PWM输出控制好盈电调时老是提示无油门信号

98675972

我的是战舰版的STM32开发板，用timer3输出4路PWM信号，频率为50Hz，软件仿真时很好，但是当与电调连接后，电调提示无油门信号输出，请问怎么解决，急。

贴代码吧，这样不知道怎么理解你的问题

在MDK的Edit->configuration选项对话框中有ENCODING复选框，在里面设置Chinese GB2312就贴不出乱码了。

我去，你就不能打包么，这样看老半天，你牛

将下图中红色框框的内容按箭头位置放一下看看

你很好

楼主，STM32可以控制好盈电调？可以做四轴？

xinxian

控制电调，需要有两个参数，第一个是频率，第二个占空比。我觉得你是看说明书操作的，我如果是你的话，我会用示波器或者是逻辑分析仪看一下我的代码有没有错误，比如我要输出50的占空比却输出60了。第二个是你的电调有没有被刷过，要是被刷过的话，那你就需要自己去测了，比如从百分之1测试到百分之百
