$50.006. 简易单圈角度控制
6.1. 简介
- 通过指令控制指定 ID 的舵机 (或全部舵机) , 在设定的 运动时间 内移动至 目标位置 (±180°) , 并可设定 执行功率。
- 指令编号 : 08 (0x08)
6.2. 指令
| 字节名 | 长度 | 数据类型 | 说明 |
|---|---|---|---|
header |
2 | uint16_t | 固定标识 (0x12 0x4c) |
cmd_id |
1 | uint8_t | 简易单圈角度控制(0x08) |
length |
1 | uint8_t | 7个字节 (0x07) |
servo_id |
1 | uint8_t | 舵机 ID, 范围 0 ~ 254 (0x00 ~ 0xfc ) 0xff 为线上所有舵机 |
position |
2 | int16_t | 目标位置, 单位: 0.1° 范围 : +1800 ~ -1800 (+CW / −CCW) |
time |
2 | uint16_t | 运动时间, 单位: ms |
power |
2 | uint16_t | 执行功率, 单位mW 若power=0, 或大于功率保护阈值, 则都按照功率保护阈值执行 |
checksum |
1 | uint8_t | 校验码 = Σ(Byte[0..10]) % 256 |
0x12 0x4c 0x08 0x07 0x00 0x84 0x03 0xf4 0x01 0x00 0x00 0xe9
示例说明 :
- 设置 ID 0 舵机,
- 在 500ms 内移动到目标位置 +90°,
- 将
功率保护阈值配置参数设置为最大执行功率, 以 最大功率 运行。
6.3. 响应 (可选)
| 字节名 | 长度 | 数据类型 | 说明 |
|---|---|---|---|
header |
2 | uint16_t | 固定标识 (0x05 0x1c) |
cmd_id |
1 | uint8_t | 简易单圈角度控制(0x08) |
length |
1 | uint8_t | 2个字节 (0x02) |
servo_id |
1 | uint8_t | 舵机 ID, 范围 0 ~ 254 (0x00 ~ 0xfc ) |
result |
1 | uint8_t | 0x01: 执行成功 | 0x00: 失败 |
checksum |
1 | uint8_t | 校验码 = Σ(Byte[0..5]) % 256 |
0x05 0x1C 0x08 0x02 0x00 0x01 0x2c
示例说明 :
- ID 0 舵机返回的值为 0x01, 代表 执行成功。
注意 : 默认没有响应包, 仅当上位机设置舵机配置参数指令送出响应开关= 是, 才会回传。
