1. 源由
手边正好有一块AOCODARC H7DUAL的板子,后续也许可以派上用处。
鉴于BetaFlight统一硬件配置文件研读有了一个大概的了解,针对上述板子做一个简单review,并记录澄清一些问题。
2. Review配置

4. 问题汇总
- 问题1:为什么没有配置gyro_2_bustype?
已反馈生厂商或研读代码,待继续跟进。
- 问题2:serial 0配置主要目的是什么,不能默认让用户进行配置吗?
已反馈生厂商或研读代码,待继续跟进。
- 问题3:USB_DETECT有什么特殊用途吗?
a) 目前BetaFlight上没有用到这个引脚的功能。
b) 从精简的角度考虑,可以删除(已经与厂商确认)。
c) 个人认为这个引脚不配置,还可以做其他用途。不知道板子是否引出到GPIO口子上,估计没有。
- 问题4:板子配置文件中dma TIMUP配置主要用途是什么?
已反馈生厂商或研读代码,待继续跟进。
- 问题5:D14和D15的用途是什么?
厂家反馈:S9(D14)和S10(D15)分别对应电机#9和电机#10
但是电机相关的resource/timer/dma相关定义又不全
上述问题汇总,希望大家能指正/纠错,让博主和读者更加了解这些配置项。如有更新信息,会尽快将问题的答案更新上来,请感兴趣的朋友持续关注!
