应用背景Abstract—Leros is a tiny microcontroller that is optimized for current low-cost FPGAs. Leros is designed with a balanced logic to on-chip memory relation. The design goal is a microcontroller that can be clocked in about half of the speed a pipelined on-chip memory and consuming less than 300 logic cells. The architecture, which follows from the design goals, is a pipelined 16-bit accumulator processor. An implementation of Leros needs at least one on-chip memory block and a few hundred logic cells. The application areas of Leros are twofold: First, it can be used as an intelligent peripheral device for auxiliary functions in an FPGA based system-on-chip design. Second, the very small size of Leros makes it an attractive softcore for many-core research with low-cost FPGAs.关键技术The smallest core is comparable to Leros and can be implemented

这是一个ntripclient的源码，主要是设置各种参数从ntripcaster上获取GNSS数据，然后将数据通过串口输出或写在文件里，源码比较实用，适合在linux操作系统下开发

motor speed by pwm this depond on that the pwm has t on and t off and t ther is a duty cycle that = ton / t this vry the average voltage across the motor-motor speed by pwm this depond on that the pwm has t on and t off and t ther is a duty cycle that = ton/t this vry the average voltage across the motor

1，mpu6050经过测试 2，代码详细，注释清楚 3，用串口和虚拟示波器测试 4，凯尔曼滤波完成既定任务

用c++编写嵌入式多任务操作系统- Compiles with c inserts the type multi- duties operating system

针对周立功2104板子的一个秒表程序,可以通过按键分别查看秒表的时间,分,秒.--A time counter program for Zhou Li Gong s 2104 board. You could check time, minute, and second by pressing keyboard keys.

希望从事C/C++嵌入式开发的朋友，可以看看，一些不错的题-Wishing to engage C/C++ Embedded Development friend, you can see, some good questions

周立功D12开发板中带的WINDOWS XP驱动程序，在编译后会出现USB设备不能正常工作. 以下是修改的代码,修改后可以正常工作. 在d12.c和Ioctl.c中, 将+256去掉,这个会引去枚举设备时,设备描述符的长度不对,修改后: siz = sizeof(USB_CONFIGURATION_DESCRIPTOR) 在d12.c中的D12_SelectInterface函数中, 设备查询完接口后有一段代码,也会引起驱动返回不对,需要屏蔽下面的代码 // Retrieve the selected Configuration and Interface 修改上面两处后,USB可以正常使用了. -weeks D12 development board, who were brought to the Windows XP drivers, the compiler will happen after the USB device not working properly. Following is the revised code, revised after normal work. In d12.c and Ioctl.c, 256 will be removed, this will generate to Enumerate equipment located descriptors up the length wrong, the revised : not = sizeof (USB_CONFIGURATION_DESCRIPTOR) in the D12_SelectInterface d12.c function, equipment End interface for a period after the code can also lead to wrong drivers need to shield the following code// Retrieve the selected Configuration Interface and the above two changes, USB can use the normal.
