C#-NetDuino-串行

问题描述

你好

我需要一些代码帮助，因为我一直在重新排列它并添加内容并使用try，catch，但是无论我尝试什么，我都无法使串行与Netduino上的伺服/PWM一起使用.

此代码将写入Netduino，并且Netduino将对串行作出响应，但是一旦冻结，它就会冻结.

请任何帮助将不胜感激.

谢谢

代码:

Hello

I need some help with my code because i keep re-arranging it and adding stuff and using try, catch but no matter what i try i cannot get the serial to work with a servo / PWM on Netduino.

This code writes to the Netduino and the Netduino responds on serial but as soon as the while begins it freezes.

Please any help would be appreciated.

Thanks

Regards
Mitchell
