micropython编译流程

最近终于都考完了，虽然最近没有发帖子，可是还是看了挺多东西的，都不深，就自己写一点自己做的工作。

git上面下载了micropython源码 这里就不留地址了，因为下下来还是需要改很多，，虽然我也不知道为什么还有不对的地方，可能环境不太相同，可能是我README没有看仔细。

//下载了 micropython源码，其中不包含其子项目，也就是你要应用在micropython在哪个环境中，那个对应环境的HAL或者是底层库没有包括其中，需要你自己下载 。README中有详细介绍。

/////////////////////没手动下载stm32lib之前的错误   git之后无stm32的lib

Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.

stm32f4xx_hal_dma.h文件  691行
添加
uint32_t DMA_CalcBaseAndBitshift(DMA_HandleTypeDef *hdma);//dd add


stm32f4xx_hal_dma.c文件
DMA_CalcBaseAndBitshift函数的 static去掉


编译成功
虽然现在还没有成功下进去 ，不过我感觉快了。
欢迎指正
