All #includes now explicitly use the "<libopencm3/stm32/rcc.h>" format. If you want to get rid of the "libopencm3" prefix in your local project you can add a respective -I entry in your Makefile (not recommended though). All .ld files and .a libs are installed in $(TOOLCHAIN_DIR)/lib directly (as before), but are now renamed to avoid potential conflicts now or in the future. Examples: libopencm3_lpc13xx.a libopencm3_lpc13xx.ld libopencm3_stm32.a libopencm3_stm32.ld
------------------------------------------------------------------------------ README ------------------------------------------------------------------------------ This example program sends some characters on USART3 on the ST STM32-based Olimex STM32-H103 eval board (see http://olimex.com/dev/stm32-h103.html for details). The terminal settings for the receiving device/PC are 38400 8n1. The sending is done in a blocking way in the code, see the usart_irq example for a more elaborate USART example.
