//! 单电机验证工具:让一个 C620 / GM3508 转起来,验证电机抽象全链路。
|
||
//!
|
||
//! ```sh
|
||
//! socketcan-spin [interface] [esc_id] [rotor_rpm] [duration_secs]
|
||
//! # 例:can0 上电调 1 以 1000 rpm(转子)转 10 秒
|
||
//! cargo run --release -p chassis-bench --bin socketcan-spin -- can0 1 1000 10
|
||
//! ```
|
||
//!
|
||
//! 关键点在 `spin_one`:它只依赖 `motor_core::Motor` 抽象,完全不知道
|
||
//! 背后是 C620 协议还是别的电机——换任何实现该 trait 的电机,这段代码
|
||
//! 原样可用。抽象与协议实现(`dji-esc`)、总线后端(`dji-esc-socketcan`)在此汇合。
|
||
//!
|
||
//! 仅 Linux(需要 SocketCAN);其他平台编译为报错桩。
