diy机器油门不受控自动上升，求大佬帮忙
本帖最后由 darcy 于 2023-4-25 21:15 编辑如下gif所示，我摘掉了电机供电，保留了信号线和接地，只演示了异常状态。
bf diff all配置如下。只要轻轻拨动油门，就会不断的自动增长
硬件：主板stm32F411cue，固件版本4.2.10（4.4不工作），遥控tx12，sbus mini R1V2接收机，使用ULN2003反转sbus信号，3.3v反转供电，主供电minni360 12v-5v dc-dc，3s锂电，6050加速度传感器
加速正常，手动（非遥控）控制油门正常，接收机正常
实在是想不出原因，求大佬解救，谢谢了！！！

另外所有需要接地的地方我都接地了，没浮空，想不明白。。。5555555555555 darcy 发表于 2023-4-25 21:34

桨叶没装，还说装了，等你装了飞就知道了，一切正常 永不炸鸡 发表于 2023-4-27 10:36
桨叶没装，还说装了，等你装了飞就知道了，一切正常
桨叶故意没装的，电机我也上电测试了，就是会不受控的缓慢增加转速。
已经手动模式了headfree，应该是不受加速度传感器影响。
所以就算装了去飞应该也是一个情况（PB4-7引脚pwm就是在增加，装不装桨叶不会影响控制板的pwm输出，且我尝试隔离了主控与电调的供电，排除了电机导致的供电不稳） 装上桨叶应该就好了，是正常的。不明白为什么那么多人爱这样测试，能测出什么来？ headfree是手动模式？？？？？？？？
