use a certain OpenOCD
flash programmer, you might need to change some of the variables in the
Makefile if you use a different one.

You can also flash manually like this:

 $ openocd -f interface/jtagkey-tiny.cfg -f target/stm32.cfg
 $ telnet localhost 4444
 > reset halt
 > flash write_image erase foobar.hex
 > reset

Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or
replace "stm32.cfg" with your respective config file. Replace "foobar.hex"
with the file name of the image you want to flash.


Installation
------------

 $ make install

This will install the library in /usr/local. If you want to install it
elsewhere, use the following syntax:

 $ DESTDIR=/opt make install
