4*4键盘控制程序 //分三个部分，数字键部分，小数点，方向键部分，功能键(ok)部分。可以在不同的页面调// //用相应的功能实现菜单操作。 方向键部分///////////////////////////////////// //无返回值，无输入参数，用到全局变量page_number,xposition,yposition,scroll_value// -4* 4 keyboard control program// is divided into three parts, part number keys, decimal point, the arrow keys of the function keys (ok) part. Can be adjusted in different page//// using the corresponding menu realize the functions of the operation. Part of the arrow keys /////////////////////////////////////// no return value, no input parameters, use global variables page_number, xposition, yposition, scroll_value//

基于STM32的4轴步进电机加减速控制全套工程源码，共有两套；一套是STM32F103的，另外一套是STM32F405的；可以同时控制4轴步进电机进行加减速；速率可以达到100K以上；源码算法是基于《AVR446: Linear speed control of stepper motor》

本人自己制作的JTAG下载线，只用了一片244,可以支持ARM9、Cortex™ -M3、CPLD、FPGA、89S52等。目前这些已经测试通过。性能稳定。但是注意74LS244和74HC244在性能上可能会有些区别-I own the JTAG download cable, only a 244, can support the ARM9, Cortex

ARM的调试下载工具H-JTAG V0.9.0，H-JTAG是一款简单易用的的调试代理软件，包括两个工具软件：H-JTAG SERVER和 H-FLASHER。其中，H-JTAG SERVER实现调试代理的功能，而 H-FLASHER则实现了 FLASH烧写的功能。-ARM debug tools download H-JTAG V0.9.0, H-JTAG is a easy-to-use software debug agent, which includes two tools: H-JTAG SERVER and H-FLASHER. One, H-JTAG SERVER debug agent functions, and H-FLASHER is a FLASH programmer functions.

FM25L256B是采用先进的铁电技术制造的256Kb非易失性存储器。铁电随机存储器（FRAM）具有非易失性，并且可以象RAM一样快速读写。数据在掉电后可以保存10年，同时消除由EEPROM和其他非易失性存储器导致的复杂性，开销和系统级别可靠性问题。 -FM25L256B is the use of advanced technology manufacturing ferroelectric 256Kb nonvolatile memory. Ferroelectric random access memory (FRAM) with a non-volatile, and can read and write as quickly as RAM. Data can be saved in the power-down after 10 years, while eliminating by EEPROM and other nonvolatile memory led to the complexity, overhead and system level reliability problems.
