【GE32E231_DIY】FreeRTOS+DAP_RTT+多功能按键+USART_DMA再加入FREEMODBUS

<p>FreeRTOS+DAP_RTT+多功能按键+USART_DMA再加入FREEMODBUS</p>

<p>到这里，项目一步一步实现了，一步一步调试真不容易。感谢家人的支持，成有时间码代码。</p>

<p></p>

<p>freemodbus主要思想是用状态机实现，发送&mdash;中断。接收&mdash;中断,硬时间确认，加一轮询</p>

<p>int main(void)<br />
{<br />
&nbsp;&nbsp; &nbsp;systick_config();<br />
//&nbsp;&nbsp; &nbsp;button_enable();&nbsp;<br />
//&nbsp;&nbsp; &nbsp;CreateSoftwareTime();<br />
&nbsp;&nbsp; &nbsp;LED_Init();<br />
&nbsp;&nbsp; &nbsp;eMBInit(MB_RTU, 0x01, 1, 115200, &nbsp;MB_PAR_NONE);//初始化Freemodbus数据，定时器，串口（包括中断），工作装态<br />
&nbsp;&nbsp; &nbsp;eMBEnable(); //启动接收中断，等待串口数据到来<br />
&nbsp;&nbsp; &nbsp;/* Create tasks. */<br />
&nbsp;&nbsp; &nbsp;prvCreateTasks();<br />
&nbsp;&nbsp; &nbsp;NVIC_SetPriority_Init();<br />
&nbsp;&nbsp; &nbsp;NVIC_EnableIRQ_Init();<br />
//&nbsp;&nbsp; &nbsp;TIMER2_Config();<br />
&nbsp;&nbsp; &nbsp;/* Start scheduler. */<br />
&nbsp;&nbsp; &nbsp;vTaskStartScheduler();<br />
&nbsp;&nbsp; &nbsp;/* Will not get here if the scheduler starts successfully. &nbsp;If you do end up<br />
&nbsp;&nbsp; &nbsp;here then there wasn&#39;t enough heap memory available to start either the idle<br />
&nbsp;&nbsp; &nbsp;task or the timer/daemon task. &nbsp;https://www.freertos.org/a00111.html */<br />
&nbsp;&nbsp; &nbsp;for( ; ; )<br />
&nbsp;&nbsp; &nbsp;{<br />
&nbsp;&nbsp; &nbsp;}</p>

<p>}</p>

<p>&nbsp;</p>

<p>非常感谢楼主的提供，E231应该和E230没什么区别吧？放到230应该可以直接运行~~我猜</p>
