<p style="text-align:justify"><span style="font-size:16px;"><span style="font-family:&quot;Times New Roman&quot;,serif"><b><span style="background:white"><span style="font-family:&quot;微软雅黑&quot;,&quot;sans-serif&quot;">&nbsp; &nbsp; 1、项目背景</span></span></b></span></span></p>

<p style="text-align:justify"><span style="font-size:16px;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;在进行产品测试中,经常需要看CAN通信上指定ID的数据,有时需要使用PC上位机或CAN卡来监测数据,在有些环境下使用,携带PC不是很方便,通过此次活动使用RVB2601板卡设计小型便携的小型LCD终端,可以实时监测要查看的数据。</span></p>

<p style="margin-left:28px; text-indent:21.0pt; text-align:justify">&nbsp;</p>

<p style="text-align:justify"><span style="font-size:16px;"><span style="font-family:&quot;Times New Roman&quot;,serif"><b><span style="background:white"><span style="font-family:&quot;微软雅黑&quot;,&quot;sans-serif&quot;">&nbsp; &nbsp; 2、作品简介</span></span></b></span></span></p>

<p style="text-align:justify"><span style="font-size:16px;"><span style="font-family:&quot;Times New Roman&quot;,serif"><span style="font-family:&quot;微软雅黑&quot;,&quot;sans-serif&quot;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;作品是在RVB2601板卡的基础上扩展了CAN通信和I2C扩展IO口芯片,实现外部CAN通信收发和按键的输入,可以扩展按键来操作LCD界面,实现人机交互显示。同时在外部增加了一路DCDC电源,可以适配外围设备给板卡供电,实现DC6-24V宽电压供电。电路图上预留一些跳线,是考虑到板卡引脚的功能复用,可以根据应用板卡的功能,来跳选引脚。</span></span></span></p>

<span style="font-size:16px;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<strong>&nbsp; 4、各部分功能说明和解析</strong></span></p>

<p><span style="font-size:16px;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;程序部分各功能如下:<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.1、主程序</span></p>

<p><span style="font-size:16px;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;创建信号量和两个线程。</span></p>

<p><span style="font-size:16px;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.2、线程1&nbsp;<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;线程1,用于处理CAN接收的数据,处理后,发送信号量给线程2,处理显示。</span></p>

<p><span style="font-size:16px;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</span></p>

<p><span style="font-size:16px;"><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</strong></span></p>

<p><span style="font-size:16px;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.3、线程2<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;线程2,创建了LVGL显示创口,将接收的数据显示在显示屏上。</span></p>

<p><span style="font-size:16px;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</span></p>

<p>&nbsp;</p>

<p><span style="font-size:16px;">&nbsp; &nbsp; &nbsp; &nbsp; 4.4、CAN通信处理<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;使用中断方式接收CAN数据,</span></p>

<p><br />
<span style="font-size:16px;">&nbsp;&nbsp;&nbsp;&nbsp;项目使用了开发板自带的yoc系统,这个使用中断部分还不是很熟悉,使用了常规的中断处理方式,也能正常工作,但觉得这种中断处理方式不是最优的选择。</span></p>

<p>扩展板画的很专业 刚开始看代码还在想CAN怎么用的GPIO中断 仔细看原理图原来用的MCP2515</p>

牛人牛人,看来你是最用心的人之一,希望得抱得大奖回家!

<p>希望看看can的压力下的稳定性。</p>
