#Environment ##STM32 on QEMU In your workspace of this project(currently, workspace/freertos-basic), please get stm32_p103_demos and qemu_stm32 first.

git clone git://github.com/beckus/stm32_p103_demos.git || git clone https://github.com/beckus/stm32_p103_demos.git 
git clone git://github.com/beckus/qemu_stm32.git || git clone https://github.com/beckus/qemu_stm32.git

cd qemu_stm32
git submodule update --init dtc || sudo apt-get install libfdt-dev
./configure --disable-werror --enable-debug \
    --target-list="arm-softmmu" \
    --extra-cflags=-DSTM32_UART_NO_BAUD_DELAY \
    --extra-cflags=-DSTM32_UART_ENABLE_OVERRUN \
    --disable-gtk
make

#Run Emulation

1. make
2. make qemu

#Visualization

In this project, we adopt Python visualization library - matplotlib to implement profiling visualization such as context switch, interrrupt latency, system call overhead ...etc. Currently, some python modules for visualization are available in directory "visualizer". No matter you use python <module>.py(if log file exists) to run visualizer or use make qemuauto to run emulation and visualizer, you should install matplotlib first. You can use pip install matplotlib or follow the instruction here to skin a cat.

* context switch
* interrupt latency
* system call overhead
