You will need to include stm32f10x.h, stm32f10x_usart.h, and uart.h
in your main.c file
You should copy and modify the Makefile from the BlinkingLight
directory. You should add uart.o and stm32f10x_usart.o to the OBJS list
of project files. You may need to modify the variable TEMPLATEROOT to point
to the directory containing the Demo program.
