应用背景The leading developers of Marlin are currently (January 2015) EvdZ and bkubicek, though many others contribute with their patches. This is a firmware for reprap single-processor electronics setups. It also works on the Ultimaker PCB. It supports printing from SD card+Folders, and look-ahead trajectory planning. This work is licensed under the GNU GPL v3 or (at the user"s discretion) any later version. It is based on Sprinter firmware, which was licensed under GPL v2 or later.关键技术 Features: Interrupt based movement with real linear acceleration. High steprate. Look ahead (Keep the speed high when possible. High cornering speed). Interrupt based temperature protection. preliminary sup

本GPS导航系统设计是基于ublox NEO-M8N平台设计的，通过串口通讯和IIC通讯，搜星速度快，可轻松搜星数15颗以上，与MCU通讯十分方便，是目前导航系统中最好的选择！

应用背景本程序是用在一种开关磁阻电机上的，原理图和功能和无刷直流电机基本一样，只是控制策略不一样，应用于电机拖动，开关磁阻电机价格便宜，但需要配套的控制器关键技术本程序是在网上下载后应用到实际项目中，由于公司规定不能传源码，只有上传部分代码，包含位置检测，速度检测，PID运算，读者可自行修改为自己的程序，另外关键代码都有注释，方便理解

这是bios-lt的最新板，(1) bios.img占用的扇区数由4个合并为2个,相应的文件大小由193K减小为66K (2) 实现了对FLASH芯片BOOT扇区的处理,建立FLASH分区时不用再考虑让开BOOT扇区 改动的主要目的是想做到: 在29F040上空出384K的空间,建立一个分区存放不含应用程序的uClinux kernel, 将29LV160作为一个大分区,在其上建立JFFS2文件系统,并挂接为uClinux的根文件系统. 系统应用程序全部存储在JFFS2文件系统中. 再使用tmpfs来做临时目录和 /var目录. 这样就可以做到建立一个更加通用的,拿来就可以运行的uClinux系统,相当于给开发版 预装一个操作系统^_^ 由于JFFS2是文件系统是可写的,开发者只需将编好的用户程序 通过FTP下载到uClinux中,再改一改启动脚本即可 省去了配置uClinux环境的重复劳动 -err
