This is the first working example code which is tested on hardware. The LED on the Olimex STM-H103 eval board is happily blinking. We use a dummy "delay" function (basically a busy-waiting for-loop), which will only work if you use -O0 in CFLAGS (-O2, -O3, or -Os will not work as the compiler optimizes the loop away). We use some arbitrary value for stack size (2 KB) and use main() directly as the reset vector function. This will change later. Also, we do the GPIO and clock init as well as the GPIO toggling for the LED blinking fully "manually" for now, but there may be more higher-level functions for doing that at some later date.
------------------------------------------------------------------------------ README ------------------------------------------------------------------------------ The libopenstm32 project aims to create an open-source firmware library for STM32 microcontrollers. 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 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 Coding style ------------ The whole library is programmed using the Linux kernel coding style, see http://lxr.linux.no/linux/Documentation/CodingStyle for details. Please use the same style for any code contributions, thanks! License ------- The libopenstm32 code is released under the terms of the GNU General Public License (GPL), version 2 or later. See COPYING for details.
