我查找了很多迪文论坛的程序，工程主体采用的是：【OS用户核应用】T5L屏串口2、3、4、5的82、83协议C语言 - T5L ASIC开发 - 迪文科技论坛 - Powered by Discuz!
我使用uart2-modbus-ASCII来与下位机通讯。我找了论坛里好多的例程，发现好像没有使用状态机方式的程序。麻烦官方帮我解答一下。
- 程序设计思路：我想按照状态机的方式来写程序，在Read_0xF00()获取屏幕按键，然后在while(1)来处理程序，主要就是发modbus指令到下位机。实现的是在0~6分钟内下位机两种灯闪烁，6~7分钟中内下位机灯常亮。
- 现象：我在AmblyProcess函数中的Process_INIT中，如果写了ProcessWorkStatus = Process_WORKONE，modbus就不发送。注释掉ProcessWorkStatus = Process_WORKONE;就能一直发送(因为没有切换状态)。现象感觉是我还没有发完，就切换了状态。
- 问题：我看了好多程序，好像没有在while(1)使用状态机来实现的，请问我需要注意些什么？或者说有没有相关的例程我可以借来参考？要不就是我不应该使用这种方式来实现？
