概述
看了稚晖君的Dummy机械臂视频后,再一次激发自己做点小玩意,嗯,会动,有显示,有声音,远程能控制。。。,想想做完大抵如此,复刻机械臂?成本有点高,和大佬差距还是有的,至少我不会solidworks,放弃吧。缘于学校里做的智能小车是直流电机驱动,驱动和控制简单,无刷电机没玩过,要不玩一通?说干就干。
看了些资料,感觉odrive是不错的选择,于是阅读了些3.5版本的硬件设计,也着手学习cadence,终于画了一版,下载git fw-v0.5.1版本,烧写下去,玩了起来。
Odrive 体验
后来将odrive 通讯类代码抠掉了,毕竟嵌入式产品这种可视化通讯很少,以备将来项目要用,用核心部分即可。
以上是odrive核心底层关系图,听说simpleFoc也不错,正好有这个主板,那就将simpleFoc也了解一下吧,看了下源码,用了什么鬼arduino,这就更驱使本人想移植到gcc下,复刻了下odrive的编译框架,开始移植起了simpleFoc了,看了里面有许多print函数,准备一个个用printf替代,改起来有点麻烦,索性将print文件准备好吧。
