四周年庆-【赚周年币】fireduino-基于labview的双机通信-系统调试-爱板网论坛 - 电子工程师学习交流园地 https://www.cirmall.com/bbs/thread-59347-1-1.html
准备做一个如下功能的东西
要求:温度传感器检测到某一温度警戒值,触发单片机控制摄像头开始拍摄视频15s,然后存储至存储设备(SD卡或U盘),然后通过蓝牙将视频传输至手机。可以不涉及视频压缩技术。
为什么不直接把视频考到手机呢?因为我想发朋友圈,比如说当我朋友圈看到soso同学更新状态时,我也更新,发一条状态,紧随其后,表示和她的形影不离。
目前摄像使用OV7670,一直想试用arduino due,但是未能如愿,这个板子一直没到手。于是想到了之前的fireduino,两个32位的MCU PK下,
due使用ATSAM3X8EA,参数如下

同系列比较
fireduino使用Rockchip NanoD处理器,关于它的介绍详见下面帖子,都是M3内核

虽然fireduino是双核,但是fireduino引出的引脚着实不多,总有一种感觉:Rockchip NanoD似乎没有SAM3X强
这个项目能做多少做多少,加油 |
