MicroPython移植
1.目標板
stm32f407zgt6
2.下載移植準備
micropython源碼
arm交叉編譯工具
sudo apt-get install git
sudo apt-get install gcc-arm-none-eabi
mkdir MicroPython
cd MicroPython
git clone https://github.com/micropython/micropython
cd micropython/mpy-cross
make
cd ../ports/stm32/boards
cp -r STM32F4DISC/ myboard
gedit myboard/mpconfigboard.h #修改#define MICROPY_HW_BOARD_NAME "myboard"
cd ..
gedit Makefile #修改BOARD ?= myboard
make #自動下載需要的庫
編譯成功:

GEN build-myboard/firmware.dfu
GEN build-myboard/firmware.hex
使用jflash燒寫build-myboard/firmware.hex到目標板
3.目標板的基本硬件配置

重新編譯生成hex
4.extmod裁剪
裁剪re,json,zlib等模塊可以通過修改mpconfigport.h文件中相關宏實現
5.後續
後續準備移植LCD
