USART1 polling mode TX/RX verify for STM32F429I Discovery

stm32f429-usart1

The program for Verify STM32F429I Discovery USART1 on PORTA

Build instructions

prepare, you need download and build somthing tools

1. STM32F429I-Discovery Firmware - STM32F429 Library
2. Stlink - Flash tools
3. GCC for ARM Embedded - Toolchain
   currently on Linux(Ubuntu) use gcc 4.8.2 2014q1

a demo step like the following

#
# create a folder
#
mkdir -p stm32f429
cd stm32f429
#
# Download STM32F429I-Discovery Firmware
# url:http://www.st.com/web/en/catalog/tools/PF259429
#
wget http://www.st.com/st-web-ui/static/active/en/st_prod_software_internet/resource/technical/software/firmware/stsw-stm32138.zip
unzip stsw-stm32138.zip
#
# get stlink source code & build
# url: https://github.com/texane/stlink
#
mkdir -p utils
cd utils
git clone https://github.com/texane/stlink.git
cd stlink
./autogen.sh
./configure
make
cd ..
mkdir -p bin
cd bin
cp -vf ../stlink/st-flash .
cp -vf ../stlink/st-info .
cp -vf ../stlink/st-term .
cp -vf ../stlink/st-util .
cd ..
cd ..
#
# download prebuilt toolchain
