函数体后函数声明“在线：CysISR（MySeId中断）。另外，有很多错误报告时，查看morse_isr C文件。我相信这是简单的东西，我看但我不清楚消息（S），我感觉这是造成项目不正确。然而，这些代码

大家好，我正在制作一个应用程序，它通过Modbus通信到一个设备上，我想检测它们之间是否存在通信丢失，以便激活一个警报。好的，我已经实现了一个带有TMR2的计时器，如果没有20个以上的APROX，就可以激活警报。它可以正常工作，闹钟被激活，但是经过一段时间后，计数器复位，警报被解除，直到另一个20秒的通信丢失。我把代码的碎片留给了我，因为任何人都能告诉我问题是什么，因为我不能用FI。任何感觉…TMR2Y-中断复位到0 TMR2Y计数器，如果我收到任何数据，只有在RXI中断。当计数器复位时，没有RXI中断，我已经证明了。报警管理如果您需要更多信息，不要犹豫问我。希望有人能给我一些启示，因为我疯了…多谢 以上来自于百度翻译 以下为原文 Hi everyone, I am making an application that communicates by MODBUS to a device and I want to detect if there is a loss of communication between them so as to activate an alarm. Ok, i have implemented a timer with TMR2 so as to activate the alarm if there are more than 20 seconds aprox without communication. It works all right, the alarm is activated but after a period of time the counter resets itself and the alarm is desactivated untill another 20s of loss of communication. I left you the fragment of code where I implement this so as anyone could show me what the problem is because i can´t find any sense....

Hope anyone could bring some light to this, because I´m getting mad... Many thanks

想请问一下，这个版本怎么烧程序？我有JTAG的下载线。谢谢各位能花点时间帮我这个菜鸟一下，在网上搜了搜不到所以猜到论坛上来请教的。
